Probably your best bet

In Topic: Gas Vs. Electric- An Alternative View

Since FeO is a flux on silica, if the kiln is fired in reduction, and the reduction occurs when the body is still gas permeable to the CO molecule, AND there is some level of Fe2O3 present, then the added flux would likely produce a more fluid melt.  This impact might be what they are talking about.  Heavily iron fluxed glass in a body can promote brittleness... so generally too much is not a good thing even though it can decrease Apparent Pororsity figures.....so I can't believe that they are talking about that kind of level.


Never tested the two directly against each other for something like MOR.  (same body in electric and reduction gas)





Have heard anecdotal evidence of this....  Thanks JB for knowing that it's correct and also why ! .... you are the best!

The Sheffield one is darn close to perfect.

Not that far from albany, didn't take much modification of the natural clay there to make it almost identical empirically and physically


In Topic: 110/115 Kiln Does Not Have Standard 110/115 Plug

The 2 different 110 plugs indicate different amperage on the circuit and also should indicate the wiring in the wall as well.

The standard household outlet is for 15 amps max.

Very few kilns can run on such a small amount of amperage.

Household voltage kilns usually need a 20 amp breaker and circuit.


Don't just change the 15 amp outlet to the 20 amp outlet willy-nilly : the wiring from the panel to that outlet may only accommodate 15 amps max.

By pulling more amps than the wire can handle you are asking for trouble, like big trouble, like a fire.
