To get myself back in the groove, I was going to start project blog that required a bunch of blanks (bare nob-like ork torso/legs), so nothing too detailed, just a bunch of rough forms I can work from without having to build a new one from scratch for every mini.
So casting resin has an expiration date, nobody at the craft store told me this when I purchased it. Life got in the way of my hobby, but now I find myself with time to work on casting. It's the micromark cr-900 one-to-one resin, it's expired well over a year. They haven't been opened, they've been kept in bag in a cool dry place, it sounds like liquid in there, and it's not ridiculously humid here.
I can't really find much information online as to exactly what the drawbacks are to working with expired stuff. I heard it can discolor (which doesn't bother me), and the casting potlife is shorter and can trap more bubbles (these are blanks, a few bubbles isn't a problem). I'm more concerned if it won't set properly, or be gummy and ruin the mold.
Also how do you dispose of the stuff? do you just mix it regardless and throw out the unusable mass?
