Here’s What Happens:
You lift a hot lid from a boiling pot or pan.
You place it — flat side down — on the glass stove.
The lid creates a vacuum seal with the surface.
Heat gets trapped in that tiny pocket between the lid and the glass.
The glass heats unevenly — and shatters under pressure .
This isn’t just anecdotal.
It’s thermal stress — a known issue with ceramic-glass cooktops.
Glass expands when hot — and contracts when cold.
When one spot gets too hot too fast ?
Cracks and shatters happen.
And once that glass is cracked?
You’re not just looking at a $200 fix.
You’re looking at $500–$1,000+ to replace the entire cooktop.
