The duration of sterilization depends on the size of the jars and whether they are filled with food or not. Smaller jars, such as pint-sized ones, typically require 10 to 15 minutes of boiling, while larger jars, such as quart-sized ones, may need 20 to 25 minutes. If the jars are filled with food, the sterilization time should be increased by 5 to 10 minutes. Once the sterilization process is complete, the jars should be carefully removed from the boiling water using a jar lifter and placed on a clean surface to cool.
can you boil canning jars too long?

will a glass jar break in boiling water?
A glass jar can break when subjected to extreme temperature changes, and boiling water presents one such situation. The sudden and significant increase in temperature can cause the glass to expand rapidly, creating internal stresses that exceed the material’s strength. This can lead to the formation of cracks and, ultimately, the shattering of the jar.
can you put boiling water in glass?
Glass is a delicate material that can easily crack or break when exposed to sudden changes in temperature. Boiling water is extremely hot, reaching temperatures of over 212 degrees Fahrenheit (100 degrees Celsius). Pouring boiling water into a glass container can cause the glass to expand rapidly, which can lead to cracking or shattering. This is because the sudden increase in temperature causes the molecules in the glass to vibrate more quickly, which in turn causes the glass to expand. If the glass is not able to expand quickly enough, it can crack or break.
To avoid this, it is important to never pour boiling water directly into a glass container. Instead, allow the water to cool slightly before pouring it into the glass. You can also place a spoon or other metal object in the glass before pouring the boiling water. This will help to distribute the heat more evenly and prevent the glass from cracking.
will a jar explode in boiling water?
A jar placed in boiling water can explode. The sudden temperature change causes the air inside the jar to expand rapidly, creating pressure that the jar may not be able to withstand. As a result, the jar can shatter, sending shards of glass flying. To prevent this, never place a sealed jar in boiling water. If you need to heat something in a jar, place it in a pot of cold water and bring the water to a boil slowly. This will allow the air inside the jar to escape gradually, preventing the jar from exploding. Additionally, make sure to use a jar that is specifically designed for canning or boiling. These jars are made of thicker glass and are less likely to break under pressure.
how do you seal mason jars with boiling water?
Gather your supplies: clean mason jars, lids, and rings, a large pot, a jar lifter, and a towel. Fill the pot with enough water to cover the jars by at least 1 inch. Bring the water to a boil. Carefully place the jars in the boiling water using the jar lifter. Boil the jars for 10 minutes. Remove the jars from the boiling water using the jar lifter and place them on the towel to cool. While the jars are cooling, prepare your lids and rings. Place the lids in a small bowl of hot water to soften the sealing compound. Place the rings on the jars. When the jars are cool enough to handle, carefully remove the lids from the hot water and place them on the jars. Screw the rings onto the jars until they are fingertip tight. Let the jars cool completely before storing them.

why do you put jars upside down when canning?
There are several reasons why you may want to turn jars upside down when canning. First, it helps to create a vacuum seal. As the jar cools, the air inside contracts and the lid is sucked down, creating a seal that helps to preserve the food. Second, it helps to prevent the food from coming into contact with the air, which can cause spoilage. Third, it helps to distribute the heat evenly throughout the jar, ensuring that the food is cooked evenly. Fourth, it helps to prevent the jars from breaking during the canning process. Fifth, it helps to keep the food from floating to the top of the jar, which can make it difficult to remove later. Finally, it helps to ensure that the food is properly preserved and safe to eat.
