Notes on Meaning

• Not Actual Gold: It is critical to understand that "mosaic gold" is a pigment that gold, not a form of the precious metal itself. This distinguishes it from terms like "gold leaf" or "gold paint" which may contain real metal.
• Historical Technique: Its use often involved suspending the powder in a binding medium like lacquer or varnish to create a paint or glaze.
