Olympic Raku Kiln Firing Information:

Because of the kindness of one of our customers, we have some additional information to help you have success with these kilns.  Remember your results may vary base upon altitude, temperature and other conditions, but this should help get you started.

Also, check your Olympic documentation for updates.

For a 23" Olympic kiln, PROPANE configuration, keep the following in mind

Regulator:  
Get a low pressure regulator with an 11" water column.

Gas Supply Hose:  
The inside diameter must be at least 1/2" diameter.  Olympic recommends 3/4"

BASO ignition device:  
This will take up to 3/4" hose but a 1/2" is recommend.  120 v household power is required to operate the ignition device.

Propane tank:
25 pound propane tank has been shown to work, but consider getting a larger one, especially in cold climates.

Note about these kilns: 
These gas kilns look like electric kilns, complete with sections, but they are not as easy to fire.  Typically it takes much more testing and experimentation to get good results from a gas kiln.  Gas kilns are simply a more complex of a firing system.  For example, you may have to raise the bottom shelf, or put an extra shelf at the top of the kiln to get it to fire evenly.  You will also have to learn how to adjust the burners for an oxidation or reduction environment.  If you are willing to take on these types of issues, then these kilns can be a great alternative to a larger downdraft models, especially if you are on a tight budget.   But please be warned, gas kilns are not for beginners or for someone who just wants to press a button and have the kiln fire itself.
