rubber skull mold

Most skull molds are made from high-quality silicone. Product listings repeatedly describe them as flexible, reusable silicone molds (often promoted for their durability and nonstick properties).

Listings specify a temperature range of approximately −40°F to 446°F (−40°C to 230°C).

Skull silicone molds are compatible with many casting materials, including epoxy resin, UV resin, polyester resin, casting resin, plaster, cement, mortar, clay, soap, wax (for candles), and soap bases.

The molds are described as durable, flexible, tear‑resistant, and reusable for multiple uses. To extend their life, store them away from direct sunlight, dust, and sources of heat or flame.

Clean molds by washing with warm soapy water to remove mica, glitter, or resin residue. For storage, keep molds in a dry place away from direct sunlight, dust, and fire to help preserve flexibility and longevity.
