Gesso di Bologna

Starting at: £12.00

Gesso di Bologna is a bright white Calcium Sulphate, or gypsum, from Italy, which can be used as a substitute for whiting in the preparation of gesso. It is ground to a particularly fine powder, which makes it a suitable ground for gilding, as the small size of the particles allows for greater compression when burnishing. Learn More

Gypsum

It can also be added to acrylic primers to increase absorbency or add tooth to a surface. Learn More
