Glass Blowing Kilns
Select Your Kiln Type
Determine Capacity Needed
First, you need to find
out if the chamber of the kiln will be large enough to fire the pieces
you produce. The chart below lists the chamber sizes for each model.
The 3 things to consider when choosing the necessary chamber size are:
What are the dimensions of the largest piece you will want to fire?
What is the maximum volume of material that you will need to produce in a specific time frame?
How do feel your needs will grow in the next 5 years?
Use the following image as a reference for dimensions:

Determine Your Available Power Supply
The next step is to find a kiln that will operate on the electrical service
of your building. Ordering a kiln that does not match your electrical service
can be very frustrating and expensive to correct.
Most people will need to have an electrician install the wire from the circuit breaker panel to the wall receptacle as well as the receptacle. It is also wise to have the electrician verify voltage, amperage and phase when he visits on-site to estimate the job.

I want my kiln wired for the following voltage :240 Volts 208 Volts 120/208-240 Volts 115 Volts
My maximum amperage available for a new dedicated breaker is:30 Amps 40 Amps 50 Amps 60 Amps 70 Amps 80 Amps 90 Amps 100 Amps
I have these power supply phases available:1 3 1 and 3
Determine the Firing Temperature Needed
Now we need to find a kiln that will fire to a temperature that meets, and preferably exceeds, the temperature requirements of the materials you will be working with.
Kilns are designed to fire to a variety of temperature ranges. Materials such as porcelain and stoneware require the kiln to reach temperatures up to Cone 10 (2350 F) and materials such as glass only require the kiln to reach less then 1600 F. Whenever possible you should choose a kiln that exceeds your firing temperature needs. The use of 3" brick, the voltage and the phase of a kiln model can sometimes affect its maximum rating. If you are firing regularly to Cone 6 (2250 F) or above, we highly suggest you buy a kiln that is rated to Cone 10 (2350 F). Production Kilns, referred to as "PK" kilns, are specifically designed for the high fire production studio.
