Glaze Calculator

If the glaze calculator doesn't appear here then your browser cannot work with Java applets.

The KPA Glaze Calculator is a program for converting the recipe of a glaze into a formula. The formula can be used to compare one glaze against another or to predict how the glaze might behave in a given firing.

Instructions

Click on the "drop down" arrow to the right of the material selector and click on the material you want to use. The usual basic materials are in the list, but it is not possible to include all the different frits available worldwide, so in that case pick the one you think is closest. Enter the quantity in the "Parts" box - this can be in any unit as long as the units you use for all the materials is the same. They do not need to add up to 100. Click the "Update Recipe" button. Repeat these steps until your recipe appears complete in the list area.

If you need to change the quantity of any ingredient you can click on it in the list area, and the name and quantity will be copied back to the entry area, where you can update it and then click "Update Recipe" again. To delete a material completely, select it in your recipe by clicking on it, and then click the "Delete Material" button.

When your recipe is complete, you can press the "Recipe to Formula" button at the bottom of the window, and you should see the recipe converted to the usual unity formula representation in the lower half of the window.

The program is provided with no guarantees, and no-one I can think of will accept any kind of liability for faults it may have. However if you do discover a fault - do get in touch I will see what can be done.
