If you have a taper candle on hand, you could also light that, then reach the lit candle down into the jar.
Flip the candle right-side-up as soon as the wick lights so you don’t spill any wax as it melts. Doing this on its own may be enough to light the candle, but you can also try this with any of the following techniques for even more reach.
Since you’ll be holding the lighter near the bottom, you’ll be able to reach the lighter further down toward the wick. You also won’t have to ball up your fist, so you may be able to slip your fingers further into the jar.
Turning the candle sideways can help make this easier. Be sure not to hold the match upside-down, as the flame could lick upward and burn you.
Don’t shake the paper to put it out, as you could send hot embers flying. Work fast, as the paper will probably burn quickly. Also, be sure you’re set up to put out the flame before you ever light the paper. The tighter you twist the paper, the more slowly it will burn. [6] X Research source
To put out the spaghetti, either shake the flame out or dip the end in a little water. Lighting the end of a wooden chopstick may work in a similar way.
This is easiest if the wax is slightly hardened but still soft. However, you can still try it if the wax has cooled completely—it might just take a little more elbow grease. If you’d like, you can save the excess wax to use in a wax warmer.
Try not to leave the blow dryer pointing at any one place for too long. Otherwise, the glass jar could start to get hot, making it difficult to handle. Similarly, you could place the candle on a baking sheet, then put it into an oven heated to 175 °F (79 °C) for 5 minutes or so. Be sure to use oven mitts when you remove it from the oven!
Leave the candle burning for about 2-3 hours, or until melted wax covers the entire top of the candle to about 1⁄4 in (0. 64 cm). However, check the candle periodically. You may need to carefully pour off any excess wax as it melts to avoid suffocating the flame. You can also wrap aluminum foil around the mouth of the candle. Just be sure to leave a hole in the top for air flow.
Trimming the wick will help prevent soot stains on the sides of your candle jar, as well. [12] X Research source Wait for the candle to cool completely before you trim the wick. [13] X Research source
In addition, if wind is blowing the flame, you’re more likely to get scorch marks on the jar. [15] X Research source
Tunnels can form at any point during the candle’s lifespan, so try to let it burn long enough every time you light it. If you want a candle you can light for short periods, choose a jar candle with multiple wicks. This will help it burn more easily. Taper candles may be a good option for you, as well. [17] X Research source However, don’t burn the candle for more than 4-6 hours. If the candle overheats, the glass could break or shatter, and it could turn into a fire hazard. [18] X Research source
When you blow out a candle, it creates a lot of smoke, and the ash from the wick can spread through the wax. That can ruin a beautiful candle.
Be careful—let the wick cool a little after you extinguish it, and don’t touch the wax, as it will be very hot.
