Your candle jars can be used again!!! When you have 1/2" or less of wax in the jar, place it on a baking sheet in a 200 degree oven for approximately 30 minutes, or until the wax is liquified (jar will be HOT). Pour it into a disposable container that is heat safe. If the wicks still cling to the bottom, take a spoon and pull them out. Wipe out remaining wax with a paper towel. You can wipe the inside of the jar with wax remover, though it isn't necessary. Place on the top rack of the dishwasher and run them through with your other dishes. They can hold all kinds of things!
