Can you possibly glue the mold that has "died" together with white glue and
tape to make one last casting? If you can, the job will be kuch
easier. If it is a two piece mold then make the casting, remove one piece
of the mold, and then soap the plaster faces of the mold with the piece
still in place and make another mold piece. Then repeat with other side.

You need FRESH casting plaster, look in archives there is alot of
information already there.

Here is an old post of mine about my method:

Eleanora's EZ Breasy Plaster Casting Method.
Having no patience at all with the weighing of water I do it in
the following manner:
1. Judge volume of pour (if you keep a log of your pours it will help).
2. Volume of plaster desired = volume of dry plaster. Only FRESH #1
pottery plaster should be used. Know your source. Ask how long the bags
have been around.
3. Volume of water = 2/3 volume of dry plaster.
so. measure your water and pour it in a container large enough. Dump
plaster in and mix for afew minutes. When it's thickened like cream it's
ready. When it's thickened like pudding it's more than ready.

Hope this helps.Eleanora
