Oxide analysis and unity formula

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

Oxides in Pearl Ash
Oxide Moles Unity contribution
K₂O11.000
Equivalent weight
138.2
Fired weight
94.2
Loss on ignition
31.84%

The equivalent weight is the grams of Pearl Ash 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 carbonate): H315 causes skin irritation; H319 causes serious eye irritation; H335 may cause respiratory 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
