I use a bowl that I got for $2 at Wal-Mart. However, I also picked up one of those desk-top mug-warmers on sale at CVS, and that does keep the lather wonderfully warm - the only problem is it's slightly too small to use the brush in effectively. I may see if I can find some stoneware I can use in the base.

So, how exactly does the scuttle work? You pour the hot water over the soap, where it goes down into the bottom to the brush?
