For plaster and other terrain features, perhaps, standing the test of time see:

Thanks Golgotha!  That board looks almost as good as when he first made it.

What then are the advantages of dentist/synthetic plasters over resin for molding?

Dental plaster is very hard when dry….we used it a lot to cast Hirst Arts Bricks.  You needed to work them / carve them whilst still damp otherwise difficult when dry.

Cost, ease of use and chemical damage to moulds.  Resin tends to be harder and lighter.  You can extend the life of silicone moulds by using a good mould release with resin but the mould will still wear out faster than if you just use silicone.

One thing is that, for stonework, you can do a lot with various washes when on stonework where the resin needs certain paints to let you then use those techniques (The larger bottles of Applebarrel white craft paint, if applied unthinned, gives you a slightly chalky texture and it takes inks, washes, and stains much like plaster...it's already a very thin paint, but I've done that with a lot of things I wanted to look like stone). Plasters also work better for making a cohesive whole with some of the ground texture options such as the sculptamold or some of the patching compounds which work to blend it into other stone if you want something to look like it's carved from the stone there.

Cost, cost, cost, and mould durability.

Search for Raysin100, it's available throughout europe, should be also in UK!
I personally use Diplast, which is sold by a company in Rome.

Interesting. How is the weight? Heavy like plaster or lighter?
