All About the Mold Making and Casting Materials

 There is a broad range of materials that can be used to make molds, casts and life casts. Check out some of the options available along with their varying properties and usage in the world of artwork.

EnvironMolds is home to a complete line of mold making and casting materials along with the requisite supplies, tools and equipment. Quality is always a top priority for this leading art supplier which actually makes a difference in the molds, casts and life casts.

Let us take a look at some of the commonly used products:

Latex rubber: Liquid latex rubber is an economical material that is easy to use as well. The molds turn out to be tough, durable and tear resistant. A slightly less viscous form of the rubber is suitable for casting purposes as well. In fact, latex casting rubber is regularly used for making masks and other special effects for films and stage.

Silicone rubber: This is a more expensive rubber but the efficiency and applications more than justify the price. Apart from regular silicone rubbers, there are special formulations for using on the human body, on food items and even for doll reborning. This rubber is again versatile and can be used for making silicone casts as well.


Resin: This family comprises of polyester, epoxy and polyurethane resins that come with their own set of properties and usage. Generally speaking, polyurethane resins are most preferred for making casts. This material lends itself well for cold casting that can replicate the look of different metals, stones, wood, etc.


Clay: Clay is a versatile material if ever there was one. It comes in different types and is suitable for a range of mold making applications apart from other minor uses like sealing edges, making mold boxes and so on. However, artists prefer plasticine to regular clay for molds.


Alginate: This dental impression material is not only safe for the skin but also captures details well. It is the material of choice for making body molds for life casting. Varying set types and times are available to suit different applications. But the molds are good for one-time use as they tend to shrink and have to be used quickly.

Moulage: This is a reusable mold making material that is heated to melt before use. The mold can be remelted and reused again and again. It is skin safe too.

Wax: This is a simple material that can be modeled, carved and cast as desired.

Plaster: This white powder can be mixed with water and used to cast objects. It is widely preferred for life castings. However, regular plaster of Paris is better avoided as it tends to get chalky and flaky over time. Plaster-embedded bandages are also available that can be used to make shell molds to provide support to flexible rubber molds.

Apart from latex rubber and other materials, the ArtMolds website also stocks release agents, fibers, fillers, cold casting powders and more.
