Liquid Latex Rubbers Using Latex Rubber to make stuff. The latex rubber that we sell comes in liquid form. There are other companies who make it in sheet form for use in clothing, displays and props. The formula of latex which we carry is made for casting. It is also called slip latex, mask latex, liquid latex or slush latex. If it was made to be slip casted then it is this kind of latex. If it was made for carpet backing or other use, then I don't know what it is.How slip casting works: First of all, you need a mold that has two features; 1. It must be an absorbtive type mold (made out of UltraCal 30, which we carry.) and 2. It must be made from a type of plaster that is dimensionally stable. (UltraCal 30, Mold Plaster or #1 Pottery plaster all fit the bill.) When you pour latex into this kind of mold, the latex will stick to the wall of mold and form a skin. What is happening is simple; the latex contains water, the mold "wicks" the moisture out of the latex and so the latex sticks to the side of the mold. It eventually forms a skin. Now you pour out the "inside" portion of the latex. You can use this on another project later. The mold will have a slimy layer of latex stuck to the inside of the mold. Let this dry completly. TIP: I use one of those computer cooling fans you buy at Radio Shack (R). I simply mount it on two stickes and let it blow into the open mold. This will dry the latex out so that you can remove it. Latex is dry if you push it with your fingernail and it doesn't retain the imprint. You keep the latex in the mold until the skin gets to the desired thickness. If you mold is "green" (new and wet) this might be several hours. If the mold is dry it might only be about 15 minutes. Two suggestions if you want to learn more about this. First, get the little beginner kit we sell called "Shrunken Head Kit." this is just basic mask making on a small scale so you don't spend a fortune on materials only to discover that you don't like it. Also, please get some good information on the subject. A DVD or book will help a lot. Don't try to do this with only written instructions becasue it really, really helps to see how others do it. NOTE: Everybody has their own style and you will pick up some great tips from watching or reading many different sources. We no longer sell latex mold compound (except for the Non-ammonia latex).
