Product Description

GlazeCal is a cheat sheet for making glazes. It is a conversion chart slide rule that takes the math out of converting glaze recipe percentages into correct gram weight. Use it in place of doing the calculations or as a reference tool to double check your math. GlazeCal performs 16,000 mathematical calculations in just seconds. Always make sure that you follow the manufacturer recommendations for any supplies or materials used when making glazes or ceramics! Many are toxic!

A. How to Make a Glaze: First, there are a few items you will need in order to make a glaze. You can always make your own appropriate substitutions or omissions.

1. A sieve

2. Some type of mixer, depending on the batch size you'll be making

3. A scale to weigh the glaze (preferably a triple beam scale)

4. Glaze chemicals or raw materials that are called for in the glaze recipe

5. A glaze recipe

6. An approved mask

7. Two containers that are large enough to hold the batch size of the glaze you'll be making.

B. Obtain a Glaze Recipe: You can obtain a glaze recipe from a number of sources (a friend, glaze recipe book, web site, etc.)

Just make sure the glaze recipe is formulated for your type of firing and firing temp, along with your clay body.
