The answer to this question is no, you cannot put a mason jar on a hot plate. This is because mason jars are made of soft glass and are not heat-resistant. When heated, they can easily crack, shatter or explode, leading to injury or damage to your equipment.
Can You Put a Mason Jar on a Hot Plate?
To avoid accidents when using hot plates, it is important to understand the type of glassware that can be used safely, and the precautions that should be taken when heating them.
Types of Glassware Suitable for Hot Plate Use
Heat-resistant borosilicate glassware is the recommended type of glassware for use on hot plates. This type of glassware is specially designed to withstand high temperatures and sudden changes in temperature without cracking or breaking. It is also highly resistant to thermal shock and chemical corrosion.
Some examples of heat-resistant borosilicate glassware include beakers, test tubes, flasks, graduated cylinders, and watch glasses. These types of glassware are commonly used in laboratories, science classes, and research facilities.
Precautions When Using Glassware on Hot Plates
When using glassware on a hot plate, there are some important precautions that you should take to prevent accidents and ensure safety.
Check for Cracks
Before using any glassware on a hot plate, it is important to check for cracks, chips, or other damage. Even the smallest crack can weaken the glassware and increase the risk of breakage during heating. If you notice any damage, replace the glassware before using it on a hot plate.
Do Not Use Thick-Walled Glassware
Thick-walled glassware, plastic containers, soft-glass bottles or jars are not suitable for use on hot plates. This is because these types of glassware are not designed to withstand high temperatures and can easily crack or shatter when heated. They can also trap heat inside, causing the glassware to break or explode.
Choose a Suitable Hot Plate
When using a hot plate, it is important to choose a suitable one for your glassware. The hot plate surface should be larger than the vessel being heated to ensure even heating and prevent spills. It is also important to use a hot plate with temperature controls to avoid overheating the glassware.
Conclusion
In conclusion, mason jars are not suitable for use on hot plates because they are made of soft glass and are not heat-resistant.
It is important to use heat-resistant borosilicate glassware on hot plates and take precautions such as checking for cracks, not using thick-walled glassware or plastic containers, and choosing a suitable hot plate for your glassware.
By following these precautions, you can ensure safety when using hot plates in the laboratory or at home.
