I'm looking for a detailed hard casting plaster, like Ultracal or Hydrocal. However I can't find a distributor of these two in Europe (England, Germany...) Besides some overlypriced bags, sold by individuals on Amazon (however they usually have only one or two bags).
Is there an alternative to these Materials that Europeans use? Because I can hardly imagine that they don't make plaster/stone castings.
I've heard, that you could use something like dental plaster.
