Dense, lead-free, zircon-opacified white frit (about 12% ZrO2) for white and pastel earthenware glazes at 1040-1100°C (Walker; expansion 59 x10^-7). Walker Ceramics has sold Frit 9113 in its place since 2022 (listed for a time as 9117), but no analysis of 9113 is published.
Oxide analysis and unity formula
Glazecalc has the analysis of Ferro Frit 9146 (zircon white) as weight percent of the raw material. The unity contribution is the moles of each oxide in the amount of Ferro Frit 9146 (zircon white) that holds 1.0 mole of flux, which is how Glazecalc adds it into a recipe's unity formula.
| Oxide | Weight % | Unity contribution |
|---|---|---|
| SiO₂ | 56.44 | 4.045 |
| Al₂O₃ | 4.1 | 0.173 |
| B₂O₃ | 13.53 | 0.837 |
| CaO | 6 | 0.461 |
| MgO | 0.6 | 0.064 |
| Na₂O | 6 | 0.417 |
| ZnO | 1.1 | 0.058 |
| ZrO₂ | 12.23 | 0.427 |
- Equivalent weight
- 430.65
- Fired weight
- 430.65
- Loss on ignition
- 0%
The equivalent weight is the grams of Ferro Frit 9146 (zircon white) that hold 1.0 mole of flux. The fired weight is what is left of that after firing.
Hazards and safety
Hazards: No SDS seen. Frit is a ground glass with no free crystalline silica. It contains zirconium and zinc oxides in the glass. Avoid breathing the fine dust.
