Hi Folks-
The kiln I use at my high school has never fired better- It came with =

school when it was built in 1992 and was there when I started in '94. It =

Kiln in Ca.- now sold off to a new company last year- .
The deal is the exterior sheet steel is in a declining state- it has c=

alarming- it is not internally vented - we have a large vent hood above t=

this point I am not worried about safety but I am approaching that realm =

The idea I am working with is finding someone who can weld some sheet =

the angle iron ( or is it steel) on the outside- covering the sheet that =

the way out, but not covering the angle iron- welding to its edge. This w=

So I am looking for ideas and feedback from folks who have been down t=
