Cutting Edge Magic: Why Silicone mold is Beloved by F/X Studios to Chocolatiers

Posted by EnvironMolds , Labels: , , , , Wednesday, January 24, 2024 4:38 AM

From artisan chocolates to custom concrete furnishings, silicone has become an indispensable asset for makers and hobbyists alike. With its durability, flexibility, and unmatched ability to capture fine detail, silicone empowers creators to keep pushing boundaries.

Understanding the properties that set silicone apart reveals why it has found a home everywhere from professional kitchens to special effects workshops. Whether whipping up an amber resin cast or shiny ingot of soap, discover how this material can elevate your projects.

What Makes Silicone So Exceptional?


Heat Tolerance

Silicone possesses impressive thermal stability, retaining its properties in temperatures ranging from -100° to upwards of 500°F. You can safely use silicone molds for casting wax or tempering delicate chocolates. Some specialized products designed for metalsmithing can even withstand molten metals exceeding 1200°F.

Flexibility

A hallmark of silicone is its bendability and elasticity. Complex mold geometries and deep undercut areas that crack rigid molds can flex and deform to release casts freely. This flexibility prevents damage during extraction, enabling multiple re-uses.

Durability

While silicone rubbers exhibit great flexibility, they are not easily torn or made to lose shape. Quality silicone holds up to years of regular casting use if properly maintained. Whether subjected to moisture, UV light, or humidity, silicone retains dimensional stability better than most alternatives.

Intricate Detail Resolution

Molten silicone easily picks up even the most subtle textures and details with accuracy and precision. Things like delicate feathers, lace patterns, or typography imprint clearly for high-fidelity reproduction. This aids creators in capturing realism.

Key Applications Leveraging Silicone’s Properties


Chocolate Making

Safe for food contact, resistant to high heat, and flexible enough to remove fragile tempered chocolate castings without breakage. Silicone offers chocolate makers the ideal material for yielding flawlessly detailed bonbons, pralines, or candy bars through intricate molds.

Candle Making

Candle makers harness silicone molds to impart striking embossed geometries, textures, and custom patterns into wax. Exceptional thermal properties allow molten wax to cure fully before flexible demolding. The results are wax creations with crisp details.

Resin Casting

The clarity of crystal-clear epoxy and polyurethane resins lets subtle mold details shine through vibrantly. Silicone picks up and replicates even the most minute textures and patterns without loss of accuracy. Resin artisans use this capability to encapsulate items inside hand-poured tabletop pieces with stunning realism.

Soap Making

It stands up to alkaline soaps without issue, unlike some mold alternatives which can react. Flexible soap molds yield intricately shaped bars, embossed designs, and custom textures while minimizing surface curing issues that can inhibit release. The bendability also prevents fragile soap castings from cracking or tearing during unmolding.

Concrete Casting

Recreating stone-like qualities in concrete relies on molds with excellent detail resolution to impart realism. While concrete cures, silicone’s flexibility enables unfolding of complex mold geometry and undercuts. The result: textured and imprinted concrete products that mimic Mediterranean tiles, rough-hewn plank wood, or fossil patterns.



Pushing Creative Boundaries


Jewelry makers leverage silicone’s heat resistance for lost-wax casting of silver and gold pieces. Special effects studios take advantage of flawless detail replication to produce masks, makeup prosthetics, and animatronics resembling skin. Chocolatiers transform cacao into delectable works of art through whimsical silicone molds.

Indeed, pushing creative limits seems to be silicone’s specialty. The material aids makers throughout every step of the process with properties uniquely fit for purpose.

Choosing the Best Silicone Products


With so many inferior silicone products flooding the market, finding quality can prove difficult. For mold making and casting, platinum-cure silicones represent the gold standard. Compared to tin-cured versions, platinum stands up better to repeated use without inhibiting finishes. These specialized rubbers also pick up finer details than cheaper alternatives.

Silicone Rubber Elevates Mold Making and Casting to New Heights!

Posted by EnvironMolds , Labels: , , , Friday, July 14, 2023 5:09 AM

Silicone rubber brings a host of advantages to the arts like mold making, casting and life casting. The level of flexibility, durability and capturing of details has to literally be seen to be believed!

