Get ready to cast

So you've got your molds ready now it's time to cast some sculpture. This lens is all about how to cast your sculptures using a variety of materials, polymer clay, plaster, resin, porcelain, and more.

Mold Making 

You need a mold to cast from, this lens tells you how.

Materials 

There are many materials out there to cast sculpture in. I can't begin to cover all of them and some like bronze casting really aren't suitable for doing in a home studio.


Casting Materials Covered in this Lens:

Polymer Clay - A man-made modeling compound composed mainly of PVC resin, plasticiser, and pigments as well as other fillers including mica.

Plaster - Quick-setting gypsum plaster consisting of a fine white powder, calcium sulfate hemihydrate, which hardens when moistened and allowed to dry.

Concrete - A hard, strong construction material consisting of sand, conglomerate gravel, pebbles, broken stone, or slag in a mortar or cement matrix.

Resin -

Porcelain and Other Clay Slip - Clay slip is made by adding water to clay to form a thick liquid.

Polymer Clay Casting 

Using Push Molds

Most casting is done using liquids that harden in the mold. Polymer clay is the exception. Soft polymer clay is pressed into a mold, usually of plaster or firm rubber, and then removed and baked to cure.

Note: There is some controversy in the polymer clay world about using push molds for sculpture. If you use one (especially if it is a purchased mold not one you created yourself) you should disclose the fact that you used a mold.

Polymer clay is generally a safe material to use however you should not use any dishes or utensils for food after being used for polymer clay and never exceed the recommended baking temperature.

Plaster and Concrete Casting 

Plaster and concrete have been around for millennia, the ancient Greeks and Romans used it for building. In the past plaster and concrete castings were made using molds of the same material that had to be broken to remove the casting, now flexible molds made of latex, silicone, or urethane rubbers are used for their durability.

Caution: Dry plaster and concrete can irritate the respiratory system so it should be used in a well ventilated area with safety glasses and dust mask/respirator. Curing plaster and concrete generates heat and can get hot enough to cause burns.

Resin Casting 

Plastic resin is a very new material. It typically comes in two parts mixed by either volume or weight (make sure you know which or the resin will not sure). Those mixed by volume are the easiest to work with since those mixed by weight require a very accurate scale to mix it properly.

Caution: Resins are toxic, use only in a well ventilated area with safety glasses and rubber gloves. Seek medical attention if resin comes in contact with eyes or mouth.

Build Your Own Roto-Caster Video 

For casting hollow resin figures.

DIY Roto-molding machine

This is an at-home roto-molding machine I whipped up in about 3 hours one night. To build one like it you will need: -About 20 dollars worth of Fisher Price Construx from ebay -A drill (DeWalt's fit nicely, but anything should work) -A few wood screws to hold down the Construx -A piece of scrap wood For my casting material I like using Alumilite and Polytek resins, they are both REALLY easy to work with and fairly cheap. Any RTV resin should work well as long as it has a short set time.

Slip Casting 

Slip casting is a casting method where liquid clay slip is poured into a plaster mold and allowed to partially dry (firm but still pliable) in the mold before removing. In hollow casting excess slip is poured off after a firmer layer has formed in the mold.
