Brown Outs

Recommended Posts

I do firings in a Computer Controlled L&L Kiln. So far we haven't had an Electrical Brownout in the heatwave here. If this happens midfire (bisque or Glaze) will I have problems? I'll fire to^06 for Bisque and ^6 for glaze.

Andy,

 

 

It would not affect your pottery, you can just refire it. But, it's possible it could damage your kiln. I know we've lost food freezers in brown out. I would contact the manufacturer and check with them about what to do.

I dont know if brown outs hurt the actual kiln. I've found when the power goes off, it won't start up or keep trying to start by itself. Mine just flashes PF for power failure and all elements are off.

 

You should use witness cones so you can tell how far into the firing you got. Without them you won't realize it if you indeed got to temp before it happened.

 

Your bisque firing should be fine. Your glaze firing should be fine too if you refire it to the right temp. Some potters low fire glazes when they have to travel to another location to hire fire it and their results are fine.

 

I have a kiln load waiting to go but our temp here is over 100 and I can't bear the thought of the heat!

Cold snap coming next week ... Only 92 ... So i will fire then. : > )

I will time the firing to peak overnight in the hopes that power demand is down then.

I have a computer-controlled L&L kiln too, and it can handle a short-term power outage or a brownout. I once had a 20 minute power outage while firing, when the power came back on, the kiln just resumed firing. The control panel read "ErrP" and the current temperature alternately for the rest of the firing, just to let me know there had been an interruption to the power. If the power goes out for an extended time, the kiln will shut off and the control panel will read just "ErrP". If that happens during a bisque firing, I wouldn't worry at all, just refire the pots. For a glaze firing that depends. Some glazes and clays can be refired, but some won't be the same.

A spike in electricity, sometimes caused by lightning, can damage a digital controller. If the spike is severe enough, it can even burn out the elements along with televisions, computers, etc. That is why I unplug my computer at home during thunderstorms.
