Soft Clay Bole for Watergilding Techniques. Sinopia has made the illusive art of laying and burnishing gold on a soft ground an accessible process, for both novices and masters.


The Sinopia Clay Boles are manufactured in house and have undergone years of development and field testing. We are proud to produce such standard colors as red, yellow, white, black, green and blue. Additionally, the Sinopia Test Kitchen is continually developing colors based on historical hues, which are based on actual samples we have secured or shades observed on ancient frames all over the world.


Sinopia hosts this page, in order to make the craft of watergilding more accessible to anyone and to serve as a reference for customers, who want to purchase our bole. Sinopia Clay Bole is sold direct on our web page,, or through our worldwide network of vendors.
