Traditional clay bole and Insta-Clay for Traditional Water Gilding
Gilder’s burnish clay, or clay bole, is an essential part of the traditional water gilding system with gold and silver leaf. Applied in multiple thin coats over a primed or gesso surface, burnish clay allows water-gilded gold or silver to be polished to a mirror gloss finish.
Kolner Insta-Clay is a single-process base for water gilding, eliminating the need for glue, gesso, and bole. Developed by Kölner-GlanzGold-Grund to meet the demands of commercial producers of gilded objects, Insta-Clay is used to prepare moldings and other items for gilding. This innovative process replaces the complex and labor-intensive steps associated with traditional water gilding.
Whether you choose traditional clay bole or the innovative Kolner Insta-Clay, you will find that these materials provide excellent results for water gilding. Traditional clay bole, such as Selhamin burnish clay, offers the classic approach with its rich history and proven techniques. On the other hand, Kolner Insta-Clay streamlines the process, making it accessible and efficient for modern gilding applications.
