i have been using a mug and soap puck ( d.r.harris) and when i make lather on my face for the first pass its nice and hot, because i soak the brush in hot water. but the second pass with the brush is cold. so is the purpose of a scuttle for only creams? and do you put the scuttle in the sink with the hot water? or do i have to get a scuttle sink, ha ha. and also who sells them. thanks:boohoo:
