Gloves and long sleeves are a good idea, just like working with fiberglass insulation. I even took my clothes off in the garage and threw them straight into the wash by themselves because I didn't want any loose ceramic fibers around my kids. Might be a little overboard, then again I might not.
The only refractory for coating that I am familiar with is ITC-100, designed for the ceramics industry as a coating for the inside of kilns. You just paint it on with a brush or it can be used in a sprayer. A search of ceramics supply houses might turn you up some, but I got mine from Jay Hayes. There is a link to his email and web site from Ron Reil's site. If you look under my post for my "Mini-forge inferno!" you will find the link to Ron Reil's site. I think satanite can also be used but I was under the impression that it was more of a mortar type consistency. The ITC-100 is expensive, around $24.00 for a pint and I only needed half a pint to coat my freon tank mini-forge. There must be other coatings that can be used though. -Guy Thomas
