R&F Impasto Modeling Wax is a blend of microcrystalline (petroleum) waxes and beeswax. It is designed for sculptural purposes. R&F Impasto Modeling Wax can be cast, carved, and layered to create a textural surface in encaustics. Impasto Medium is available in 333 ml cakes. The melting point of the impasto modeling wax (175°F, 79°C) is a higher temperature than the melting point of encaustic wax (approximately 162°F, 72°C). The difference in temperature allows one to paint and fuse encaustics over a shape without immediately blunting sculptural details or impasto effects.
