R&F Encaustic Medium is recommended to form transparencies and extend paints. It is encaustic paint without pigment.
Created with the same mixture of purified and bleached beeswax and dammar resin as the R&F Encaustic Paints, this medium maintains film hardness and prevents blooming (clouds on the surface).
Our Impasto & Modeling Wax is a blend of microcrystalline (petroleum) waxes and beeswax. It is designed for sculptural purposes. The Impasto Modeling Wax can be cast, carved, and layered to create a textural surface.
Impasto Modeling Wax is not intended as a surface medium, but works well in combination with Encaustic Paints.
It is less expensive than encaustic medium, so thickly built-up forms and sculptural work can be done more cheaply.
The melting point of the impasto/modeling wax (175° F, 79° C) is a higher temperature than the melting point of encaustic (approximately 162°F, 72° C). The difference in temperature allows one to paint and fuse the encaustic over a shape without immediately blunting sculptural details or impasto effects.
