Some where in these forums I read of filling 2 bowls with hot water. Once both bowls are heated up you dump the water from the bowl you'll make the lather in. The other you dump out enough water so it does not over flow when you put your lathering bowl in it to stay warm.
I tried it this morning and the lather was toasty warm for the 2nd shave. Neat trick.
I see a pottery scuttle for sale at Straight Razor Designs. Looks like it does the same thing. Has anyone tried it?
I'm just 5 full shaves into the straight razor so still lots to learn.
