Note: Most historic decorative finishes were over coated
with some kind of glaze. When cleaning or restoring historic
finishes care should be taken that these glazes are not destroyed.
Glazing is usually the application and manipulation
of a transparent or translucent coating over an opaque coating.
There are basically
methods of glazing that is subtractive and additive. The example
(top left) uses both methods. The wall was first brushed with a glaze then
while wet padded with rags. This removed glaze giving the wall
a soft mottled appearance. After this first step dried, other colors of
glaze were brushed on and softened with a clean dry brush while still wet.