Step aside all other mold making and casting materials, silicone rubber is truly the uncrowned king of these arts. This high-standing rubber has single-handedly revolutionized the art of making molds and casts with its game-changing characteristics and benefits. Let us take a look at some of the key features that lie in store for mold makers, casting artists and life casting artists:
 
 

Captures fine details – No material can come close to replicating the level of detail and accuracy as captured by silicone molds and casts. The rubber will precisely reproduce even the finest of lines, texture and other delicate contours, thus ensuring that the original object is as closely replicated as possible. This serves as an especially valuable feature in prototyping applications.

Flexibility – Most molds and casts tend to be rigid – they cannot be bent, stretched or even flexed without compromising their shape or integrity. Silicone rubber is the material that proves to be inherently elastic and flexible. Therefore, even the most complex molds and intricate casts can be easily demolded sans any damage or losing the details.

Durability and Reusability – Silicone molds and casts are found to be of good quality and exceptionally long lasting. The molds can be used again and again to make multiple casts without showing any signs of wear and tear. Long-term use is possible as they can be stored for years without any deterioration. Other molds often need to be replaced frequently in high-volume casting applications.

Non-stick nature – The beauty of silicone rubber is that it does not stick to anything but itself. This eliminates the need for applying a release agent during mold making or casting. The additional layer can often interfere with the details, not to mention the need for extensive cleaning and processing after the mold making or casting is done.

Material compatibility – Silicone rubber is a versatile material that is compatible with a range of resins, rubbers, wax, plaster, concrete and other mold making and casting materials. It will not react with them or interfere with the curing process. The results stay reliable and consistent, thus allowing an element of experimentation in terms of material, technique, finish, etc.

Safe – This rubber is both safe and easy to work with. Even beginners can easily mix, pour and handle the material without facing any undue problems. It does not have toxic or even allergic properties. Nor does it require any safety equipment as it does not release any dangerous fumes under normal circumstances.

In sum, silicone rubbers bring precision and efficiency to mold making, casting and life casting. Intricate details and complex shapes can be reproduced with ease, especially when using the high-quality options available at EnvironMolds (https://www.artmolds.com/). Limitless possibilities are beckoning to unleash one’s creativity and bring visions to life!

Difference between Poured Block and Blanket Molds

Posted by EnvironMolds , Labels: , , , , , Monday, September 12, 2022 11:58 PM

The uses of silicone rubber across mold making and casting are too many to list. It can be used to make both block and blanket molds. Find out how to make these poured molds using silicone rubber.

Silicone rubber is an inherently versatile material which lends itself well to various applications in both mold making and casting. When it comes to mold making, both the poured block and poured blanket molds can be made using silicone rubber. Let us take a look at both these techniques:
 

Poured block mold – This is considered the simplest method for making a mold. All it requires is making a containment area or a mold box. For this, the model is first secured to a flat base and the edges are sealed with clay or glue. The walls of the box can be made using particle board, plywood, PVC pipes, etc. These walls will have to be secured together as well as to the bottom of the box before sealing the interior edges and corners to prevent leakage of any kind. Alternatively, the walls can be fashioned with clay itself.

Once the mold box is ready, making the mold is as easy as simply pouring the mixed silicone rubber into the box till it completely covers the model and then some more. This should be done from a corner while avoiding pouring directly over the model. Let it cure proper before demolding by dismantling the mold box and prying the mold loose. The mold will be ready for casting.

This technique does require a lot of rubber but is preferred for its simplicity.

 

Poured blanket molds – This is a more complicated process as it requires constructing a mold shell over the model which will take some practice. Here also the model is first secured to a base. Then it is covered with plastic wrap before applying clay to about half inch thickness. This should be uniform and fill all undercuts in the model. The clay is extended to form a flange and a pour hole is also needed.

A thickened mixture of polyurethane resin is applied over the clay and legs are added that will serve to hold and level the mold later on. Holes are drilled evenly throughout the plastic flange that will help in repositioning and screwing later.

Once cured, the mold shell is demolded and the clay is removed from inside. The model is again glued to the board and the plastic shell is repositioned over it by aligning the holes before securing it to the base with screws. Sealing the edges with clay will prevent leakage.

Mixed silicone rubber is poured inside through the hole at the top. This will cure to form a mold in place of the clay. The mold shell is removed and he edges of the silicone mold are loosened for demolding it from the model. When casting, the mold has to be placed in the shell mold again.

