This is a silicone mold for casting a square cigar ashtray. The finished cast measures 7 inches by 7 inches and is 1.5 inches deep. The cast comes out completely shiny.
The mold is made from Smooth-On Mold Star silicone, which cures to a soft, strong, tear-resistant rubber with very low long-term shrinkage. It works with resin, concrete, wax, gypsum and other materials. It is heat resistant up to 450°F (232°C) and can be used to cast low-temperature melt metal alloys. Each mold is handmade and inspected.
Do not touch the shiny inside surface of the mold, because it scuffs permanently and the scuffs show in the final cast. To clean it, tap loose particles gently with scotch tape. Make sure resin is fully cured before demolding, since uncured resin may rip the mold. Use extreme caution with a torch or heat gun to pop bubbles in resin, as heat may rip the mold. A mist of alcohol over the resin can be used instead. Resin is very toxic, so follow all safety precautions.
