We all collect jars full of half burned candles, and eventually end up with cluttered jars everywhere. Using a project I found on Pinterest I recycled the wax and made a layered candle. Using a sink, fill it with hot water and place the jars into the water. Allow the jars to “float around” for a bit until you can scoop out the wax with a spoon. Clear any debris from the wax including the old wick and melt the wax using your preferred method (double boiler, boil bags). Wick and fill the mold.
