Product Description Named after the mineral color that is chemically associated with azurite. Malachite and azurite were some of the only bright greens and blues from ancient times through the 18th Century. R&F’s malachite green shares a similar bond with their azure blue. Warm hues bring out the malachite’s bluishness. Encaustic paint is composed of pigment, beeswax and resin. It is applied molten to a surface and fused to create a lustrous enamel effect. It is among the most durable of all artists’ paints, since wax is impervious to moisture and over time retains all the freshness of a newly finished work.. Once the surface has cooled, the paint has reached a permanent finish, but the painting can also be revised and reworked at any time — whether seconds or years later. Encaustics need to be applied to a rigid substrate such as a panel or hard board.
