Why Is My Boiling Pot Turned Black?

The boiling pot turns black due to the patina effect. When we boil water that contains a high amount of minerals in the pot, minerals present in water react with heat. 

As a result, your pot turns black with time. This reaction is called the patina effect. This reaction mostly affects the aluminum pots.

Are you also worried about the blackening of your boiling pot? You shouldn’t worry about that because it is a very common reaction between minerals and heat.

When aluminium comes into contact with food that contains salt, is very acidic or spicy, or contains vinegar, those black specks that you can see are the result.

You can consume food that has been cooked with aluminium because it isn’t dangerous.

You can get all the information regarding the blackening process that occurs in a boiling pot after reading this article.

Reasons For Blackening Of Boiling Pot:

Many factors can play a part in the blackening of the boiling pot. The major three culprits play their role in this crime.

  1. Heat 
  2. Minerals And Impurities Of Water
  3. Strong Dishwasher

Heat:

Heat plays a major role in the blackening of a boiling pot. If the heat is too high or your stove is not evenly distributing the heat, both can be the reasons for the blackening of the boiling pot. Heat increases the blackening reaction.

Minerals And Impurities:

When you use water that contains a high amount of minerals for boiling in a pot consequently the reaction between minerals and heat occurs which becomes the reason for this blackening activity. 

We are living in an era in which everything is polluted. The water which we mostly use for cooking is also not safe. 

It contains impurities like calcium, magnesium, etc. When we use this polluted water to boil in a pot. 

Calcium and magnesium start to settle in the bottom of the boiling pot as a residue. These residues make a black layer which gives a dark color to boiling pots.

Strong Dishwasher:

The strong alkaline dishwasher can also trigger the patina effect acting as the third culprit for the blackening of boiling pot.

Safety Measures To Avoid Blackening:

The blackening of the boiling pot is a natural process. You can’t totally remove it but you can slow the blackening process by taking safety measures.

  1. Use high-quality cookware that evenly distributes the heat.
  2. Keep the stove temperature low.
  3. Avoid using a strong alkaline dishwasher because it triggers the reaction.
  4. Use filter water to boil in the pot because it has fewer impurities and minerals that take part in the reaction of blackening of the boiling pot.
