Make Art, Not Math!
A quick, easy way to reduce glaze calculation errors. GlazeCal is a slide rule that calculates the gram weight of raw materials based on the percentages listed in the glaze recipe. GlazeCal works with batches of different sizes up to 10,000 grams. Move the slide to your choice of batch weight, and flip through to find the correct weight for each ingredient. It's completely portable and independent, with no electrical power requirements at all. Glazecal is durable, too, made with sheets of water-resistant gloss-varnished calculator board held together with metal rivets and glue.
