We also use Resin Rock, I have been using clear pro art die spacer from Ivoclar and it works great....See more It is always a good idea to exactly follow the manufacturers instructions regarding water to powder raitios because if you are using too much water it will change the density of the stone. So pretty much "that's what she said"

I agree with Melissa, the water ratio maybe too high. Dental die stone won't crumble unless the mixing...See more ratio is way off, mixing procedure is not correct, or the stone is not being properly stored. I would also check how long the stone sets.When I did models long ago I poured them the night before and in the morning I would have great detail and strong first pours to work with.
