Calibrated mixing bowl?
I think that my ideal mixing bowl would be stoneware with calibrations marked on the inside so I could determine when a dough has doubled. I love the feel and ambiance of stoneware but I have a real problem estimating doubling with the bowl shape that is gradually increasing as the sides flare out. Currently I transfer my dough to a straight sided container that allows accurate observation of doubling. I suppose that I could use a clear glass bowl and make marks on the outside, but it is not the aesthetic that I yearn for. I have considered marking the inside of a stoneware bowl but I'm afraid that whatever I use will come off into the dough eventually and nobody wants that. I'm hoping one of you clever, experienced people will have some idea for me or know of a product. Thanks
