How is the unity formula for a glaze arrived at?

Unit 4 Topic 13
The Unity Formula

The unity formula for each raw material in the recipe provides the data from which the molecular parts values for each oxide in the glaze can be calculated.

Computer programmes such as MATRIX work from a raw material database built up from information provided by material suppliers.

There may be hundreds of materials in such a database allowing recipes from anywhere in the world to be analysed and converted into recipes containing locally available materials.
