Artware flux calcium borosilicate frit; Fusion's listed equivalent of Vibrantz 3134. Versus 3134-2 (Ferro 2008): Al2O3 -1.20, B2O3 +1.01, SiO2 -0.56, CaO +0.49, Na2O +0.26 points; it melts slightly more fluidly.
Oxide analysis and unity formula
Glazecalc has the analysis of Fusion Frit F-12 as weight percent of the raw material. The unity contribution is the moles of each oxide in the amount of Fusion Frit F-12 that holds 1.0 mole of flux, which is how Glazecalc adds it into a recipe's unity formula.
| Oxide | Weight % | Unity contribution |
|---|---|---|
| Na₂O | 10.4 | 0.320 |
| CaO | 20 | 0.680 |
| B₂O₃ | 23.8 | 0.652 |
| Al₂O₃ | 0.8 | 0.015 |
| SiO₂ | 45 | 1.428 |
- Equivalent weight
- 190.68
- Fired weight
- 190.68
- Loss on ignition
- 0%
The equivalent weight is the grams of Fusion Frit F-12 that hold 1.0 mole of flux. The fired weight is what is left of that after firing.
Hazards and safety
Hazards: Non-hazardous glass powder per supplier SDS; avoid breathing dust.
