If I wish to create my lather directly in my scuttle, should i go with the GP scuttle, the small moss, or the large moss scuttle. I have a vulfix 2234 brush with a 22 mm knot and a 50 mm brush loft.

Currently i use a very large mug, 4.5 inches wide and 3.5 inches deep and this is way to big. I want a scuttle to keep the lather nice and warm and to free up sink room.

Also can boiling water be poured into the scuttle, my tap water is not that hot...or perhaps would water just under boiling temp be best.

Thanks alot for any opinions...
