I have asthma, so I really dont want anything to do with resins. Will these types of (gypsum???) materials work ok for 10mm buildings? I'm thinking of painting latex onto a building I made and then pouring a plaster-type material into the latex mold. Plaster of Paris is too soft. Thanx. |

Yes, they'll do the job just fine – hydrocal or dental plaster are both first rate – I haven't tried crystalcal. |

link Here's a good resource for product reviews and casting tips. You'll find the difference between dental plaster and plaster of paris is immense. |

Use hydrocal not dental plaster. Dental plaster is more expensive and sets too fast, often the material does not flow well into the mold before it sets. Use Rit or other clothing dye to color the water and your plaster will be colored rather than white. White plaster can be hard to paint. I am not sure the dust from plaster will be better for you than the fumes from resin. Check with the manufacturer and your doctor. Some resins, like those from Smoothon have very few fumes. YMMV.

Thanx everybody, like the idea of Hydrocal. JezEger that link is superb! |

By your Hydrocal from a local hardware store, not a model shop. It's a lot cheaper. Mike Bunkermeister Creek
