The Unity Formula

'Recipe-to-Formula' calculations can be used to convert a recipe into it's unity formula.

This process involves lengthy and detailed (though relatively simple) arithmetic calculations using oxide analyses information about the raw materials obtained from the raw material's suppliers.

Prior to the advent of computers these calculations were done by hand making the process too time consuming for the average ceramist. Over the last ten years software such as MATRIX has been developed which will perform unity formula calculations in a matter of seconds

Using unity formulation as a tool in the understanding and manipulation of glazes is now a practical and rewarding option for all those working with clay or glaze.
