Molds are for cold processed, hot processed, melt & pour soap, candies, chocolate, wax applications and ceramic crafts when mold guidelines/pouring temperatures are followed. (To avoid cross-contamination, do not use for food/chocolates after using for soap making). Molds can tolerate temperatures up to 145 degrees F. Above this temperature, warping may occur. Wash molds in warm soapy water. Avoid placing molds in dishwasher as this can cause molds to become brittle and susceptible to cracking. Hot dish water may warp the molds. Soap is easiest to release 12-24 hours after cooling.
