A soda-potash-lime frit with no boron and almost no alumina. Its expansion is very high: 141 x 10^-7/K, with softening at 503 °C. It is used for raku, crackle and crystalline glazes and for strong alkaline blues and turquoises. Sold by Carl Jäger, BSZ, Keramik-Kraft, Hans Wolbring, Rantzauer Töpferbedarf and Ing. Lehrer (Austria).
Oxide analysis and unity formula
Glazecalc has the analysis of Mondré & Manz Frit M 1233 as weight percent of the raw material. The unity contribution is the moles of each oxide in the amount of Mondré & Manz Frit M 1233 that holds 1.0 mole of flux, which is how Glazecalc adds it into a recipe's unity formula.
| Oxide | Weight % | Unity contribution |
|---|---|---|
| SiO₂ | 66.4 | 2.397 |
| Al₂O₃ | 1.4 | 0.030 |
| CaO | 7.8 | 0.302 |
| K₂O | 13 | 0.299 |
| Na₂O | 11.4 | 0.399 |
- Equivalent weight
- 216.9
- Fired weight
- 216.9
- Loss on ignition
- 0%
The equivalent weight is the grams of Mondré & Manz Frit M 1233 that hold 1.0 mole of flux. The fired weight is what is left of that after firing.
Hazards and safety
Hazards: Leadless frit (glass, CAS 65997-18-4). The SDS supplied by Carl Jäger for this Mondré & Manz frit says it is not classified as hazardous under CLP. Avoid breathing the dust.