It is clear that this process may be complicated, but will require much less mold making material. The final casting will be easier to demold too as the poured blanket molds are thin and flexible.

How to Make Molds Using Silicone Rubber?

Posted by EnvironMolds , Labels: , , , , , Thursday, June 9, 2022 6:03 AM

Silicone rubber makes the most perfect mold reproductions that become the base for casts. Find out more about the different techniques of making silicone molds as well as how to use them in the casting process.

Silicone rubber is a versatile material that is commonly used in art studios to make molds and casts. It offers an interesting array of useful properties that lend themselves well to these arts. As a mold making material, it reproduces the precise shape of the model and can be used to make a wide variety of reproductions.

The common methods of making silicone molds is either pouring or lamination. In the former, the model is kept inside a mold box and the rubber is directly poured on to it. This process requires just a couple of steps and the mold is ready in the minimum time possible. It is preferred for making molds of furniture parts, ornaments and fine handicrafts.

The lamination method is also known as skin molding. It involves creating a skin of even thickness by laminating the rubber onto the model. The mold is reinforced with a shell mold. The process is not only quick, it also requires less quantity of material and results in a lightweight mold. This is the method of choice for reproducing artworks and other three-dimensional figures. It is also preferred for creating molds of large figures.

Both the methods will replicate even the minute surface details of the model in their entirety and become a perfect negative impression of the model.



Making the Casting


Once the silicone mold is ready and cured properly, anything from wax or plaster to resin can be cast in the mold to create a perfect reproduction of the model. Both the mold making and casting processes work beautifully as silicone rubber does not stick to anything (except itself). Demolding is a breeze and the flexible mold can be finished/corrected as needed before making casts.

The silicone molds are always durable and long-lasting. They can be used and reused any number of times provided they are cleaned and stored properly between uses. The casts will turn out perfect every single time. It is advisable to dust the mold with talcum powder before storing away from sunlight to ensure that the mold does not flop or become sticky.

What’s more, it is possible to even cast silicone rubber in these molds as long as a good release agent is being used. When it comes to finishing a silicone cast, it calls for special silicone paints as the regular ones will tend to chip and crack on the rubber surface.

Where to buy?


EnvironMolds (https://www.artmolds.com/) offers a varied collection of silicone rubber options for general mold making apart from specific purposes like food molds, body molds, 5 minute molds and even doll reborning. The materials are of excellent quality and yet priced vey reasonably. In addition to this, the special silicone paint is also available for finishing silicone casts.

Mold Making Methods for Silicone Rubber

Posted by EnvironMolds , Labels: , , , , , , Wednesday, March 9, 2022 9:55 PM

Silicone rubber is the ideal material for mold making. There are different methods of making silicone molds – from general to inversion and vacuum – and each delivers top quality molds every time.

Silicone rubber is considered the material of choice for making both molds and casts. The rubber is suitable for making molds of all kinds – from reproducing figurines and giftware to making automotive parts, toys and other prototypes - and gives quality results every time. Moreover, it is easily workable, flows well and is non-exothermic in nature. The rubber always cures uniformly, irrespective of the thickness. It will demold easily as well because silicone rubber does not stick to anything except itself.


SkinRite10

Mold making methods


Molds of silicone rubbers can be made using different techniques. The most common are the general molds which easily replicate the surface details of the model in a negative mold. The silicone rubber is mixed with the catalyst and is simply poured over the model (which is affixed inside a mold box). The mold is easy and quick to make while giving efficient results. It does not require any special skills either.

Otherwise, there is the lamination method, wherein the mold making rubber is painted on the model one coat after the other. This creates a skin of even thickness and the mold can be reinforced with a shell mold if needed. These molds will be lightweight and do not use much of the material either.

Some artists prefer the inverted mold method, wherein first a silicone rubber mold is created and resin or gypsum is poured into it to make a replica of the original model. This method is used to create subsequent molds as part of the inversion process. The subsequent molds can be used anytime for making castings of choice. The lost wax method is a popular method of inversion mold making.

Then there are high precision molds which are made created using a vacuum device. The mold is placed inside the vacuum chamber and the casting material – usually resin or other rubbers – is poured before being vacuumed so as to eliminate any possible defects and air bubbles.


BakeSil

Where to buy?


