Inlaid decoration is a type of decorative art that involves inserting pieces of different materials into a base material to create a pattern or design. The three main types of inlaid decoration are buhl, MOSAIC, and intarsia. Buhl is a type of inlaid decoration that uses thin pieces of metal, ivory, or tortoiseshell to create intricate patterns. MOSAIC is a type of inlaid decoration that uses small pieces of glass, stone, or ceramic to create a colorful pattern. Intarsia is a type of inlaid decoration that uses wood pieces of different colors and grains to create a pattern.
