The edge of my ceramic/ glass gas cooktop has chipped/ cracked - can it be repaired? It 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.

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.
