Tips on How to Shop for an Electric Pottery Kiln

Many potters rely on electric pottery kilns for creating different effects. But the problem is that these kilns are expensive and hence it is important to consider some important factors before buying your first electric kiln. Electric pottery kilns are one of the most preferred firing methods mainly because of its ease of use. These kilns are generally preferred by contemporary ceramists over any other type of kilns. We are going to discuss some important features of electric pottery kilns which should be considered before buying a kiln for your workshop.

What are the Important Features of Electric Pottery Kilns?

Electric kilns are simple machines created from soft and highly insulated firebrick. Here are some of the important characteristics to be considered before buying an electric kiln.:
Power Supply of Kiln: If you are planning to run your kiln in residential area then don’t forget to ask about the voltage, phase, and amperage requirements of the machine. Generally a kiln designed for 208V is not compatible with regular residential supply (220V or 240V). You can find out these specifications on the outer casing or on the switch panel of the electric kiln.
Depth of Insulation of Electric Kiln: The kiln’s insulation depth is a crucial factor and depends on how you will be using your kiln. Generally most of the older kilns were built with 2” firebrick but these kilns are insufficient because of the heat leakage and low efficiency. It is recommended to go with a kiln of 3” to 3.5” firebrick.
Condition of Kiln’s Metal Skin: The main purpose of the kiln’s metal skin is to provide protection and keep all the firebricks in place. So make sure to check the metal skin beforehand and if you’re buying used, try to avoid dented kilns.
Inspect the Firebrick: You should look out for any possible damage to the firebrick within the kiln. Generally kilns get damaged around the rim of the door of the kiln and around the grooves, and the firebricks can be affected by dented metal sheets. The heat holding capacity of the kiln will decrease with any damage to the firebrick and the efficiency of the brick will be reduced.
Check Kiln Switches, Kiln Sitters, and Kiln Controllers: It is important to consider the types of controls used in the electric kiln. Some of the common parts found in modern electric kilns include kiln controllers, kiln sitters, and automatic electronic regulators which manage the power supply in different parts of the kiln. Make sure all of these are in working condition.
In the end, the choice of kiln depends on your personal or commercial needs. It is important that you should consider the purpose in which the kiln will be used which includes personal or commercial usage. Prepare a list of your requirements and then shop for a suitable electric kiln for your pottery creations!
