kiln lid material
Posted: Tue Aug 12, 2003 8:43 am
I'm building a bigger, better, faster kiln, and am taking stock on some of the materials. The walls and floor are brick, and the lid is a ceramic composite board called M board. On the inside of this is a layer of refrasil, Irish Linen, and then there will be 6 elements hanging from the lid.
When placing the refrasil into the angle iron frame yesterday, I noticed it was not as big as I had wanted....there was just a slight overap after the M board, and it did not tuck into the angle iron more than an inch or so.
I put some white syrupy kiln repairing material onto the refrasil, and hope it will let the refrasil stay in place. Any suggestions on attaching refrasil to either the M board, or the angle iron?
Also, when placing the M board, which was in two pieces, into the lid, a chunk of the material broke. It was a 2 inch board, and at this seam, it was cut to 1 inch on the top, and 1 inch on the bottom, to lay into each other. The bottom piece is intact, and I put the top "crumbs" back in place. Seeing as this is my only insulation, other than the refrasil, in the lid, should I start with another piece, or is there a better material for the lid that I should use instead? Or will the damage not hurt the overall needs of the kiln.
