Vintage Sawtooth Crock Bowl

Recently I was using a crock bowl much like this to mix sourdough while a friend was over. She commented that she doesn't use hers, but has them displayed in her hutch. These pieces of art are lovely stacked, being used to mix in or displayed on a shelf. The history of all the hands that have used these crock bowls, that's the real story. Let's add to the history.
