I use hydrocal instead of plaster, its available from most lumber
yards or dental supply comp. There is also an additive, the name
escapes now but I've seen it in the*** Blick art supply catalog. You
can also try dipping the casting in shelac. This penetrates the
plaster sealing and strengthing it.
