One of our craft projects is making real beeswax tapers, hand dipped. They are very practical and simple to make. I will not only explain what supplies you need and how to dip them but the benefits of beeswax over paraffin based candles.
Lets start at the beginning. Beeswax. I usually buy real beeswax from a candle making supplier, or you can find a local bee keeper or even buy it on E-Bay or Amazon. I use unfiltered beeswax. It's a little more primitive and the candles come out with interesting characteristics. No two are the same. If you plan to burn any candles in your home, you first need to get a sturdy candle holder and put it in a safe place with something under the candle holder to catch melted wax. Also be sure no papers are anywhere nearby. We had an old cat who walked on the table where the candle was burning. He walked OVER the lit candle if it was short enough and almost set himself on fire repeatedly. Also children can be a factor in safety. I have a son who LOVES fire. I taught him how to start a fire with just a flint and steel and some tinder . I always worry about him burning the house down.
Supplies. You will need to get 2 equal size metal cans or buckets. You can use large / tall olive oil cans. The taller the better. You can also find good containers at a kitchen supply company or simply by going to yard sales. You will also need a thick metal pail to melt the wax in on the stove top. The olive oil tin can be used but generally they are very thin and not very sturdy. Keep in mind that the bigger/wider the pail, the more wax you will need to melt to get the melted wax high enough to make 7" to 8" tall candles. So keep it narrow but tall. Where the olive oil tins come in handy is holding cool water . I'll explain shortly.
Now for the hard part. Wicks. This is basically trial and error and experimentation. The thicker the wick the hotter and brighter the candle will burn, but it won't last as long. So you need to find a compromise. There are many types of wicks too. Some are pure cotton, some have a metal wire in them to keep them standing up straight. Many different thicknesses add to the confusion. Your best bet is to talk to the candle making supplier to start and specify you are using real beeswax, as some wicks are better suited to beeswax than paraffin. I usually get several thicknesses of wicks to experiment with. It's a never ending experiment. Very thin wicks don't burn brightly and sometimes the melted wax at the top extinguishes the flame. I go with a thicker wick normally. Beeswax candles usually burn much longer than commercial paraffin based candles and beeswax is not only a renewable material but it burns cleaner than paraffin.
Paraffin is a petro-chemical and gives off fumes similar to diesel exhaust. Beeswax burns cleaner and gives off no toxic fumes and has the benefit of actually cleaning the air through the use of negitive ions, which attract pollutants. They also leave the room smelling of honey and lend a beautiful atmosphere to any meal or occation.
To start dipping I always put down tin foil over the stove and the floor right by the stove. I am very good at making a big mess and my wife is very good at reminding me of it. The wax should be cut into small pieces and put into the metal pail. Turn on the stove top and keep it on a low setting. Any wax will catch fire if it gets too hot, so use a lot of caution and never walk away from the stove when the flame is lit. You will need some heavy duty oven mitts or gloves to handle the hot pail . I get the wax melting slowly while I fill the olive oil tin with cold water and put it on the tin foil on the counter top , close to the wax.
I get my wicks ready. I normally make 1 pair at a time. Using one long wick, I dip both ends at once, giving me 2 candles at once. First I attach a metal washer to the end of each side of the wick. This will give it enough weight to sink to the bottom of the wax container. Just put the end of the wick through the hole in the washer and tie a simple knot. You will need to gauge how long to make the wicks. Use as little as you can get away with to be frugal. Any wick length between the 2 candles needs to be kept to a minimum so you don't waste wick material. When you are done you can either cut the 2 candles apart or just hang them up , like I do in the above photo.
O.K. , the wax has melted and you have the 2 washers tied to the ends of your wick. The cold water is ready and the tin foil is down to make a fire resistant surface. You also have your gloves or mitts close at hand, but not close to the fire. You are all set. Start by holding the wick in the center being sure the ends are as even as you can make them. Put 2 fingers under the center of the wick while you hold it. This will seperate the 2 candles and keep them from sticking together.
Dip them slowly into the wax. Let the washers hit the bottom then slowly pull them out and dip them in the cold water to harden that layer. Repeat this about 4-5 times then it should be heavy enough to cut the washers off. As soon as you cut them off you should scrape out the wax before it hardens fully to make the next set of candles easier. Getting hardened wax out of the washer openings is difficult. After that you can continue to dip then cool the candles until you reach the thickness you want. I generally make them about 3/4" wide at the base. This should allow them to fit most candle holders. You can always trim the base to make it fit and melt the base to make it stick into the holder more securley. After the candle is the right size, hand it up to dry, or if it's cooled down enough, lie it down on foil or waxed paper. Hanging is better as it has nothing to deform the shape or has anything to stick to.
Tempreture of the wax. As a rule of thumb, the hotter the wax, the more times you will need to dip it to get your desired thickness. Each layer will be thinner because the wax is thinner. I usually go for a slightly cooler wax. This is safer and lets me dip the candles fewer times. When you make candles, it's more econamical to make as many as you can at once. You have to heat the wax, which can take an hour or more, depending on how much wax you need to melt. Then you need to constantly add more wax, in small pieces ( which melts faster, using less fuel) so have wax in small pieces ready. Be very careful not to drop the pieces in as the spashing wax is a fire hazzard and a burn hazzard. When my kids help, which they love to do, I am always right there to supervise.
Options. There are various types of beeswax you can buy. Different scents and colors. It depends on the plant or flower the bees collected the pollen from and thereby made the wax from to seal the comb with. The comb wax is used by the bees to seal in indevidual chamber of the honey comb, where the bee larve are housed until mature. When they are ready you can harvest the "cap wax" that forms the seal and use it for candles. You can also buy scented oils to add to the wax. But I found that since I need to always add more wax, I either need to stick to one scent or use none at all. If you mix the oil scents it will smell kind of funky. If you are planning to sell the candles you need to strive for consistency. Also some people are allergic to the scents or just don't like them, so I don't use them in my candles.
Anoter option is to pour the wax into a mold. I have tried many types of molds, and I find the ones made of silicone are the easiest to work with. They are easy to use and easy to clean as well. Molds made from aluminum or steel need a wax release spray or you will never get the candle out. They usually have a small wick hole in the bottom if metal. Either way you will need special wicks. They come in bags and have a round metal base into which the wick is pre-inserted by the manufacturer. Most of them have a thin wire in the wick to help it stand up straight.
If using the silicone molds, you simply put the wick with the base in the bottom. Try to center it as best you can. Slowly pour the melted wax into the mold being very careful not to splash any on yourself. If you pour it too fast it will be hard to keep the wick centered. The lenghth of the wick should be taller than the mold so you can stabilize it. I put the still hot candle in the mold in the freezer for a little while so it cools faster. When it's cool you can flex the mold to release the candle.
Molds can be found in all kinds of shapes and sizes and textures. We use one that has a pebbely texture to it and looks like it's made of stone. The trick to getting a good looking candle is to pour the wax to the top of the mold and when it settles as it cools you might need to top it off. Also let it cool long enough to harden a bit before you try to remove it from the mold. If you plan on making a number of candles at once, you may want to buy several molds to keep the process moving along.
