Essential oils are used in lotions, creams, aromatherapy and perfumes and in many more products where a pleasant smell is needed. A number of methods are used in order to extract the essential oils from plant material and flowers. Essential oil makes up only a tiny percentage of the plant or flower therefore a considerable amount of plant material is used to produce a small amount of oil. In excess of 100 pounds is generally needed to produce one ounce of essential oil. A number of plants are also much too fragile to use the cheaper methods and more time consuming and expensive methods have to be used. Essential oils are often very expensive although they are very concentrated. Most recipes only require a few drops so a tiny bottle may last for a many months or years.

Steam Distillation

Steam distillation is in use for most of the essential oil manufacture. Pressurised steam is passed through the flowers placed on mesh screens inside a still. The oils are absorbed by the steam which then is lead to a further compartment where it is cooled down. On condensing the oil floats on the top of the water and is skimmed off. The water left behind is called floral water and can be used as it contains small amounts of the oil. It is used for mists and toners. Floral water may be used by people who are hypersensitive to essential oils as it is less concentrated.

Solvent Extraction

For plants and flowers too fragile to use steam extraction, another method such as solvent extraction must be used. In this technique a solvent is passed over the flowers on mesh trays. The esential oils, together with some other soluble materials, are absorbed by the solvent which is then filtered and the resulting solution distilled to take off the solvent. The material left, called a concrete, is a waxy solid that contains the pigments, essential oils and waxes from the flowers. Some further processes are then used in order to extract the oils and waxes from the concrete. The concrete is used in perfumes and the waxes are used in lotions, creams and in candle making.

Enfleurage

For flowers or plants with only extremely low percentages of essential oils, such as jasmine, a different technique needs to be used. Flowers are placed into odourless vegetable oil and left for a few days and then the plant material is replaced. Fresh flowers are repeatedly placed in the vegetable oil until the oil is saturated with the oils from the plant material. Alcohol is then used to extract the essential oil from the vegetable oil. The alcohol is evaporated and the unadulterated essential oil is left behind. This treatment takes many days and uses a large amount of plant material and the resulting oil is very expensive.

Cold Pressing

Some oils such as citrus, in which the oil is extracted from fruit not plant material, use a procedure known as cold pressing. This entails rolling the fruit between spikes which pierce the peel and then the fruit is squeezed to extract the juices which contain the oil. The resulting juice is then centrifuged to separate and collect the essential oil.

Carbon Dioxide Extraction

In this method carbon dioxide is used to remove the essential oil. The gas is pumped into a chamber that contains the flowers or plant material. When the pressure increases the gas liquifies and absorbs the oils. The gas is then let into a further compartment where the pressure is released. The carbon dioxide vapourises which leaves behind the essential oil.

As no residues are left the oil is extremely clean and has a lovely, fresh fragrance. As the temperature used is much lower than that used for steam distillation, essential oil can be extracted from delicate plants and flowers that are ruined by steam distillation.

People everywhere are enjoying this fun hobby and learning to make thier very own handmade candles for themselves. All different kinds of candles can be made, including dipped tapers, votives, pillars and more, and there are all kinds of different colors, sizes and scents available. It's easy to do, too, so just about anybody can make their own candles.

You can make anything from a decorative centerpiece candle to scented jar candles to practical lighting candles. Mistakes are easily dealt with - just melt your candles down and try again if you don't like what comes out. Because of this, candle making is one of the most forgiving hobbies in the world.

You can choose to purchase a candle making kit for your first candles, try the craft store for some basic supplies purchased separately, or order from a specialty candle making store online. Each method has its benefits and downsides.

Kits come with all the components you need, but can be limiting since you don't get to select them. Local stores allow you to purchase your own supplies, but may not have a great selection. Online shops offer the largest range of options, but you don't get to see your purchases before you buy, so research is important.

No matter how you get them, the supplies and tools you'll need to make your first candles are relatively simple. You'll require some candle wicks and wax, a method of melting the candles (double boilers and microwaves are both popular), and a method of protecting your work surface from wax like heavy plastic or newspaper.

You'll also need molds for candles like votives and pillars, and jars for soft waxes that never become quite solid. If you want to do things the old fashioned way and use a dipped candle, make sure you have something to dip into that's deep enough, a place to hang finished candles for cooling, and something to suspend wicking from. All candle makers will also need a thermometer.

Don't do any candle making around your pets or your kids, and make sure you take safety precautions like wearing the proper clothing. This will keep you from having to deal with spilled hot wax and the burns that come from it. There are low temperature specialty waxes that aren't as dangerous, however.

Most people also like to color and add a candle fragrance with a combination of dyes and perfumes. While these are chemicals, most of them are non toxic - just don't eat them. Make sure you remember that candle dyes can stain, so handle them with care and add them to your melted wax slowly to prevent mottling.

That's really all you need when it comes to basic candle making, and the supplies can be pretty inexpensive. A few old candle stubs, some wick, and a jar can help you make your first practice candles. Once you get used to doing it, you can work with multiple colors, mix your own shades, and work in more creativity.
