Thanks guys! I've been having a lot of fun with it! Those little suction cups are tiny but they were fun to do.
Apoxie Sculpt is epic and so much better than Sculpty which is porous and breaks *so* easily, this stuff turns to steel. It's also non-toxic and water proof so you can use it in aquariums and reptile habitats.
It's a two part clay that you mix 50/50. The cure time is highly temp dependent. In a room about 65 degrees it takes 4-5 hours to cure completely, it is very wet and sticky for 30 mins, takes some form in 60 mines, accepts detail for another hour, then needs to be left alone. You can not really slow it down other than making it colder so you have to have a plan when you work with it. It sands very easily and smoothly. I do my work in stages to prevent it from curing on me while I'm working on detail. However it also sticks to itself very well so you can add new wet to dry clay. It smooths out nicely with water when wet and sand paper when dry.
If you put it in the oven at 250 for 5 mins it will harden like a rock (but becareful because it gets softer before it gets harder this way so you need to make sure the clay is supported to keep it from collapsing. If you take it hot out of the oven and pour cold running water over it you can get some cool bumpy patterns in it.
