This is a very low expansion frit (since it contains no Na2O or K2O). Use this as a base to make low expansion glazes. However a source of CaO and possibly other fluxes may be needed to melt properly. This is often added to low and medium fire glazes to solve crazing problems.

This analysis was confirmed with Fusion Sept 2013.
