bronze powder
A metallic powder made from various bronze or
brass alloys and used principally in lacquer or
varnish vehicles, or with bronzing liquid, as the
so-called gold paint. The powder can be prepared
to duplicate every shade of gold from a pale or
lemon color to a deep coppery hue. Bronze powder
darkens or discolors after a relatively short
time, and this, plus the fact that the paint made
from it has a lackluster, grainy quality, makes it
unsuitable for use in bookbinding. (236 )
