Blue mason jars are food safe as long as they are properly sealed. The sealing process is what makes them airtight and prevents bacteria from growing. If you’re using a jar that has been previously used, make sure to clean it thoroughly before using it again.
It’s also important to check the seals on your jars before each use to ensure that they are still intact.
Yes, blue mason jars are food safe. They’re made of glass, which is a non-porous material, so they won’t absorb flavors or odors from food. Plus, they’re dishwasher-safe, so you can easily clean them after use.
Are Old Mason Jars Safe to Use
When it comes to canning, many people swear by Mason jars. And while these jars are definitely safe to use for canning purposes, you may be wondering if they’re also safe to use for other things – like storing food in the fridge or freezer.
The answer is yes!
Old Mason jars are perfectly safe to use for storing food. In fact, they’re actually ideal for this purpose because they’re made of thick glass and have a tight-fitting lid that helps keep air out and food fresh.
So if you’ve got some old Mason jars lying around, don’t hesitate to put them to good use!
Just make sure to give them a good wash first.
When Did Ball Stop Making Zinc Lids
In the early 1900s, most food was canned in Mason jars with zinc lids. The lids had a small hole in the center that was covered with a piece of cloth or paper and held in place with a rubber band. This allowed the hot air to escape from the canning process and ensured that the food remained fresh.
Over time, canning methods improved and Ball stopped making zinc lids. Now, most food is canned with screw-top lids made of plastic or metal. The screw-top lid creates an airtight seal that doesn’t require a cloth or rubber band.
This type of lid is also easier to open and close than the zinc lid.
Canning Jars
If you’re interested in canning your own food at home, you’ll need to invest in a good set of canning jars. Canning jars are specially designed to withstand the high temperatures involved in canning. They come in a variety of sizes, so you can choose the right size for your needs.
Canning jars have two parts: the jar itself and the lid. The jar is made of heat-resistant glass, while the lid is made of metal with a rubber seal. The lid must be tightly sealed on the jar in order for the contents to be properly preserved.
When choosing canning jars, look for ones that are free of chips or cracks. Canning jars should also be smooth on the inside so that food doesn’t get stuck to them. It’s also a good idea to buy extra lids just in case one gets damaged or lost.
Canning jars are an essential piece of equipment for any home cook who wants to preserve food at its best. With proper care, they will last for many years and provide you with delicious homegrown meals all year long!
Mason Jar Lid Change
One of the great things about Mason jars is that they are so versatile. You can use them for canning, storage, or even as drinking glasses. But one thing that can be a bit tricky is changing out the lids.
Depending on what you’re using the jar for, you may need to change out the lid to get a tight seal. Here’s a quick guide to help you change those Mason jar lids like a pro!
Start by removing the old lid from the jar.
If it’s stuck on, you may need to use a butter knife or other tool to pry it off. Once the old lid is off, clean both the inside of the jar rim and the underside of the lid with warm soapy water. Rinse well and let air dry completely.
Now it’s time to select your new lid. If you’re using the jar for canning, make sure to choose a new canning lid that has never been used before. For other uses, any type of screw-on lid will do – just make sure it fits snugly on top of the jar.
To attach your new lid, simply screw it onto the jar until it’s tight. That’s all there is to it!
Are off Brand Canning Lids Safe
If you’re like most people, you probably have a few off-brand canning lids in your pantry. But are they safe to use?
The short answer is yes, off-brand canning lids are perfectly safe to use.
In fact, they’re often just as good as the more expensive name-brand lids. The only difference is that off-brand lids may not be compatible with all canning jars (such as those made by Ball or Kerr). So if you’re using an off-brand lid, make sure to check the manufacturer’s instructions to see if it will work with your particular type of jar.
Other than that, there’s no need to worry about using off-brand canning lids. They’ll seal your jars just as well as any other kind of lid and will help keep your food fresh for months (or even years) to come!

Are Blue Canning Jars Safe to Use?
Yes, blue canning jars are safe to use. While the color of the glass may cause some light to be scattered, this does not affect the safety of the food inside. The FDA has approved blue glass for food contact, and it is also commonly used in baby bottles and medical devices.
Why are Some Mason Jars Blue?
One of the most common questions we get here at Ball is “Why are some mason jars blue?” It’s a good question, and one with a relatively simple answer.
First, a little bit of history.
The Ball brothers began their canning journey in 1884 when they started producing glass fruit jars. They quickly became a success, and by 1886 they were operating eight factories across the United States. These early jars were made of clear glass, which was perfect for showing off the vibrant colors of fruits and vegetables inside.
However, there was one problem with clear glass jars: they were very susceptible to breakage. In 1906, the company began experimenting with different colors of glass, eventually settling on blue as the best option for protecting against breakage while still allowing light to pass through (which is necessary for preserving food). Blue also had the added benefit of looking quite pretty on shelves filled with colorful preserves!
Nowadays, you can find Ball mason jars in a variety of colors beyond blue – including green, purple, pink, and even black – but blue remains the most popular choice. So next time you see a jar of homemade jam or pickles sporting a beautiful blue hue, you’ll know it’s not just for looks – it’s actually serving an important function in helping to keep your food fresh.
Are Blue Canning Jars Better?
There are a few schools of thought on this topic. Some say that blue canning jars are better because they block out more light, which in turn helps preserve the food inside for a longer period of time. Others argue that any color canning jar will work just fine, as long as it’s made of high quality glass.
Ultimately, the decision of whether or not to use blue canning jars is up to the individual home cook.
When Did They Stop Making Blue Mason Jars?
There are a few different stories about when blue mason jars were no longer produced. One story says that the company that made them, Ball Mason Jars, stopped production in 1937. Another story says that the last blue mason jar was made in 1945.
The truth is, we don’t know for sure when they stopped making blue mason jars. What we do know is that they are now considered to be collector’s items and can sell for a lot of money. If you have a blue mason jar, you may want to hold on to it!
