Manufacturing Process and Uses of Candles

The manufacturing process of a candle involves three steps; first, preparing the wick, second, preparing the wax base and the last step is extrusion or continuous moulding of the finished product. To give you an understanding of the process, this article is going to give information on each step and the practical uses of candles.

Preparing the Wick

Generally, the wick is made of linen or cotton and they are braided and treated with inorganic salt solutions or chemicals to allow it to bend at an angle of 90 degrees when burned. This is the angle that must be achieved when preparing the wick to make sure that the end stays in the flame’s outer mantle and causes to shorten naturally. During this process, the wick must be treated, otherwise it will burn faster. In forming the candle, one of the methods used is extruding the wax with the use of a dye depending on the shape desired. To place the wick at the center, a wick bobbin must be used so that the wax will be formed around the wick.

Preparing the Wax Base

In preparing the wax base, the wax is going to be heated and melted in a clear huge metal kettle. This is a crucial step because when the wax is melted through direct flame, the color will become dark or it may contain small bits of carbon char. The next step is to filter the molten wax so that impurities will be removed. If not, they cannot interfere when the burning process begins. During this time, dyes or perfumes are added. The manufacturing of wax is under a strict purity standard, this is the reason why companies filter their wax to make sure the finished product conforms to the quality standards.

Moulding the Candle

The manufacturing of candles is mainly performed by machines with continuous moulding but manual machines are still used by some companies nowadays. The machines are designed with continuous moulding so that the manufacturing of candles is going to be in groups, usually ranging from 50-500 each load. In making the candle, the entire process takes about 30 minutes each load. Before pouring the wax, the wick is pulled from the tip. The moulds are made of tin and the interior surfaces are polished and slightly tapered so that the finished candle is going to be easier to eject. When the candles are ejected, they are cooled above the temperature of the melting point and then poured in the moulding table placed above the moulds to allow the wicks to thread in the moulds for the next load. After, the wicks are going to be snipped and will start a new process again. The excess wax is trimmed, collected and will be re-used.

From the very start, candles are used not only to give light but to tell time. Back then, the candles serve to measure time but the accuracy is still debatable until now. However, some candles can tell the time, usually in hours. Generally, candles have practical uses, they are:

The electric lights’ intensity is usually given in candlepower. This type of measurement started a long time ago but an ordinary candle cannot tell the accurate standard and the intensity unit is defined in different ways. Originally, candlepower is defined as a luminous intensity of the candle’s horizontal direction at a specified burning size and rate. Today, Candlepower is called Candela, it measures the bulb’s intensity of light which is measured with the use of the bulb.

Household Emergency

In many survival items, supply of candles is always included. However, there is proper handling when using them, there must be proper candle holders, place them away from flammable materials and keep them away from children or pets to avoid untoward accidents. Always remember to never leave them unattended.

Mosquito Repellent

With so many varieties of candles that can be bought, from the most ordinary to the most creative, there are candles that are specially made to repel mosquitoes. These candles are made of citronella which is proven to keep away mosquitoes. They are placed in the backyard or even inside the house. A study was made to prove the effectiveness of citronella candles than the ordinary ones. The results showed that people using the citronella candles had fewer bites by about 42% while the ordinary one registered only 23% less bites.

The manufacturing of candles involves a simple process but it needs the necessary skills and knowledge to come up with quality candles that must conform to the standards set by the industry.
