Potassium Bichromate
A standard material in Glazecalc's library: its oxide analysis, unity contribution and hazards.

- Colorants
- Status
- Historical
- Formula
- K₂Cr₂O₇
- Also called
- Potassium dichromate
- Similar materials
- Chromium Oxide

- Theoretical formula
Toxic. Chromium is counted as Cr₂O₃; the LOI is the oxygen released as it decomposes.
Oxide analysis and unity formula
Glazecalc has the analysis of Potassium Bichromate as moles of each fired oxide per formula. The unity contribution is the moles of each oxide in the amount of Potassium Bichromate that holds 1.0 mole of flux, which is how Glazecalc adds it into a recipe's unity formula.
| Oxide | Moles | Unity contribution |
|---|---|---|
| K₂O | 1 | 1.000 |
| Cr₂O₃ | 1 | 1.000 |
- Equivalent weight
- 294.2
- Fired weight
- 246.18
- Loss on ignition
- 16.32%
The equivalent weight is the grams of Potassium Bichromate that hold 1.0 mole of flux. The fired weight is what is left of that after firing.
Hazards and safety
Hazards: Danger (Fisher UK SDS): H272 oxidiser; H301 toxic if swallowed; H312 harmful in contact with skin; H330 fatal if inhaled; H314 causes severe burns; H317/H334 skin and respiratory sensitiser; H340 may cause genetic defects; H350 may cause cancer; H360FD may damage fertility or the unborn child; H372 causes organ damage; H410 very toxic to aquatic life.
