Cannot do that if shaving with running water.
And the problem with light weight ceramic bowls is that they break in pieces when slip from the hand and fall down. :cry:
That's why I prefer the Schwarzweisskeramik. Its keeps the lather warm, leaves the sink alone and it doesn't slip your hand easily because it is heavy and you need a steady grasp to move it. And even if it falls down, most likely it won't break because it is a really heavy duty scuttle. :medvl:
