Encaustic painting is an ancient art form that uses pigmented wax as a medium. This technique involves heating the wax to a liquid state and applying it to a surface, such as wood or canvas. Encaustic painting is also known as hot wax painting and wax art. Another synonym for this medium is beeswax painting, as beeswax is often used in the creation of encaustic paintings. Other terms used to describe encaustic painting include wax painting, wax medium painting, and cold wax painting. Encaustic painting has gained renewed popularity in recent years, due in part to the wide variety of effects that can be achieved with this versatile medium.
