Encaustic painting is an ancient art form that involves using heated beeswax mixed with colored pigments. The artist applies the molten wax to a surface, typically wood, and can manipulate it with tools or brushes. Once the wax cools, it hardens, creating a durable and textured finish. This technique allows for vibrant colors and intricate details, as the wax can be layered and carved into. Encaustic painting has been used since ancient times, notably by the Fayum mummy portraits in Egypt, and continues to be a popular medium among contemporary artists.
