Assuming you require a kiln for ceramics and pottery you would choose between a top loading kiln and a front loading kiln.
Glass kilns are more specific in design so this will only apply to ceramic kilns.
These will be less expensive to purchase than front loading kilns as they are made in greater quantities and of a cheaper construction, with less insulation. This makes them lighter, easier to move around and they give faster firing and cooling cycles.
These kilns run very hot on the outside so they should be protected and extraction provided in the room to remove the hot air.
The larger top loaders are awkward to load and are not good for people with back problems.
The electrical supply available will determine the size of kiln you can safely run.
A small top loading kiln operating from a standard 13 Amp plug socket will give you a chamber size of approximately 1½ cu.ft (40 litres).
The next size of kiln will operate from a 30Amp single phase supply (typically known as a cooker socket supply).
After that 45 Amp and 60Amp single phase supplies are normally catered for by kiln suppliers.
It is strongly recommended that you consult your local electrician first if you are thinking of purchasing a kiln, as this is your starting point.
- Ceramic cafes for speed of firing and cooling
- People who do not fire very often but want their own kiln
These kilns are manufactured with a stronger casing and will be heavier and more awkward to move around but easier to load. It would normally be necessary to have a site survey to ensure the kiln will go into the required position.
The kiln would normally be delivered on a tail-lift lorry and moved around with a pallet truck. The ideal delivery is straight off the lorry over even ground into the garage. If there are steps, gravel, narrow turnings, grass, slopes, etc., it makes the delivery more complicated.
If a school wants the kiln on the upper floor hopefully there will be a lift installed.

The electrical supply available will determine the size of kiln you can safely run.
The most common size of kiln is run from a 30 Amp single phase supply. The largest kiln normally on a single phase supply is 60 Amps but a normal household would not be able to run this. 45 Amps is typically the maximum.
The larger kilns would need a 3 phase supply.
It is strongly recommended that you consult your local electrician first if you are thinking of purchasing a new kiln, as this is your starting point.
Also think about cheap rate electricity if you are going to fire often.
- Schools and colleges
- Studios who want a longer lasting kiln
