Last Updated on April 23, 2023 by Lauren Beck

Have you ever wondered if you can put hot oil in glass? Maybe you’ve got some leftover cooking oil or need to transfer some hot oil from a pot to a container. The last thing you want is to shatter the glass or cause any accidents. 

In this article, we’ll answer your questions and give you some tips on how to handle hot oil safely.

Can You Put Hot Oil in Glass?

The short answer is, it depends on the type of glass. Some glass containers are made to withstand high temperatures, while others are not. 

If you’re not sure if your glass container can handle hot oil, it’s best to err on the side of caution and avoid using it.

Does Glass Jar Break in Heat?

Yes, glass jars can break when exposed to sudden changes in temperature, especially if they’re not designed to handle hot liquids. 

When you pour hot oil into a glass jar that’s not designed for it, the heat can cause the glass to expand quickly, which can lead to cracks or shattering. This is why it’s important to use containers that are specifically designed for holding hot liquids.

Can You Pour Hot Oil Into a Mason Jar?

Mason jars are not typically designed to handle hot liquids, so pouring hot oil into one is not recommended. 

However, some brands of mason jars are made with tempered glass that can withstand high temperatures. Check the label or manufacturer’s website to see if your mason jar is suitable for hot liquids.

Can I Put Hot Oil in a Plastic Container?

It’s generally not recommended to put hot oil in a plastic container because the heat can cause the plastic to melt or release harmful chemicals into the oil. 

If you must use a plastic container, make sure it’s made of heat-resistant materials and specifically designed for hot liquids.

Can You Put Hot Oil in a Ceramic Bowl?

Ceramic bowls are usually safe for holding hot liquids, but it’s best to check the manufacturer’s instructions to be sure. Some types of ceramic may crack or shatter if exposed to sudden changes in temperature, so it’s important to handle them with care.

Can You Pour Hot Oil Into Pyrex?

Pyrex is a type of heat-resistant glass that’s designed to withstand high temperatures. Pouring hot oil into Pyrex containers is safe as long as they’re not damaged or chipped. 

However, it’s still a good idea to handle hot oil with care and avoid sudden temperature changes.

Do You Keep Hot Cooking Oil in the Fridge?

No, you should never put hot cooking oil in the fridge. Putting hot oil in the fridge can cause it to solidify and create a mess or clog your pipes. Instead, let the oil cool down to room temperature before storing it in an airtight container.

Ways to Dispose of Cooking Grease

Properly disposing of cooking grease is important for preventing clogs in your pipes and avoiding harm to the environment [1]. Here are some ways to dispose of cooking grease:

  • Pour the cooled grease into a sealable container and throw it in the trash.
  • Mix the cooled grease with cat litter or sawdust before throwing it away.
  • Take the cooled grease to a local recycling center or household hazardous waste facility.

How to Store Hot Cooking Oil?

To store hot cooking oil safely, you should:

  1. Let the oil cool down to room temperature before storing it.
  2. Use an airtight container to prevent air from getting in and spoiling the oil.
  3. Store the container in a cool, dark place to prolong the oil’s shelf life.

What to Consider When Reusing Fryer Oil

Reusing fryer oil can save you money and reduce waste, but there are some things to consider:

  • Don’t reuse oil that has been heated to the smoking point, as it can release harmful chemicals and affect the taste of your food.
  • Strain the oil before reusing it to remove any food particles or debris that can affect the quality of the oil.
  • Keep track of how many times you’ve reused the oil, as it can become rancid and spoil after a certain number of uses.


It’s important to be cautious when handling hot oil and to use containers that are specifically designed to handle hot liquids. Glass jars and plastic containers are generally not recommended for hot oil, while ceramic bowls and Pyrex containers are safe options. Remember to properly dispose of cooking grease and store hot cooking oil in a cool, dark place. By following these tips, you can safely handle hot oil and prevent accidents in the kitchen.
