Voila!! I had recently set my Tree of Life fused glass plate aside, adding it to the pile that I had yet to photograph. I really love the aventurine green with the iridescent amber and swirly opal green/white glass. The colors are beautiful, reminiscent of summer, and make me want to do an entire series of winter, spring, summer and fall tree plates.
However....
when my wonderful fiance was tidying the house (and organizing my piles, he really is incredibly sweet), he noticed this crack in the plate. Now, I don't know if it's the weather, or if it's just that time in my life when I get to learn about stress and glass, but instead of throwing the blame on him (He must've dropped something on it, right?), I somehow knew that I had another stress case!
But, how exactly would I know? It surely doesn't look like a case of incompatible glass. Look at that S-curve that doesn't follow any seams. It runs right through the middle of at least three pieces of glass (which are all different colors). Reference this link for a wonderfully, hideous picture of incompatible glass.
Aha! My first chance to use the polarizing lenses that have been sitting in the studio, just waiting to confirm my suspicions...
Whoa, Nelly!! Just look at that stress!!! I've been told that after a stress break, you can no longer see the stress halo when the piece is placed between the polarized lenses. Well, if that's true, then just imagine the halo that was apparent before this fracture.
So, what to do now? I'm going to put my poor little tree back in the kiln. Yup, throwing her back in. I'm gonna slowly go up to 1250 F and bring down the edges, then go up to 1480 F again to fuse the crack back together. But, this time, I'm slowing down the annealing schedule and holding for a bit longer, because that, I think was the culprit. I used the smaller kiln (Paragon Fusion7), and did not hold my poor plate at 1050 F for long enough.
Hopefully, that will solve my problem, 'cuz I'm getting tired of seeing breaks:(
