This is how things are supposed to work. So, don’t be surprised if you notice one of your favorite products starts wearing out. Items in the kitchen, too, are reactive to constant use. For instance, a cast iron pan can crack after some time. Many people don’t know the reasons this is happening.

However, in this post, we take you through the revelation of how cast-iron pan cracks. We also recognize that it is okay and more economical to fix things. That is why we go a little bit further to tell you how to fix the cracked pans. We ask you to sit back and enjoy the ride.

What Causes a Cast Iron Pan to Crack?

You might have noticed that your cast iron pan is beginning to show signs of cracks. And you are worried about it. One thing you need to know is that you are not the only one experiencing it. So, relax. There are thousands of other people passing through the same thing. 

The problem then should not be about you noticing a crack. Instead, it should be about you knowing what causes it. And, further, how you can fix the cracked pan. 

First, we bring you the causes. In other words, what are the things that can cause a cast iron pan to crack?

1. Acidic Foods

One major reason for the cracks is constantly boiling foods that are high in acidic content in them. The reality is that these acidic contents weaken your pans and make them susceptible to cracking. As such, if you are to guard against any crack, you need to avoid boiling acidic foods.

In case you didn’t know, one of the highlights of the cast iron is that manufacturers season it. Even if they don’t, you can season them. So, the problem is now with the seasoning. If you cook acidic foods, it can wear out the seasoning.

When this happens, your foods will burn easily, further damaging the cast iron pan’s interior. So, it is better to say no to any acidic content in your pans.

2. Thermal Shocks

Another major thing that can happen to your cast iron pan and make it crack is thermal shock. Many people do not understand what this means, so we will briefly take you through it. 

The thermal shock has to do with a rapid temperature change. This rapid temperature change can cause the cast iron to want to expand. And this can result in a crack. So, the way it works and happens is simple. If your cast iron pan has previously been hot and you suddenly pour iced water in it. This is a straightforward example of how a cast iron pan can crack so easily. 

If, after the crack, you keep putting it in a position, it can experience thermal shock; then, the worst can happen. One day, you may have your iron pan in your hands in two due to a break. 

3. Excessive High Temperature

Asides from this, it is better to introduce the heat to the cast iron pan slowly. This, of course, is to prevent sudden heat that can cause thermal shock. Ideally, manufacturers have written the maximum heat the iron cast can withstand to prevent a crack.

We expect you to follow this religiously. In the rare case that you have lost the iron cast manual, you can still maintain your pan. The first thing is to ensure that you slowly introduce heat to the pan. And after cooking, you allow it cool if you want to put it at the opposite temperature. 

We would advise that the temperature you would introduce to your iron pan should not be more than 500 degrees. This is the maximum you should go at any given time to prevent your pan from cracking.

So, that is how cracks happen to your cast iron pan. 

Though this is bad enough, it isn’t the end. The exciting thing is that you can always make amends. Yes, you can fix your iron pans and get to use them again. If you are wondering how you can do this, read further. We have covered everything for you.
