![]() ![]() It becomes quite warm as it hardens and must cool down before continuing. Once this process is completed, you have to wait for the plaster to finish hardening. On the top so that it will stand flat when it's turned over. The plaster is built up to about 1" thick over the object and then flattened (Note that we did not use the artichoke that I brought which was way too complicated even for a two-part mold.)Īs the plaster becomes thicker and thicker, it is smoothed onto the object For this we used clay to model an uncomplicated shape. We began with the simplest type of mold - just one part - and made on a simple object with no undercuts. Here Kim has just added the first layer of plaster over the clay object she is molding After that you begin slowly stirring it with one hand so you can feel the viscosity change. The way it's mixed is to fill a flexible plastic container about half full with cold water and then add plaster to it by the handful, crumbling each handful into the water to eliminate any lumps.When the dry plaster builds up enough to be visible on the top of the water, you stop adding more and let it sit without stirring or jostling for about five minutes until it sets up. If you can store it in a sealed plastic bucket, it will probably stay more moisture free. It's important to store it in a dry place as once moisture reaches it, it will harden and become unusable. ![]() It can be bought in small sacks or plastic containers in hardwares or home stores, but is much less expensive to buy by the bag. I started out thinking that I was really more interested in the plaster objects than in those made out of wax, but I have to admit that the wax objects are pretty alluring.īefore we began making molds, Kim explained about plaster, also referred to as plaster of Paris, but sold as "gypsum plaster" in large paper bags. I do not use either plaster or cast wax in the work I'm making currently, but it never hurts to learn something that may rattle around in your mind for a while and be useful some time in the future. I was really happy to see that Kim Bernard was doing a one-day workshop on making plaster molds for casting wax and signed up right away. The week of workshops held after the encaustic conference at the Truro Center for the Arts at Castle Hill (the "post-con workshops") are a great opportunity to pick up some new techniques or skills firsthand from specialists.
