Here's all but 2 of the pieces I made. The other two got trashed because really they were total failures. All of the above pieces have flaws and only two are fixable. So this has turned out to be an epic learning experience. What did I learn?
1) don't work while in pain. see above.
2) prewarm resin for both pours, not just the first. 3 pieces ended up with massive bubbles due to not prewarming the resin on the second pour. The leftmost piece above was perfect except for the tiny cluster of bubbles along one edge. And check for bubbles every pour because they are fixable if caught soon enough.
3) Do fewer pieces at one time. One piece, the six pointed star, failed because the box that is supposed to keep the pieces from getting dust in the resin while curing got put directly on the edge of the piece rather than next to it which left some of the paper from the box on 2 of the points. Less crowding of the space by doing fewer pieces would have saved this one.
4) No plopping the pictures down on the resin. Lay them out from one edge toward the other so as not to trap air under them. The large oval and the pink square both had this as the only flaw. (I'm particularly unhappy about these failures as I already learned this lesson from marbling. Bad Liz! No keto cookies!)
5) Elevate the items so I can better see the doming when I'm doing the second pour. I overpoured several pieces, particularly the 2 I tossed. While some of this can be trimmed and filed off, it's still something that's easier to prevent than to fix.
6) Keep the temp up in the correct zone for the entire curing time. Two of the pieces have soft spots on the edges because of failure to cure correctly. (This also occurs if the resin mixing is not done properly but I don't believe that was the cause since both pieces were on the same side of the work table. I have a small heater on order to fix this.)
What good things came out of this work? I succeeded in using the 2 molds I made and they worked fine. I mixed colors, tested an idea about marbling, and learned some things about using the mandala transparencies with colors behind them. While I was incredibly frustrated right after unmolding things, I feel I learned a lot from the work. And James Clear's email today reminded me of some important things to keep in mind. His ideas today -
"If you haven’t started, then taking action is more important than finding a better strategy.
If you’re already taking action, then ensuring you’re working on the right thing is more important than working harder."
This is causing me to think about which part of the resin work is the right thing for me to be working on. If only life's lessons weren't so rough sometimes.
