"Dutch Oven"/Resin Casting

I've been playing around with resin to see what more I can do with it as a media. Nothing is fully formed, just a number of test pieces that have some promise but a few problems such as bubbles or breaks. Anyway, I built this hotbox out of some scraps I had laying around plus a reptile tank heater. I had to build it since resin requires a temp between 70-85 degrees F in order to cure which is an issue in a studio in MN kept between 45-60 degrees. Anyway, I'm hoping to learn enough in these small experiments to do something much larger and more complex down the road.
