Create a lot of smoke around 1000 F till it burns off the contaminates?
Someone gave me a board that they said they thought was the 1 inch thick hard fiberboard. It was putting out so much smoke at 1100 F that I turned it off as I was disconnecting the smoke detector.

You were on the right track. I'd fire it up as hot as you plan to use it. When it turns white it is ready to go. You are probably most of the way there. I usually leave Dodge while burning out the binders.

I have a piece of thick fibre board I cutup into a number of 1-foot kiln shelves. They work fine. But one of them is always grey after firing. I can vacuum the grey off to a certain extent, but it comes back. It doesn't seem to affect my firnings. I find this strange and possibly indicative of conspiracy. I'm also looking for divine images in the grey surface.

The problem with finding divine images would be that you can't fire the board again without losing the image. The other problem would be the pressing hordes of people drawn to your home and studio to see the said images.Don Burt wrote:I have a piece of thick fibre board I cutup into a number of 1-foot kiln shelves.

The black stuff really is finite and will disappear once totally burned out.
I wonder if you are any getting effects of a reduction firing. The burning carbon uses up oxygen in the kiln atmosphere.
