The one I saw seemed to have a couple of layers and some airpockets between. It might have been a fairly heavy guage aluminum. It has been a long time since Mom showed me hers, and as I mentioned above, I usually just set anything that need to thaw on a cold cast iron skillet. $2 probably wasn't a bad price for the thing; (and by way of major thread creep) sometimes you can find real values at those dollar stores.

Rick, have you rounded up your equipment and ingredients yet? How is the fish?

SRS
