Well, first we will need to know how much glass you will use per week. An easy way is to 1) Weigh one of your typical pieces of glass 2) Multiply that weight by the number of pieces you plan to make per day. 3) Multiply that number by 5 days. 4) You can add a 25% margin for the glass at the bottom of the pot plus moil crack offs and punties. The idea is that you want to charge once a week. If you have to charge more frequently, you may spend more on gas than necessary, and less frequently tends to give lower glass quality.
