In the late 1960's the standard Red Clay Bole in France changed color and the shade was lost forever. We were able to secure some samples of this historical Clay Bole for testing and color matching. This historical recreation of the Classic French Bole possesses the same deep rich orange brownish red shade that made this clay color so emblematic. Bole Clay for use in water gilding techniques. Use over traditional chalk gesso ground. Bole needs to be applied with a solution of rabbit skin glue. This Bole is manufactured by Sinopia. The formula was developed by working with master gilders to craft a rich creamy bole that burnishes to a beautiful highly reflective luster.
