Found a small crack in my new glass

[Jason Scott]

I just pulled a bow blank out of the hot box last night. After I cleaned it up and pulled the tape off it I found what appears to be a small, single, hairline crack that wiggles its way from near the tip on one limb to the center of the riser. It's on the back of a one piece longbow with black glass. The crack is not a straight line crack like from moisture swelling and shrinking that I have seen before. It looks sort of like a lightning bolt, like an electric current type of shape that changes direction abruptly and often. It does not run off the side, just stays mainly in the middle and I can't tell if it's just a surface blem or goes all the way through. I don't have pics yet and I'm not sure it would even be seen in a pic but I will try when I get home to post one. Has anyone ever seen small squiggly cracks in glass before? I went ahead and put tip overlays on it and will finish it but dang, what a bummer. We'll see what happens.

Never seen squiggly cracks,thats a new one on me!
I hate when that kind of stuff shows up,especially when you have that much time and effort already invested!!

It might make a good bow for snake skins.

Never heard of glass cracking like,because the fibers run parallel.You try sanding with 220 and see
if it is on the surface.

Hope it was just a surface blem. It looked a little as if two dissimilar materials were poured together and that was where they met. Maybe like if you poured new concrete to patch a hole in an old slab and you can see where the materials mate up. Thanks guys. Anyway, I sanded and sprayed the finish and I can not see it anymore. Before I finished it I really tested it well on the tiller tree and did'nt notice any noises and it didn't grow or change shape.

It has over 150 shots on it by now and I can't tell that it ever had the blem in the glass. I should have several hundred after this weekend.
