I have that Norpro chiller. I ended up using it as a scuttle about three times. I found that the heat broke down the lather and I ended up just using the inner bowl as a lather bowl.
+1. Tried the bowel lathering all of about 3 times. I like the feed back from face lathering. Although, I must say the idea of a scuttle and warm later is appealing....then again that money could be shunted towards software....hmmm.
It'll get the job done, like the gravy boats, but they do tend to be a bit small, and really work better as brush warming scuttles than as lathering bowls.
Absolutely perfect for face-lathering.
