One of the experiments I performed at the Vashon Island pit fire last month involved the use of steel wool as a fuming material. I was curious about steel wool because I had thought it was the cause for the beautiful colors on a very nice piece from my first pit firing back in 2002.

Well, I am still not sure — now that the experiment has been performed — if steel wool was behind the colors on that earlier piece, but as you can see in figure 1 above, the fuming of steel wool can certainly generate some truly wonderful color patterns on a receptive (i.e. terra sig coated and highly burnished) surface.