EnvironMolds offers a wide variety of silicone rubbers, both for mold making and casting purposes. First there is the standard silicone mold rubber that lends itself well for general mold making. Then there is the faster acting silicone mold for making quick impressions without using a mold box, called 5-Minute Mold Putty. In addition to this, there are food safe and skin safe silicone mold rubbers – BakeSil is FDA approved as food safe for making food molds and baking containers while LifeRite, can be used on the skin for life casting and duplicating body parts. And what tops the charts is SkinRite10 - a translucent silicone mold rubber which can be tinted and used for special effects and applications to duplicate skin surfaces, making it the ideal material for realistic masks apart from doll reborning.

Effect of Temperature on Mold Making and Casting

Posted by EnvironMolds , Labels: , , , , Wednesday, November 10, 2021 2:15 AM

Temperature can play havoc with the curing of molds and casts by delaying/accelerating the process or not allowing the material to cure at all. Knowledge of the properties will ensure better results.

It is not just about the technique or dexterity of the artist; the quality of the mold or cast is affected by many other characteristics as well. Temperature plays a starring role here – ranging from the temperature and humidity of the surroundings to even the warmth/coldness of the material and model/mold.

This is why it is always recommended that all rubber and resin compounds should be stored at room temperature (72°F/23°C). For instance, if a material is stored at elevated temperatures, like in a hot garage or in direct sunlight, both the shelf life and pot time will get reduced drastically. In contrast, if latex rubber freezes, it becomes unusable and has to be thrown away. Other frozen materials can still be used after they are brought back to room temperature.
 
Let us take a look at how the temperature factors can affect the making of molds and casts:

Cold – A cold environment will usually prolong both the working time and cure time of most materials like epoxy resins, urethane rubbers and platinum cure silicones. The evaporation process of latex rubber also gets delayed in colder temperatures. In case the environment is too cold, some of these materials may even fail to cure at all. However, tin-cured silicones are not as dramatically affected by colder temperatures.

Heat – The opposite is also true as higher temperatures are known to accelerate the cure time and most materials tend to cure much more quickly when it is hot. In fact, many artists deliberately apply heat to hasten the curing process. However, tin-cured silicone rubbers are again an exception as they are not as affected by heat and cannot be ‘heat cured’.

Humidity – Rubbers are best used in a low humidity environment. Higher humidity tends to accelerate the curing in tin-cured silicone rubbers while it has the opposite effect of slowing the evaporation and curing process in latex rubbers. Making molds or casts of urethane rubbers, plastics or foams in humid environments can cause bubbles or foaming in the material. However, platinum-cured silicones and epoxy materials are not affected by humidity.

In addition to this, if the model that is being used to make the mold happens to be too cold, the curing of the mold will take unnecessarily longer to cure and vice versa. Therefore, the model/mold should be brought to room temperature prior to use. When making a mold of a frozen model, it will start condensing once the mold material is applied which will in turn delay the curing. This is why it is better to use accelerated silicones as they will not be affected by the moisture.

Finally, good quality liquid latex rubber, silicone or epoxy materials can be easily sourced from EnvironMolds at https://www.artmolds.com/ at the most reasonable prices.

Silicone Rubber - Different Faces and Usage

Posted by EnvironMolds , Labels: , , , , Tuesday, April 13, 2021 6:38 AM

Silicone rubber is a versatile material that is used for different purposes in both the art and manufacturing world. It displays many useful properties and comes in a few different types too.

Silicone rubber is a popular compound that enjoys widespread patronage across industries and applications. It is commonly used for bonding, sealing, potting, encapsulation, coating, mold making and casting works.

The main benefit is that silicone rubber molds that can be used for manufacturing different types of technical and mechanical parts for industry and medical devices. Apart from molds, silicone rubber is also used as a release agent, adhesive or the base material for the cast. It also functions well in the potting of electronic components in high-tech industrial and scientific equipment.

Artists normally use the rubber to make molds for toys, candles, soaps, food and baking containers apart from special effects. There is a special variety of silicone rubber that is safe for the skin and is used to make body molds.

The same rubber can be used to make casts too and is the material of choice for mask making and doll reborning.


Getting to know Silicone Rubber


RTV silicone rubber is commonly used for molding and casting projects. It delivers various useful properties like ease of use, flexible, tough, durable and tear resistant. This versatile material can reproduce almost anything without damaging the surface of the model. What’s more, the excellent mechanical properties and low surface tension enable it to replicate the mold without losing any of intricacies of the original - the minutest of details will be captured in the mold even down to the skin pores and fingerprints. It can even be cast in abrasive materials.

