21 Brilliant Ways To Reuse Glass Jars

All throughout the year, glass jars are in season.

Pickle jars, mustard jars, jam jars, peanut butter jars, Mason jars…

Tall ones, short ones, blue ones, clear ones. Glass jars can be found in all sizes and colors. They are omnipresent, in abundance and infinitely useful.

Glass jars can surely be recycled when you are through with their contents, but do they have an even higher purpose?

We believe so, and have 21 ways to prove it.

Creating a zero-waste home

In the spirit of living sustainably and creating as little waste as possible, chances are great that you are already limiting the amount of plastic in your home. That’s wonderful news – and a terrific place to start on your quest to embrace all the brilliant uses for glass jars!

The choice to adopt a zero-waste mindset, allows you to (re)think of materials in a new light.

And with a sustainable future in mind, the concept of zero-waste is about creating a circular economy that keeps good materials in motion – in essence, removing the idea of trash.

Glass is an exceptional material that can be reused for as long as it does not break, far better than plastic containers in any event!

Why glass is better than plastic

Glass is superior because it is:

  • non-porous, meaning that it won’t transfer food smells
  • keeps foods safe (without leaching any harmful material into them)
  • reduces landfill waste
  • saves money
  • easy to clean
  • plus, it looks better than plastic

Please remember, never use non-canning jars for canning purposes!

Canning jars are built to withstand both heat and pressure, other random jars can crack, even explode, when brought to high heat.

If you have vintage jars that are just too beautiful to throw away, use them as vases or decorative containers. Keep items in use that make you happy – recycle or re-gift the rest!

That being said, what do you do with all of those leftover jars that have no place to go?

21 Ways to Reuse Glass Jars

Once you put your mind to it, you will start seeing potential uses for your glass jars everywhere! On Pinterest, on Instagram, on every other social media channel, and beyond.

In our home, glass jars get reused on a frequent basis, since we do a lot of canning and preserving, to the tune of 150-250 jars a year.

Jam out, chutney in, some version of preserves gone on to another foodstuff, such as dried mushrooms.

We also use them for lunches on the go, as simple vases, or an impromptu drinking vessel for herbal teas. Anything goes.

Surely we can be more creative than that?!

Read on to discover more ideas on how to reuse your glass jars, to inspire you further.

However, if you are simply looking to make an occasional jar of salsa, or a smaller batch of sauerkraut, any clean old jar will do. To keep the ferment happily under the water, just add a smaller glass cup as a weight on top (one that fits inside the jar opening).

As we forage and dry our wild findings throughout spring, summer and fall, we know that storing them properly is essential.

They must remain dry throughout the winter months, to be of use in herbal teas when they are needed. One way to store them, is in breathable, natural fiber bags, the more elegant option however is glass jars with labels.

If you have open shelving, a full shelf of herbal home remedies is a wonder to behold – everyone can admire your homestead and foraging skills from afar. Especially when those jars harmonize among one another too.

5. Bulk goods

Pulses, honey, coconut flour, nuts; anything goes.

Naturally, you will have to be careful when the jars are full and heavy, but the thought and act of helping the environment is definitely worth the extra effort.

If you are lucky enough to have a store with refillable options near you, take advantage of it – and don’t forget to bring along your own jars for refilling!

6. Storing lard and tallow

Decorating glass jars

If you would prefer to embellish your plain glass jars (rather than leave them “as is“), there are a few things you can do to make them your own.

For starters, give them a good wash by soaking them in hot soapy water to remove the label. Some labels wash off easily, others are a bit more stubborn.

The more resistant labels may take some scraping with the back of a knife, or with the aid of steel wool, to remove them.

You can then wrap them with twine or yarn for a rustic look.

Glass jars can be painted inside – or out! Just be mindful about what you put in them once they are painted, stay clear away from food storage.

Perhaps even more beautiful is when they are etched with your very own design!

You could also add stylish chalk labels to your Mason jars, so that you never confuse sugar for salt again!
