I am new to the casting madness but have been bitten by the bug by trying some clearcast over labels. A quick question for the experienced casters, does it matter what type of plastic cup you use to mix your resin? Can I use the thin water cooler cups, as the resin will only be in them for a short while before going into the mould, or is there still a risk of reaction/melting even at such an early stage?
Thanks in advance
Chris
