Raw Sienna Encaustic A versatile paint for fine artists, R&F Encaustics are composed of beeswax, damar resin and pigments. In a molten state, it is applied to an absorbent ground and then fused, or re-melted, to acheive a range of effects, from glass-like smoothness to rich, impasto-like textures. Luminous, deep golden undertone, excellent for glazing. Top tone is a rich caramel. Beautiful interplay of tones comes through in laying on a stroke of paint.Raw Sienna Encaustic A versatile paint for fine artists, R&F Encaustics are composed of beeswax, damar resin and pigments.
