Glass cooktops are sleek.
They’re modern.
They wipe clean in seconds.
But beneath that smooth, glossy surface lies something surprisingly fragile.
And one simple mistake — one you might not even realize is dangerous — can cause your stovetop to crack or shatter unexpectedly, sometimes with startling force.
No warning.
No second chance.
Just a spiderweb of cracks across your stove — and possibly glass shards on your kitchen floor.
Let’s talk about the #1 mistake that causes this — how to avoid it — and what else you should know to protect your kitchen (and your safety).
Because real beauty isn’t just in how it looks…
it’s in how safely it works.
❌ The #1 Mistake: Using Warped or Damaged Cookware
Yes — a bent or uneven pan bottom is the most common reason glass stoves fail.
Here’s why:
🔍 How It Happens
When a pot or pan has a warped base, it doesn’t sit flat on the cooktop
Heat builds up under the raised edges, creating uneven thermal stress
Over time — or suddenly — the glass can crack from the pressure
Even worse? Some pans (like older cast iron or cheap stainless steel) expand when hot, worsening the gap between metal and glass.
💥 Result: A loud pop… then a cracked or shattered cooktop.
