shawnhar Posted November 26, 2018 Report Share Posted November 26, 2018 I have my TC offset to compensate quite a bit, even though it is a new thermocouple (less than 10 glaze firings) and I am wondering what will happen when I get new elements. I think I have at least a dozen or so firings out of the current elements but I think they will need to be replaced in a couple of months as I plan to start firing twice a week now that i have the glaze fire worked out. Does the TC offset change with new elements? Link to comment Share on other sites More sharing options...
JohnnyK Posted November 26, 2018 Report Share Posted November 26, 2018 My guess would be that since the TC measures heat in the kiln that your offset shouldn't be affected by more efficient new elements. If you were replacing the TC, that would be a different story... JohnnyK Link to comment Share on other sites More sharing options...

Babs Posted November 27, 2018 Report Share Posted November 27, 2018 Shouldn'tneed new elements yet.....are your firings slowing down?? What makes you think you need new elements? Link to comment Share on other sites More sharing options...
liambesaw Posted November 27, 2018 Report Share Posted November 27, 2018 Yeah even firing twice a week should last a year or more, right? Link to comment Share on other sites More sharing options...
shawnhar Posted November 28, 2018 Author Report Share Posted November 28, 2018 I read somewhere you only get 50 (ish) glaze firings out of a set of elements, is that inaccurate? At twice a week that would be over 100 in a year, plus the bisque. I am not seeing increase in firing time really, I think 9 minutes is probably within the variance and the last 2 were exactly the same Link to comment Share on other sites More sharing options...

shawnhar Posted November 28, 2018 Author Report Share Posted November 28, 2018 Thanks Neil, guess I won't worry about the elements for a while. I have no idea how many times they were fired when I got the kiln but they looked really good and still do. Link to comment Share on other sites More sharing options...

Any basic cheap digital multi-meter form the hardware store will work. Once the elements are 10% off from original they should be replaced.
