Ebonise refers to the process of making something black like ebony. It is a term often used in woodworking, where ebonising involves treating the wood with a solution that darkens it to a rich black colour. Synonyms for ebonise include "blacken", "darken", "char", "soot", "smudge", "stain", and "tarnish". Other ways to achieve a black finish on wood include painting, staining, or using a wood dye. Ebonising can be used to create a dramatic effect in furniture, floors, and other woodwork. It is particularly popular in Art Deco and modernist design, where the use of black is often used to create a stark contrast with other materials, such as chrome and glass.
