How Long Do Mason Jar Candles Last?

Mason jar candles can be an affordable, eco-friendly, and attractive option when it comes to home decor. But if you’re not following these few important tips, they can also be a waste of money! So read on for helpful hints and info on how long your candles will last.

Depending on the ventilation in your house or business, a candle can burn for up to 80 hours, and this is because only soy wax and cotton wicks are used, which are also braided and lead-free.

Scented mason jar candles are a fantastic way to banish unwanted odors from your home for hours, but misusing them could mean you’re wasting your hard-earned cash.

To get the most out of your scented mason jar candles, follow these tips:

  1. Weigh your candle containers properly. You want to keep the container light so that it doesn’t weigh down the candle, which can cause it to burn poorly. A pound of wax is more than enough to fill a standard-sized mason jar, but if you use a large container, you may need to use two or three containers filled with varying wax weights.
  2. Do not burn your candle from the bottom of the jar. The wick must be exposed to air to be consumed and replaced correctly. If you fail to do this, it will result in a poor-burning candle with a short life.
  3. Avoid burning mason jar candles in direct sunlight, near heating vents, or any other sources of heat that could cause the melting of your wax.
  4. Avoid burning your candle down to the very bottom of the jar. This will increase the amount of wax residue on the sides of your jar and, in turn, reduce its life substantially. Instead, keep a 1/2-inch to 1-inch space at the bottom of your jar free at all times. This allows you to replace the wick easily when it has been completely combusted.
  5. Also, be sure to trim your wicks every time they begin to bend or curl, as this indicates that it is time for a new one.
  6. Never leave a burning mason jar candle unattended.
  7. Try to burn your candles for about 5 hours at a time. Longer does not necessarily mean better and could cause a decrease in the overall life of your candle if it is left burning or melted for too long at once.
  8. Clean your candle holders and lids frequently. This will prevent the buildup of residue on them and ensure they are always free of any buildup.
  9. Do not use food-grade paraffin wax in your mason jar candles. Wax is highly flammable, so if you were careless with this product and created a fire, you could easily cause a massive disaster in your home!
  10. If you use dyes in your candles, make sure to use them sparingly! A little bit goes a long way with these products. You don’t want to end up with an oddly colored candle that will stick out in your home.
  11. Keep your wicks trimmed to about 1/4 inch long. If you find that your candle isn’t burning properly, this could cause it!
  12. Be sure to know where and how you will store your candles when they aren’t in use before purchasing them. If they are exposed to extreme temperatures, keep them on a stable surface and ensure they are protected from direct sunlight or other heat sources, as the wax could burn unevenly. The glass could crack or shatter due to temperature changes.
  13. Make sure that you keep your mason jar candles away from flammable materials and out of reach from children and pets.

Do candles expire if unopened?

No. To dispel any concerns you might have, candles do not have a shelf life like perishable foods. However, improper storage might cause them to lose flavor and aroma. Fragrant oils are combined with carrier wax to create candles. In most cases, the fragrance oil will evaporate first.


Your mason jar candles should last for about 30 hours before they begin to burn poorly. An easy way to keep track of when it’s time to change out the wick is to mark an ‘X’ on the bottom of each candle when you light it for the first time. This way, you can check on your candle every couple of hours and ensure that the top wax layer hasn’t been completely combusted yet!

If you’re looking for a way to add light and ambiance to your home, then mason jar candles could be a perfect choice. Follow these tips, and you can be sure you will get the most out of your candles!
