SC2 overfire and burnt inside

[Lee - Kilncare]

Hi Seahorse, sorry for the late reply, had a very well earned 2 weeks off.

You seem to be sorted but anyway here goes.
The colour of the "burning" says to me that it is actually not burning but binder residue from the bead door. Many hard insulations are held together with binders, these tend to burn out the first time they are heated. If the kiln doesn't go high enough then the residue remains on the surface or the cool sections until the temperature gets high enough to remove them completely and the insulation will go white again. Hence why it is recommended to leave the plug out for the first fire I'd guess.

And yes, the lower the temperature set, the higher the risk of overshoot as the kiln will be rising quickly at low temperatures and will not just stop when the controller says so. Think of it as trying to stop a ship, you tell it wow....but the ship says no! The faster it goes, the more it drifts on.
To avoid overshoot, just put a value of climb in for the controller to work to.

Thanks Colette, Dawn, Pat and Lee for your further thoughts,

It seems that my new SC2 does let you program in degrees C or Degrees F - but for some reason my brain can only cope with degrees C . I think I'm a metric girl at heart.

Thank you Lee for the useful explanation for the burning.

I'm happy to say, my kiln seems to be functioning and looking fine now. I've also managed to complete my first semi-successful attempt at fusing in it (pics posted in the fusing section).

Thanks again

Best wishes

Sam

Sam, I am the same, I simply cannot get to grips with fahrenheit at all - even though I'm imperial with almost every other measurement!  Freezing at O degrees just makes sense!

Yes me too, 0 degrees C works for me! Don't you just hate it when folk start talking about 56F - uh wot's that then?
