Links to Other Materials
Miscellaneous
- Family: Frit
- Region: None
- Mined At: Unspecified
- Raw Mineral: No
- Generic: No
Notes
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.
Data
- Co-efficient of Linear Expansion: 3.96
