Plaster Moulds Release Agents

Useful info..TY

thanks, chilly, i have a ZAKI DESIGN melamine plastic bowl that is too good to lose if the plaster sticks to it.  now i believe i will make a mold from its interior.  it is almost spherical and i can see using the hump it will produce in a lot of ways.

#OldLady  I've made hump moulds from plastic mixing bowls.  The plaster has always just slid out, but if you want to be sure, no harm in using soapy release or cling film.

Good Luck.
