What technique involves pigment mixed with hot wax?

The technique that involves pigment mixed with hot wax is encaustic. Encaustic painting is one of the oldest forms of painting, dating back to ancient times, where artists would blend natural pigments with a hot wax medium. This mixture can be applied to a surface, and as it cools, it hardens, creating a durable and vibrant finish. The heat used in this technique allows for unique textures and layers, as artists can manipulate the wax and create depth and richness in their work.

Tempera refers to a method where pigments are mixed with a water-soluble binder, typically egg yolk, and is not related to wax. Fresco is a technique involving the application of water-based pigments onto freshly applied plaster, which does not involve wax either. Mosaic is a form of art that involves assembling small pieces of materials to create images or patterns, not a painting technique involving wax. Each of these techniques utilizes different materials and methods, highlighting the distinctiveness of encaustic painting.
