  1. I high fire an earthenware clay (slipcasted). I open my top bung at 428F(220C), Front bung open at 392F (200C) and open door at 356F (180C). If I need to inspect a new piece, and I can get to it, I will remove it then.

    My friend works with porcelain. she opens her top bung at 572F (300C)

    No issues. Food safe , etc. Oh, and my friend can fire her kiln every 24 hours, should she want ... Quick ramp-up and down.

  2. Inya, I think that the bangle will shrink so much in the glaze firing, that it might fall off the supports. I would rather go for a very thin layer of glaze, rubbed off on both sides of the bangle, so that it looks like it has to be like that. or, just leave it unglazed. Sand with wet paper after a bisque firing and again after the 'glaze' firing. and add transfers.

  3. Ok, just to confuse you guys :-) I am going to use Celcius as measurement of temperature ...


    I leave my top bung hole open for a bisque firing till my kiln reaches 600C. this allows all moisture to evaporate, and make sure no damage to my elements. For a glaze firing, I keep it open to about 200C.


    If I am desperate to unpack a kiln, I will open the top bung at about 220C. And the door bung at about 180C.
