Mason jars have become increasingly popular in recent years, and it’s not uncommon to see people using them as coffee cups. But can hot coffee really go in a mason jar? The answer is not a simple yes or no. In this article, we’ll delve into the world of mason jars and hot coffee, exploring the pros and cons of using a mason jar as a coffee cup.
The History of Mason Jars
Before we dive into the world of hot coffee and mason jars, let’s take a brief look at the history of mason jars. Mason jars have been around since the mid-19th century, when they were first patented by John Landis Mason in 1858. Mason’s design featured a screw-on lid and a rubber ring that created a vacuum seal, making it ideal for canning and preserving food.
Over the years, mason jars have evolved, and today they come in a variety of shapes, sizes, and materials. However, the basic design has remained the same, with a focus on creating a tight seal to preserve food and drinks.
The Science of Thermal Shock
So, can hot coffee go in a mason jar? The answer lies in the science of thermal shock. Thermal shock occurs when a material is subjected to sudden and extreme temperature changes. In the case of a mason jar, thermal shock can occur when hot coffee is poured into a cold jar.
Most mason jars are made of glass, which is a poor conductor of heat. When hot coffee is poured into a cold glass jar, the glass can expand rapidly, causing it to become brittle and prone to breakage. This is known as thermal shock.
However, not all mason jars are created equal. Some jars are made of tempered glass, which is designed to withstand extreme temperature changes. Tempered glass is made by heating the glass to a high temperature and then rapidly cooling it. This process makes the glass more resistant to thermal shock.
Tempered Glass vs. Regular Glass
So, what’s the difference between tempered glass and regular glass? Tempered glass is designed to be stronger and more resistant to thermal shock than regular glass. When tempered glass is subjected to thermal shock, it is less likely to break or shatter.
Regular glass, on the other hand, is more prone to breakage when subjected to thermal shock. This is because regular glass is not designed to withstand extreme temperature changes.
The Pros and Cons of Using a Mason Jar for Hot Coffee
Now that we’ve explored the science of thermal shock, let’s take a look at the pros and cons of using a mason jar for hot coffee.
Pros:

Cons:
- Thermal Shock: As we discussed earlier, thermal shock can occur when hot coffee is poured into a cold mason jar. This can cause the glass to break or shatter.
- Heat Retention: Mason jars are not designed to retain heat well. This means that your coffee may not stay hot for as long as you’d like.
- Lid and Seal: Mason jars have a screw-on lid and a rubber ring that creates a vacuum seal. However, this lid and seal can be prone to leakage, especially when used with hot liquids.
