Gilders Clay - Borma Wachs

Description:

It is a natural clay paste, used as a colloid in the preparation of the background in the gouache gilding technique. Depending on the iron oxides that compose it, the bolus comes in various colors: red, yellow or black. The bole is used in gilding as a base for the metal leaf, guaranteeing the gilder a stable and perfectly homogeneous application. The color of the bole substantially affects the color depth of the gold or silver leaf, restoring a chromatic balance to the metal and giving it more warmth.

How to use:

Melt in a bain-marie using a 300 ml gilding pan. of bolus in 900 ml. of collection, previously prepared from Rabbit Glue, until obtaining a mixture with a fluid and light, but not watery, consistency.
The bole should be passed hot on the surface of the plaster, with a firm and light brushstroke, without leaving streaks. We recommend using the ox hair Bolo application brush.
If the bolus is diluted in the right proportion even a single coat is enough (you must not see the white background of the plaster), otherwise after about 4 hours you can apply a second coat, trying not to increase the thickness of the layer too much, which would cause to an inevitable detachment of the gold and the bole during the burnishing phase.
Usually the complete drying of the bole layer occurs in a few hours, however it depends on the humidity of the environment and the season of the year in which you are working.
