Bowl latherer here. And enjoying it. I got my Schwarzweisskeramik scuttle last week and it's something to get used to, but it works quite nicely in getting me nice warm lather.

I think one might say I halfways face lather anyway, because, although I create the thick stuff in the scuttle/mug/bowl, I put a lot of action on my face with the brush too. A big fan of Seraphim's mayo too.
