Empty Candle Jars: Clever Ways to Reuse the Glass at Home
A good candle jar is a genuinely useful little vessel, and it feels wasteful to drop it in the recycling the moment the wax runs out. With a quick clean, that glass can have a long second life as a holder, a planter, or a dozen other small things around the house. Reusing it keeps it out of the waste stream entirely, which is the cleanest possible outcome. Here is how to get the jar ready and the best ways to put it back to work. We make 100% beeswax candles, and the full collection is here as you read.
Getting the last wax out
Before a jar can be reused, it needs to be clean, and the easiest tool for that is temperature. Pop the jar in the freezer for an hour or so, and the leftover wax shrinks and hardens enough to lift out in a piece or two with a butter knife. If you would rather use warmth, set the jar in a bowl of hot water until the wax softens and floats free, then wipe it out. Lift out the metal wick tab, wash the glass with warm soapy water, and peel off the label. A little adhesive remover or a soak handles stubborn label glue.
Holders and organizers
The most obvious second life is as a holder, and candle jars are perfect for it. On a desk, one corrals pens, pencils, and scissors. In a bathroom, it keeps cotton rounds, swabs, or makeup brushes tidy. On a vanity it holds jewelry or hair ties, and in a kitchen drawer it can keep small utensils together. Because the glass looks intentional rather than like packaging, these little organizers look good out on a surface instead of hidden away.
Plants and the kitchen
A clean jar makes a charming little planter for a succulent or a herb cutting, and it is a lovely way to start propagating clippings in water on a windowsill. In the kitchen, jars are useful for storing spices, dried goods, or homemade things like overnight oats, and a matching set of reused jars looks surprisingly smart in a pantry. Just make sure the jar is fully clean and food safe if you are storing anything edible in it.
A second drinking glass
Many candle jars, once the label is off and the glass is clean, make a perfectly good drinking glass or a vessel for a cold drink. A straight sided jar in particular works well for this, and it is a satisfying way to give a piece of packaging a genuinely everyday use. If you are unsure whether a particular jar is meant for it, simply use it for cold drinks rather than hot.
A note on the lid
Do not overlook the lid if your candle came with one. A jar with its lid becomes a sealed container, which is far more useful for storing spices, small craft supplies, beads, buttons, or anything you want to keep dust free. The lid also turns a jar into a tidy little travel container. Keeping the lid with the jar doubles what you can do with it.
Why reuse beats recycling
Recycling glass is good, but reusing it is better still. Recycling takes energy to melt the glass down and remake it, while reusing a jar as it is keeps it in service with no further cost at all. Every jar you repurpose is one that does not need to be processed or replaced, which is the most genuinely sustainable thing you can do with it. A clean candle jar is too useful to melt down when it could simply keep being a jar.

The quality of the jar is part of what makes it worth keeping:

Turn it into a gift jar
A clean candle jar makes a charming little container for a homemade gift. Fill it with bath salts, cookies or granola, sweets, a small bundle of tea, or a tiny succulent, add a ribbon, and you have wrapped a present in something the recipient can then reuse themselves. It is a thoughtful, low waste way to give something small, and the glass looks far nicer than a plastic tub or a bag. One jar becomes the wrapping and a keepsake in one, which is a fitting end for a vessel that already gave you a good candle.
Common questions
How do you clean out an empty candle jar?
Freeze the jar so the wax hardens and pops out, or warm it in hot water so the wax softens and lifts free. Then remove the metal wick tab, wash the glass with warm soapy water, and peel off the label. Once it is clean and dry it is ready to reuse. The collection comes in jars worth keeping.
What can I do with empty candle jars?
Plenty. Use them as holders for pens, brushes, or jewelry, as planters or propagation vases, for spice and dry goods storage, or as drinking glasses once cleaned. With the lid kept, they make handy sealed containers for small items too.
Are candle jars worth keeping?
Usually, yes. A good glass jar is a sturdy, attractive little vessel that is genuinely useful around the house, and reusing it keeps it out of the waste stream entirely. Reusing is even better for the environment than recycling, since it skips the energy of melting the glass down.
The bottom line
An empty candle jar is too useful to toss. Clean out the wax, peel the label, and give the glass a second life as a holder, a planter, or a container, which keeps it in use and out of the bin for good.
