If you make your own glazes from percentage-based glazes recipes, this is a great tool for
you.
GlazeCal is a sliding ruler that calculates the gram weight of raw materials, based on the percentage
called for in a glaze recipe.
To Use: Simply move the slide to the correct batch weight and all of your glaze calculations are complete. Easily flip through to find the correct weight, of each ingredient (in the glaze recipe), under it's corresponding
percentage.
It works for batch sizes ranging from 500 grams to 10,000 grams, at intervals of 500 grams.
It measures percentages to the tenth decimal place.
GlazeCal is made of two 8.5" x 11" calculators. They are each made of sturdy, 2-sided calculator board and covered by a gloss varnish coating.
Each calculator is held together with metal eyelets and glue.
