Oxide analysis and unity formula

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

Oxides in Sodium Nitrate
Oxide Moles Unity contribution
Na₂O11.000
Equivalent weight
169.99
Fired weight
61.98
Loss on ignition
63.54%

The equivalent weight is the grams of Sodium Nitrate 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): H272 may intensify fire (oxidiser); H319 causes serious eye irritation.

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