The company that supplied the silicon and plaster also has a few other poring media, so I've bought some resins. I've opted for Poly Urethane and got me a test kit of Acrylate in it as well.
The whole process is more or less the same as using plaster. Measuring and accurately weighing the individual components and making sure everything is ready and set. Cos of the short pot-life you only have a few minutes to poor.
I'll cast a few more and once they'll finished they will go on offer.
