I had a cabinet door handle drop on the edge of my glass cooktop and put a bullseye type divot on the edge of the top. I'm wondering if there is anyway to repair, or fill-in, the divot. It is black glass still.
I would use a windshield repair kit.
I think you will find that almost all sites will say these cannot or should not be repaired but should be replaced.
That said; there are lots of products on the market that advertise their product can be used for this.
If you decide to use one of these products be sure you disconnect the stove before doing anything and follow closely every detail of the instructions.

I totally agree that replacement is the best for safety reasons. I am all about fixing things when it is safe, but something that is used so often and with heat, best to replace!
They do sell window glass repair kits for cars that do work and people fix small cracks in their windows all the time. Considering this isn't your car and it is your tabletop I think this can work. Most people say not to repair them but to replace them.
My worry with this is that the repair kit might not be able to handle the hot temperature when the oven is used.
I broke my flattop glass stove one time but it needed to be replaced. As we had inherited the stove when we moved in years before, we just replaced the entire stove.
Good luck and let us know how it turns out.
This is a page about repairing scratches on a glass top stove. Usually easier to keep clean than a conventional range, scratches can mar the glass surface.
If the glass top on your range breaks there are really only two options. One is to buy a whole new stove, secondly you can try to replace just the top.
