What's the composition for jewelers' investment? Boy, there was an era, back in the day, when I spent way too much time thinking about plaster composition, heh. I wound up concluding that it was best to switch over to dental plaster for leafcutter ant nests - hard enough that they can't chew through it, but still porous enough that it will hold enough moisture to keep their fungus gardens happy. I've also just mixed plaster of paris with hydrostone, as another option.
