Hello all.

The edge of my ceramic/ glass gas cooktop has chipped/ cracked - can it be repaired? It's small but left sharp, jagged edges but doesn't interfere with the burners. I'd like to avoid replacing the whole pane of glass if possible especially since it's no longer available/ in production. Photo here- https://imgur.com/a/dMApaj9

What should I know about such chips/ cracks if left unrepaired/ unfixed?

Are there any ways/ options to fix it or is replacing the only options & if replacing is the only option then why is that? Why can such things not be fixed?

Just trying to understand this a bit before I can make an informed decision on how to proceed. Thank you!

You can probably fill it in with a high temperature epoxy.

I did see this too. But I am seeing mixed responses on if these repair kits/ epoxies should be used at all. Of course, it is easier for the usual repair people to suggest replacing the glass top & maybe that is safer & required too but I want to make sure I am not making a big deal of a small crack/ taken for a ride but also want to be safe.

You can wet sand the edge to remove the ability to cut/stab and then use the high temp epoxy. The cracking leading toward the burners is pretty much just aesthetic at that point and if it does grow in future, you can decide on replacing it. Functionality you shouldn't have any issues.

Start at like an 80-120 grit wet sandpaper and work your way up to 2000 or so. Shouldnt take too long for that small edge.

Tip for the edge when doing epoxy. You can use a cut up soda can to wedge under and bend up straight to get a nice edge. Lube it with a super fine layer of grease to prevent any sticking. Finish by wet sanding again to get the same rounded edge back and level it best you can. Will it be perfect? Nope, but its perfectly functional.

Fatzilla is spot on.

This looks like just an edge chip, and all you're really doing here is filling it in like a rock chip in a car windshield to smooth it out and maybe prevent more cracking. It should be fine.

And if it makes you feel better, my grandmother has a ceramic cooktop that has had a crack across the entire thing for as long as I can remember, and it works just fine and her house hasn't burned down yet.
