Oxide analysis and unity formula
Glazecalc has the analysis of Mondré & Manz Raku Frit M 233 864 as weight percent of the raw material. The unity contribution is the moles of each oxide in the amount of Mondré & Manz Raku Frit M 233 864 that holds 1.0 mole of flux, which is how Glazecalc adds it into a recipe's unity formula.
| Oxide | Weight % | Unity contribution |
|---|---|---|
| SiO₂ | 53 | 3.505 |
| Al₂O₃ | 5.1 | 0.199 |
| B₂O₃ | 26.3 | 1.501 |
| Na₂O | 15.6 | 1.000 |
- Equivalent weight
- 397.3
- Fired weight
- 397.3
- Loss on ignition
- 0%
The equivalent weight is the grams of Mondré & Manz Raku Frit M 233 864 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) with a lot of boron. No SDS was found for this product. Some EU suppliers label boron-rich frits as toxic to reproduction (H360FD), so check the SDS that comes with the bag. Avoid breathing the dust.
