Why Do Induction Hobs Crack?

If your induction hob has cracked, then I am sure you may be wondering why. You’re also probably wondering whether your induction hob is safe to use.

Well, I am here to answer these induction hob questions and a few more.

Let’s first tackle why your induction hob may have cracked.


Why Do Induction Hobs Crack?

Induction hobs can be prone to cracking if they are not taken care of properly. Unlike gas hobs, induction hobs are a bit more brittle.

Now, induction hobs can certainly stand up to a lot of use, but if they aren’t taken care of, cracks can form.

1. Incorrect or poorly made cookware

Certain types of cookware can damage your induction hob. Well, sort of. To be more precise, badly made cookware can damage your induction hob.

If there are rough edges on the bottom of your cookware, these can damage your hob.

Also, cookware such as ceramic, stone, porcelain and cast iron are not recommended on glass-topped hobs. These can form scratches and can weaken the glass and cause cracks. You need to use the right pans for an induction hob to keep it crack-free.


2. Dropping cookware

This is one of the biggest causes of cracks in induction hobs.

Glass cooktops are very vulnerable to impact damage. If you drop cookware onto your induction hob and it lands on its edge, this will likely cause a crack.

However, even when cookware lands on an induction hob bottom-first, that can still cause a crack if it is heavy enough.


3. Temperature shock

If you have been using a pan in your oven and the induction hob is not heated up, do not put the pan on the hob. This can create a thermal shock and may cause the glass to crack.

You also want to choose the correct ring for the size of pan you are using. If you use a ring that is too small, the heat from the pan can overheat the surface and crack it.

Do Induction Hobs Crack Easily?

In some ways, yes. Induction hobs certainly crack more easily than a gas hob, but they are pretty hardy as long as you take care of them.

If you are careful to not drop anything on your induction hob and do not cause any thermal shocks, your induction hob will live a long life.


Cracked Induction Hob Repair

A crack in an induction hob is not really repairable. Instead, you will need to replace the whole of the glass top.

There are replacement induction hob tops available, and it is best to go to the manufacturer of your induction hob for this replacement. The rough cost (and this is extremely rough) is about a third of the cost of your induction hob.


Is It Safe to Use a Cracked Glass Cooktop?

No, you shouldn’t use your hob if it has a crack in it. Switch the hob off at the mains and seek a replacement. Any cracks in a hob can cause electrocution because of the wring being exposed to water and stuff.

Even water in the air from cooking may mean that your induction hob is suddenly extremely dangerous. So, be safe, do not use your induction hob and seek replacement glass.


Can a Cracked Ceramic Hob Be Repaired?

Again, a cracked ceramic hob cannot be repaired. Instead, it is safer to look for a replacement (see the best ceramic hobs here).

Just like an induction hob, the threat of electrocution is ever-present, and you don’t know how much damage the guts of your hob have taken. So, it isn’t worth risking using a ceramic hob if it has a crack or a chip, it will need to be replaced.



I hope this look at induction hob and ceramic hob cracks has been helpful. I know that it is inconvenient to be without your induction hob, but it is far safer to stop using a cracked one and seek a replacement.
