There's something about mason jars. They're rustic, homey, and have a certain charm that just makes them irresistible. They've become synonymous with a certain type of lifestyle—one that's simple, sustainable, and eco-friendly. We're, of course, talking about the zero waste movement.
But it's not just eco-warriors like us who are big fans. You've probably seen mason jars everywhere, from Pinterest DIYs to your favorite hipster cafe.
Besides being reusable and charming, another big reason that mason jars are so popular is that they're great for storage because they're airtight. Or are they?
One of the main reasons people love mason jars is because they believe they are airtight. This makes them ideal for storing food, both in the fridge and pantry. If you're trying to eat more healthy and home-cooked meals, then mason jars are a great way to meal prep and store leftovers.
Mason jars are made of glass, which is a non-porous material. This means that the surface of the glass does not have any tiny holes or pores that liquids or gases can pass through. In theory, this should make mason jars airtight. However, in practice, it's not quite that simple.
To simply answer the question - the truth is that mason jars are not perfectly airtight. There is always going to be some amount of air leakage unless heat sealed in a proper canning process.
The good news is, however, that the amount of air leakage is usually negligible. Unless you're storing something sensitive, like homemade preserves or pickles that need to be kept in an oxygen-free environment, a little bit of air leakage isn't going to make a difference.
Another reason people love mason jars is that they're made of glass, which is a sustainable material. Glass can be recycled over and over again without losing its quality, so using mason jars helps reduce your environmental footprint. Plus, glass is non-toxic and doesn't leach chemicals into your food like some plastics can.
Mason jars have endless uses beyond just storing food—you can use them to make homemade candles, organize your desk supplies, or even start a small herb garden. The possibilities are endless!
So next time you see a mason jar, don't hesitate to pick it up—you'll be glad you did!
Are mason jars airtight? Technically, no. But as long as there is a good seal on your jar lids, they will still be great for food storage - and probably healthier than plastic containers.
So there you have it—the truth about mason jars. While they're not perfectly airtight, they're close enough that you don't need to worry about your food going bad if you store it in a mason jar with a tight-fitting lid. So go ahead and enjoy your favorite foods in mason jars without worry!
