Hi,
Sorry I don't have the original post -- how to make a mold of a roasting
pan to dry clay in.
My understanding is that mold soap (same thing, I think) has the purpose of
filling in the microscopic irregularities and blocking the porosity of
plaster model surfaces.
If you're molding a metal or glass item like a roasting pan, green soap
shouldn't be required, since the model is not absorbent. I'd apply any old
release -- aerosol cooking oil, a thin coat of petrojelly, Murphy's oil
soap -- wipe off well and go for the gusto. If the draft is okay, I'll bet
my 2 cents cash you shall be released.
Jeff

Alas & alack, I too thought Murphy's soap would be okay to release plaster
from a pyrex baking dish - well, I now have lovely shards of my favorite
pyrex dish!
