Anotations

Scope note:

A matte, opaque water-soluble paint typically having gum arabic, gum senegal, or dextrin as a binder. Gouache differs from watercolor paints primarily through the addition of white fillers, such as chalk or baryte, which give it a higher opacity and matte surface quality. Gouache was used for miniature paintings in the 16th-18th centuries, for decorative paintings on interior walls, and for printing wall paper patterns. The term originally had a different meaning, referring to oil applied on top of tempera painting.
