Underfiring..?

Recommended Posts

So...yeah. Fred's underfiring. I have no idea WHY this is happening or HOW, since the pyrometric cones have to be at a 90-degree angle before tripping, right? Sadly, mine are more like a clock's hands that say 9:08. Is it that I'm positioning the cone wrong? What could be causing this? :'(

How long is the distance from your kiln to the electric circuit?  In an earlier post, you mentioned using a heavy duty extension cord.  You lose power the longer the distance it has to travel from the circuit box to the kiln.  My guess is you are not getting full power due to distance.

The power situation could prevent the kiln from reaching temperature, but if the cone is bending and the sitter is shutting it off, then the power is not an issue.

Ohhhhhhh...you know, you just might be right. It's about a 12ft cord--it was the cord that used to go directly into the power box in my old place, but was modified because the power box was 10ft further than the original cord could stretch. Agh geez...

Whoops! :D Guess not. :)

Neil, uh...how do I calibrate my sitter?
