Many students and ceramicists have trouble converting glaze recipe percentages into the correct gram
weight, based on the batch size they are making. They often make mistakes with this simple calculation and end up wasting expensive raw materials. Some students/ceramicists are terrified at the idea of doing math and therefore refrain from making their own glazes all together. Professors and instructors see students/customers pouring glazes out or having bad results at the end of a firing,
because of a glaze calculation error. GlazeCal is a conversion slide rule chart that converts the glaze recipe percentages into the correct gram weight. Therefore, when your student or customer is
distracted, tired, whatever the case may be, while mixing glazes, GlazeCal is there to help as either a reference tool so that they may double check their math or to act as the sole calculator, eliminating the need for the individuals to perform mathematical conversions.
