I would love to hear from anyone who has used this casting material and if at all possible to see some examples of the end results

Re: jesomite? anyone ever used it?

didnt know it still existed.... a plaster plasticiser, great strength, considered odourless, safe, casts well, sets with the plaster [often used with herculite or one of the stronger plasters], can apply like polyester resin, brushed on with fibreglass, sandable, colourable [although this slightly weakens it] does what it says on the instructions.
its a functional medium. wish i could get it here.

Re: jesomite? anyone ever used it?

I used to use it quite a bit... personally I don't think it's suitable for casting thin or finely detailed sections as it can damage easily, it can be a bit fragile. I'm talking about sections no thinner than 15 - 20mm, even then I'd be wary of it. It does take detail well but again if its fine detail it can easily be damaged. As with a lot of materials it's great for certain uses. I think you can get glass reinforcements but I'm not sure what effect it might have if you wanted to work on it once cast.

I've used it mainly as you would if you fibreglassed something, laying it up with scrim, fibreglass mating or tissue, material etc. I used it for scenic work, as it's fairly inert it's great for layering over polystyrene from which you carve the basic structure and the final layer of jesmonite can be sanded smooth or textured, painted etc. It's solvent free so less harmful than some things you can use. A lot of architectural repairers use it.

You tend to get it as a 2 part pack, a powder and a resin liquid, but you can get tints for it as well. It's a nice material to work with, you just need to know it's limitations as with any material.
