If you are stashing candles, get some gel candle wax. Stick a wick inside a thick glass jar (use a hot glue gun to stick the metal wick tab to the bottom of the jar), melt the gel and pour inside the container. Wrap the wick around a pencil and lay across the rim of the jar to keep the wick straight. An oz. of this gel wax will burn for around 15 hours. So for 10 oz. of gel you will have about 150 hours of burn time.
