From birthday bashes to romantic dinners, the sparkling shimmer of soft candlelight instantly makes any moment more magical and special. But once you snuff out the candles and the smoke clears, what do you do with those puddles of melted wax? You might think of banishing these useless blobs to the trash bin or the back of your cluttered closet, but think again. Did you know that you can make new candles from your old ones in just a few simple steps? The process is simple, so no need for kits or complicated instruction pamphlets found in other candle-making methods. The technique you'll learn in this article is easy, inexpensive and environmentally-friendly

Making new candles from old ones is a great money-saver because you can use materials that you already have around the house, such as old candles and old glassware or dishes, rather than buying all new materials. You can also help make the Earth a little greener by recycling old candle wax and keeping it out of the trash.

Before you begin recycling your old candles, you will need to make sure that you have a few important materials on hand, including a sufficient amount of old wax or candle pieces and a melting device to melt the wax. A double boiler or two old sauce pans that can be fashioned into a double boiler are the melting devices preferred by many candle crafters. Additionally, you will need pre-waxed wicks, which are available at most craft and hobby stores [sources: Peterson, DIY Network, Candle Help].

Making New Candles from Your Old Candles

In order to make a new candle, you'll need to melt old wax pieces together. For best results, make sure that your old wax pieces are very similar in scent or color before you begin. Mixing together too many different scents or colors of wax may result in an unpleasant scent or an unattractive color [source: Peterson]. You'll also want to make sure you break up the wax pieces into smaller chunks using an old knife or a hammer and chisel. Smaller pieces will make removing the old wicks and melting the wax easier [source: DIY Network]. If you cannot remove the old wicks, filter the wax through cheesecloth during pouring to catch wicks and any other debris [source: DIY Network].

Once you've collected your old candle pieces, select the molds you want to use. Shot glasses, sake cups, coffee mugs and other glass or ceramic objects make good candle molds [source: DIY Network]. Prep the mold with a thin layer of cooking spray or wax release spray to make it easier to remove the candle once it's cool [source: Candle Help]. Then center the pre-waxed wick in the bottom of the mold. You can also set the wick after you pour the hot wax, if you prefer.

Now that your mold is ready, set up your melting device. Heat a double boiler on your stove or create your own by setting an old sauce pan into a slightly larger one filled half-way with water. When the double boiler is hot, place the wax chunks into the top part to begin the melting process. When the wax has melted, pour the liquid wax into your mold and let it cool. Then trim the wick, light it and watch your new candle glow!
