I am assuming you are using the Ultracal alternative for casting latex masks or other items?

If yes, then dont worry so much about how tough a material you need. What you need to look for is a Porous (spellcheck) material.
The ultracal30 is best becuase A. It absorbs water due to it nature. and B. It is super strong meaning the detail and such lasts longer.

Keep this in mind when looking for a material. It needs to be able to absorb water From latex, leaving you the negative from the mold.

I know that Dental Plaster is used in miniatures a lot.

If I'm reading this right, Dental plaster is a Hydrocal. I use a Hydrocal because I don't have a local source for Ultracal 30. Hydrocal can have a lot of different additives to it to act different when needed. The different versions would have different dwell times because they will obsorb water at different rates.

But if it has a plastic in it, it won't work well. It won't soak up the moisture from the latex.

I think if you wanted to use it you might want to get a small batch to test it. It may work.
