Miscellaneous
- Family: Frit
- Region: North America
- Mined At: Unspecified
- Raw Mineral: No

Notes
Frits like this are the most effective way to reduce crazing because they intoduce a form of MgO that will melt much lower than MgO sourcing raw materials.
We have an article that deals extensively with how to introduce this material into a glaze, see the articles section of this page.
Data
- Co-efficient of Linear Expansion: 4.00
- Melting Range (C): 1900F

Bringing Out the Big Guns in Craze Control: MgO (G1215U)
MgO is the secret weapon of craze control. If your application can tolerate it you can create a cone 6 base glaze of very low thermal expansion that is very resistant to crazing.
