Bole - Traditionally, bole is a term that
identifies a pigmented clay. This clay acts as
the base, or cushion, for the subsequent layer
of gold leaf. Classically terre-cotta in color,
the clay can be built up quickly, then polished
to a very smooth surface.
Contemporary gilding does not use clay, but
simulates the effect by adding a colored paint
that replicates the clay effect.
Size
- General term used to identify the
adhesive that attaches the leaf to a
surface.
There are different types of size, depending
on the form of gilding.
Traditional Water gilding
uses a
gelatin size.
Oil gilding (most common ) uses a
oil-based size.
Acrylic gilding
uses a water based
size.
Holiday - A
gilders term that refers to an area were the
leaf did not initially adhere.
Tack - Refers
to the state of the adhesive size. Proper tack
for gilding is the point when the size is not
longer wet, but not fully dry, hence it is
'tacky' or just slightly sticky.
Skewings
- The bits of leaf that are left over after a
surface has been completely gilded. Skewings can
be saved for other projects, making excellent
fillers for patching holidays.
