Techniques

Mural painting techniques include encaustic painting, fresco, oil painting, and tempera painting; the term fresco is in fact often used interchangeably with the terms mural or mural painting. Ceramics and, more recently, liquid silicates, acrylics, and fired porcelain enamel are other media often employed in mural art. Some modern murals have also been composed with photographs. Mosaics, often used to adorn walls and ceilings, are considered a separate genre, however.
