To begin controlled cooling, allow the kiln to cool as fast as it can for the first 300Â° so the controlled portion of the firing is taking place about 300Â° lower than the cut-off temperature.
One cost contemporary studio owners and artists need to know is the. costs of firing their kiln. This article will give you the information needed to calculate the costs of firing a. kiln. The information provided is for kilns that are about 10 cubic feet or about 28â diameter and 27â to. 29â deep. The tests were conducted using digital kilns with about 100 pounds of ware. To calculate the costs per firing we need to understand the formula behind the calculation. The formula is: (cost per kilowatt hour charged by electric company) x (kilowatt hour rating on kiln) x (the number of hours the kiln takes to complete a firing) x (the duty cycle of the kiln) The electric company charges for power in kilowatt hours. Electric costs range from $.07 to $.18 per kilowatt hour depending upon your location. The cost can be found on the bill from the power company.
