Is there any way to make the shave soap hot? I soak the brush in hot water while in the shower and allow a few drops of water to soak into the soap cake too. Out of the shower and immediately start making lather and when it all gets to my face its cold... This was only my second time to make lather but I got better at making it, had tons more volume out of it.

Can't tell what soap it is, vintage I am sure. Was in the mug I inherited from my grandfather last week.

Stupid question... Is the mug for making lather in or just to hold the soap? I tried making lather in a bowl the other day but lastnight I made lather IN the mug and had much better results