Silicone rubber formulas are remarkably stable in a wide temperature range and prove to be non-flammable and non-combustible. There is a good level of thermal conductivity too.

The room temperature vulcanizing rubber comes as a 2-part formula – one is the liquid base and the other is the catalyst. They have to be mixed in the specified proportion which can vary from formula to formula. The catalyst will react with the base to deliver the intended properties. It can even be customized to produce the required degree of viscosity and adherence along with varying mechanical, chemical or temperature resistance characteristics.

The rubber comes in two different types – addition cure and condensation cure. The primary difference is in the catalyst - Addition cure silicones use a platinum-based catalyst (usually 10%) while condensation cure silicones need a tin-based catalyst (usually 5%). They have different characteristics and usage and most importantly, are not compatible with each other.

EnvironMolds offers a broad range of materials, supplies, tools and equipment that include both silicone mold and casting rubbers. There are different formulae options to suit varying needs and preferences, like MoldRite 25 Silicone - Classic Mold Making Silicone, BluMold RTV Silicone, 5-Minute Mold Putty for Faster Mold Making, Food Safe Silicone -- BakeSil FDA Approved, LifeRite Skin Safe Silicone for Life Casting and SkinRite 10 Translucent Special F/X Silicone.

Difference Between Plastic and Silicone Molds

Posted by EnvironMolds , Labels: , , , , Monday, January 18, 2021 9:05 AM

Which is better – plastic or silicone molds for making castings of resins and other materials? Both options come with their own pros and cons. Generally, silicone ones are preferred by professionals.

The technique of making a cast begins with a mold. The casting artist will either make a mold or use a ready mold for making the cast. The casting material is usually poured into the mold and allowed to set before being demolded. Once it has cured properly, it is finished and is ready for use. How to make a mold for the casting is another story for another day.



However, here we shall take a look at the type of molds to be used for making a cast. Let’s consider plastic and silicone molds for instance.

Plastic molds usually have a lot going for them. They are easily available in the market in a variety of shapes and sizes. They are flexible, reusable and quite inexpensive at that. Being quite easy to work with, these molds are considered apt for novices stepping into the world of casting. Even if the molds get damaged, they can be easily replaced or even discarded if someone loses interest in the hobby.

On the other hand, silicone rubber molds are more sophisticated and top quality molds that are preferred by professional casting artists around the world. They may seem like a substantial investment initially, but this does pay off in more ways than one.

The biggest thing working in favor of silicone molds is that they can be customized as desired. The mold maker can make single or two part molds of any item that is to be replicated as a cast. However, making a plastic mold calls for specialized techniques and equipment for working on vacuum forming sheet plastic around a template. Therefore, making casts from plastic molds can be limiting based on the ready molds available.

Then again, casts made in plastic molds do not turn out glossy enough. The molds tend to get scratches easily, which also affects the quality of the castings. The surface that is touching the mold will have to be recoated with either the casting material or a sealer to make it shiny. On the other hand, castings from silicone molds have a smooth and shiny finish that is pleasing to the eye.

These molds also lend themselves well for making complex castings. Demolding is especially easy even for complicated shapes as silicone does not stick to anything except itself. It should be kept in mind that silicone molds are extremely durable, but only as long as they are cleaned and stored properly.

EnvironMolds offers a range of materials, supplies and equipment including a great selection of high quality silicone rubber formulas that are suitable for both mold making and casting. Indeed, most silicone mold rubbers can double up as casting rubbers too. However, artists should bear in mind that silicone rubber should never be cast in silicone molds as they will tend to stick to each other.

Painting on Silicone Casts

Posted by EnvironMolds , Labels: , , , , Tuesday, December 1, 2020 3:35 AM

 Finishing silicone casts with paint is a challenging task as regular paints tend to crack or chip off very soon. EnvironMolds brings a special dye and paint system that will easily incorporate into the silicone.


Silicone rubber is a versatile material that is used to make both molds and casts to suit different applications. It is easy to use – just mix in the required quantity of base and catalyst in the prescribed ratios and you are ready to go. Moreover, as silicone does not stick to anything but itself, the mold making and casting process is relatively straightforward and effortless. The rubber can be specially formulated to be food or even skin safe, thus lending itself well for making food and body molds.

