Not bathing but drowning

An aspect of my FMP installation is to have a ceramic sculpture with a head drowning/ submerged in a bowl of water.

I had initially planned to create a silicone jacket mould of my own face to do so. 

But then I found these slip casts in the ceramics studio!!!! So I'm using these to save time. Winner winner clay head children dinner.

After chatting with the ceramics technician it sounds like throwing my own bowl (well) is unrealistic at best. So I can either commission him to throw one for me or I can use a found object.
