How do you keep clay castings from sticking to the mold? Clay can stick to the mold and distort the design when you pull the clay free. Remembering to use a release agent makes life much easier. Apply the mold release to your ball of clay before pushing it into the mold. If your clay still distorts when you pull it free of the mold, you can also try freezing the clay and mold for a few minutes before you separate them: this will make the clay firmer and help avoid distortion. Powders: Cornstarch is our personal favorite choice. It usually washes right off with cool water, though you may want to let the piece cool before rinsing it. TIP: Be careful not to overdo the corn starch and cover up the design.  A light dusting is all you need. Also using well conditioned clay insures longevity of your molds. Baby or Talcum powder is another alternative. However, some people think that this leaves a residue, even after washing. Residue, if there is any, can be sanded or buffed away. Brushes off the clay piece before or after baking. Baking soda may help control odors during curing. Mica powders, metal pulvers, embossing powders, and powdered chalk can be used, too, though they generally cost more than the other alternatives. Do double duty as a mold release and a decorative effect. Potato starch, rice flour, and arrowroot powder and other powdered food products may serve as release agents, as well. Liquids: Water - This is the cheapest alternative and a favorite, because it won't build up in crevices like other agents do. Water works especially well for detailed molds. Water is a good release for Premo and Sculpey, but isn't generally recommended for Fimo and Cernit, which absorb moisture. Glycerin - This can be useful for casting detailed items. Another benefit of using glycerin is that it doesn't affect surface treatments on the clay (like paint or Pearl-Ex). Armor-all - This product is silicone-based. Nothing will stick to it. While this makes it a good mold release, it can complicate things if you want to add surface treatments (including Future or Varathane) to the clay, afterwards. Petroleum-based release agents - Vaseline or mineral oil (baby oil) are sometimes used. Don't use these products with latex molds, however, because they will react with the mold and destroy it. To ensure that your mold will  be long-lasting, always use your molds on a flat surface only. Pressing clay or other substance into your mold in your hand instead of on a hard surface will make your mold weak and shorten the life of your molds. Our personal favorite mold release product when using polymer clay is corn starch. It’s safe and completely non-toxic. Dip a brush in the powder, then tap off the excess. Lightly dust mold cavity in a pouncing motion. Blow out excess powder to maintain detail. Enough to make oodles of projects! Find it here.
