Oxide analysis and unity formula

Glazecalc has the analysis of Niter as moles of each fired oxide per formula. The unity contribution is the moles of each oxide in the amount of Niter that holds 1.0 mole of flux, which is how Glazecalc adds it into a recipe's unity formula.

Oxides in Niter
Oxide Moles Unity contribution
K₂O11.000
Equivalent weight
202.22
Fired weight
94.2
Loss on ignition
53.42%

The equivalent weight is the grams of Niter that hold 1.0 mole of flux. The fired weight is what is left of that after firing.

Hazards and safety

Hazards: Warning (Fisher UK SDS, potassium nitrate): H272 may intensify fire (oxidiser); keep away from combustibles.

Glazecalc shows the hazard wording as its record gives it. It is not a full risk assessment, so read the safety data sheet from your supplier. Before you handle any glaze material, read Safe mixing and ventilation and Glaze safety at home.

Use it in a recipe

Add Niter to a recipe in the Glazecalc calculator to see what it does to a glaze's unity formula.
