Make basic jar or container-based candles.
You will need:
several empty jars or containers
a double boiler
candle wicks (recommended: pre-waxed and wired wicks with wicks clips)
crayon pieces for coloring the wax
optional: candle fragrance
Once you've chosen your candle containers – jars, glasses, tea cups, mugs, etc. – it's time to prep them.
Make sure the containers are clean and completely dry. Then, place them on a sheet of wax paper. This will ensure that any wax spills will be easy to clean up.
Finish by inserting a candle wick in the center of each container. If you are using wicks with wick clips (little metal disks on the end), the wicks should stand up straight without any assistance. If you are using wicks without clips, you can hold the wick in position by tying the top of the wick to a pencil or straw, and balancing the pencil across the top of the container.
Assemble a Double Boiler
For safety reasons wax should always be heated in a double boiler.
If you don't own a double boiler, you can create one by placing an empty can, pan or glass container inside of one of your pans. Just make sure its not something real special that you decide to use. It will be covered with wax by the time you are done.
Cut the wax into small pieces, and place it in the double boiler. Then, heat over medium heat until the wax is melted completely.
Decide what color you want your candles to be; then, add bits of crayons in your chosen color to the wax, and heat until melted. Adjust to whatever color you would like.
Now is the time to add fragrance to the wax if want it to smell good. Turn off heat.
Never leave the stove unattended while heating wax.
Use oven mitts or pot holders to remove the wax from the stove. Then, carefully pour the wax into the the first container until it reaches the top of the container (or the desired height). Repeat with any remaining containers.
Allow the wax to cool undisturbed for several hours or until completely hardened.
Sometimes you will find a depressed area around the wick of the candle. This is a common occurrence and an easy problem to fix. Just melt some more wax, pour it into the depressed area. Once the new wax has hardened, simply trim the wick down to size; and your candle is ready to use.
Some notes, Never pour wax down a drain.
Allow any leftover, melted wax to cool; then, store the dried pieces for later use.
Clean up any wax you can find, as it can ignite if it gets hot enough. Remember to use all safety precautions. Enjoy
