- Theoretical formula
Water soluble. Caustic.
Oxide analysis and unity formula
Glazecalc has the analysis of Soda Ash as moles of each fired oxide per formula. The unity contribution is the moles of each oxide in the amount of Soda Ash that holds 1.0 mole of flux, which is how Glazecalc adds it into a recipe's unity formula.
| Oxide | Moles | Unity contribution |
|---|---|---|
| Na₂O | 1 | 1.000 |
- Equivalent weight
- 105.98
- Fired weight
- 61.98
- Loss on ignition
- 41.52%
The equivalent weight is the grams of Soda Ash that hold 1.0 mole of flux. The fired weight is what is left of that after firing.
Hazards and safety
Hazards: Warning (CTM SDS 69): H319 causes serious eye irritation.
