I'm trying to only use materials that came in my RJM box. Here I'm annealing and rolling out a casting sprue to use as some much needed sheet. Again thinking about if a future artist will be able to use these pieces for future work by dismantling them I can only think of course they can. I love metal just for that reason, it can be cut, soldered, and refined a limitless amount of times. A casting sprue can become sheet and that sheet and any other scraps in turn can used for casting. It's a beautiful metals circle of life!
