Calculating Approximate Costs
____________________________________________________________________
This information has been provided by Potterycrafts and is a guideline only. All kilns and firings are unique so these figures are an estimation only.
A = Kilowatt rating of kiln (see data plate).
B = Firing times in hours x 0.6 (since the kiln is only on full power towards the end of its cycle).
C = Cost per kilowatt/unit (taken fromyour electricity bill)
Example Calculation:
A x B x C = 5.5kw x 8 x (12 x 0.6) = £3.17p for a typical 8 hour bisque firing on a 5.5kw kiln appliance.
