Scratch or crack?

[supercoolname]

This is in the curved glass corner of my BioCube, a few inches from the top. With the naked eye it looks like it’s fracturing, but I don’t know if that’s even possible. The photos look more like scratches to me (or snail trails, but it’s not), but I’m not sure how they could’ve gotten there. I’ve never scratched any glass like that before, especially not with the flipper nano.

Does anyone have any experience with curved (or any) glass cracking like this?

Looks like scratches. Graze your fingernail over it. If it’s a crack it will feel like a clean cut
