Lead Bisilicate
Lead Bisilicate
Lead Bisilicate is a 'true' Lead Bisilicate in that it contains 65-66% Lead Oxide, 32% Silica and 2% Alumina which acts as a stabiliser. This formulation allows for two molecules of silica to bond with 1 molecule of lead forming a Lead Bisilicate. Lead bisilicate is the frit generally used in low solubility glazes and standard borax frit for leadless glazes. Low Sol.
from £13.34 inc VAT

Lead Sesquisilicate
Lead Sesquisilicate
Often chosen for artisitic glazes where food safety is not required, this low solubility frit has a ratio of 1 part lead to 1.5 parts silica.
from £25.44 inc VAT
