Sometimes we would rather put our heads in the sand then face the reality of what it costs to run our kiln. Don't worry! Firing your kiln costs less than you’d imagine. Even though a kiln draws electricity, it does not draw it continually, so during a typical glass firing, a kiln's elements are drawing power only a fraction of the time. Most digital controllers allow you to enter your cost per kilowatt hour for electricity and they will report back the cost of the firing.
