# Pot Drop Calculator

 Enter any two of the values below, select your glass, and click "Go!" Size:: mm in. diam. circum. Thickness:: millimeters inches Weight:: grams ounces Glass:: soda-lime borosilicate Gaffer casting

## How to use this calculator

 Size This calculator assumes your pot drop will be a circle. You can specify the target size by diameter (distance across the middle of the circle) or by circumference (distance around the circle). Thickness Most glass will usually try to be about 5 mm thick when left to its own under full fuse temperatures. Thicker pieces can be achieved by damming the glass. Weight Probably the most useful scenario for this tool is determining the amount of glass needed for a desired size pot drop. When solving for weight, you can still set the unit of measure (grams or ounces) and your results will be displayed in that unit. Glass Soda-lime glass includes most popular art glasses including Bullseye, Spectrum, Uroboros and float. If you aren't sure what kind of glass you have it is probably soda-lime.

Please I have a question when using the pot melt calculation how does one know what  is the length of the pot made to be kept. I have a mold with a hole 3 inches.

I will be doing it for the first time . I am in New Delhi India and here glass fusing is very new  in fact I can say I am one of the first ones to do it and I am just doing my trials. I imported my skutt kiln., and even Bulls eye glass had to be imported.

I do need a lot of guidence.

thank you

Pam,

Hope I understand what you mean by "length of the pot to be kept".  It sounds like you're trying to plan for the final piece.  First you make the "pot melt" THEN you kiln form that into the piece to be kept.  This calculator is designed for the first part.  It's intent is to take the guess work out of knowing how much glass to use to get a certain size (if the glass is left unrestrained).  So, for example, if you are planning to use a mold or drop ring in the second step I'd suggest using its diameter to guide your use of the pot melt calculator so you get a size that works with that mold or drop ring.  The length or height of your final piece is a separate issue involving the thickness of the glass.