However, the problem arises when the artist tries to paint on a silicone cast. Indeed, you may feel like finishing the cast with a beautiful color of choice, however, regular paints will start cracking, chipping and wear away with time.

Alas, the smooth finish and waterproof qualities of the silicone weighs against it in this regard. Even if you use oil-based paints for their better adherence, the inherently flexible nature of the rubber will cause the paint to wear off easily.

At times, people try making the silicone surface rough by soaking it in denatured alcohol or rubbing it with sandpaper. While this can work for regular silicone caulking, the coarse facade will end up marring the silicone cast and render it unpleasant to the eye.

It is only special silicone paint and dye that can adhere to the silicone rubber and yield the desired finish. EnvironMolds (www.artmolds.com) offers the special Cirius silicone formulation for painting and dyeing silicone creations. The silicone base of the dye comes to the rescue here as silicone will definitely stick to itself! Try bending and twisting the silicone rubber cast as much as you wish – but the color will not crack, peel or even rub off as it has become chemically incorporated into the silicone!



How to use?

You can mix a few drops of the silicone dye with the base before adding the catalyst to give an intrinsic uniform hue during the casting process itself. Swirling one or two drops of dye in the mix can also create a lovely marbled effect in the silicone cast.

On the other hand, there is also the option of diluting the dye with a silicone medium for coloring after the cast is ready. It can then be painted, sprayed or air brushed on the silicone surface to get the desired finish. However, it is important that the cast should be cleaned and prepped properly prior to painting. The brushes should also be cleaned quickly after use.

This silicone paint is considered compatible with both tin and platinum cure silicone variants. However, the dye can interfere with the setting of platinum silicones.

Twelve different hues are available, including the famous ‘Quinn Blush' used by renowned doll rebirthing artist Terry Quinn to add skin blush to her silicone dolls.

How To Use Silicone Rubber

Posted by EnvironMolds , Labels: , , , , Tuesday, March 27, 2018 9:40 PM

Silicone rubber is a material of choice for making molds of figurines, giftware and robotic figures to even prototype tooling, prosthetic pieces and special effects. A wide variety of silicone rubbers are available in the market ranging from the regular silicone formulations to skin safe, food safe and skin-like translucent options.



Not only does silicone perfectly capture the surface details of a model, but the rubber is very simple to use too. Following is a look at what goes into making a simple silicone mold:

•    Silicone rubber is a two-component material with the base and catalyst usually mixed in the ratio of 10:1 by weight. You need to stir and shake them properly before weighing the appropriate amounts in separate containers. Place the base material in the mixing container and roll it around to coat the sides as well.

silicone RTV rubbers

•    Pour the catalyst into the container and mix them thoroughly making sure that any material is not left unblended on the sides or bottom. You should not use a mixer machine or even mix too vigorously as this will introduce air bubbles into the silicone rubber.

•    Despite the most careful mixing, some air is bound to get entrapped in the mix and will form unsightly bubbles on the mold. Degassing in a vacuum chamber will release the air and make the rubber bubble-free.

•    Once vacuumed, slowly pour the mixture in a thin stream from a corner of the mold box till a thick and even layer forms all over the model.



Quality Silicone Mold Rubbers


•    Keep in mind that though the work life of silicone varies from one brand to another, it is usually under an hour. Even the pot life is limited to a couple of hours at best.

•    As silicone rubber does not stick to anything but itself, it will get demolded easily. Yet, some mold makers prefer to coat a thin layer of release agent to allow the mold to slide off without any effort. Sealing the model and mold box is essential as the rubber may get absorbed into them.

•    The rubber mold requires 16 to 24 hours to air cure. Demold only when the mold feels rigid and is no longer tacky. Allow it to remain at least another day before proceeding to casting. Full cure may take almost a week.

•    The cured silicone rubber mold is usually blue in color. It will reproduce the exact detail, have a smooth finish and is ready for casting. You can cast polyurethane resin, epoxy resin, polyester resin, polyurethane rubber and many other materials in the silicone mold simply by pouring the material into the mold. Demolding the cast is also easy as silicone rubber will not stick to anything.

In sum, silicone rubbers are a great option for making molds of various objects.
