Answered Sep 17, Important characteristics of the wick include diameter, stiffness, fire-resistance , and tethering. A candle wick is a piece of string or cord that holds the flame of a candle. Commercial wicks are made from braided cotton. The wick's capillarity determines the rate at which the melted hydrocarbon is conveyed to the flame.
A Candle Seesaw Balancing Act - Scientific American
If the capillarity is too great, the molten wax streams down the side of the candle. Wicks are often infused with a variety of chemicals to modify their burning characteristics. For example, it is usually desirable that the wick not glow after the flame is extinguished. Typical agents are ammonium nitrate and ammonium sulfate. Based on measurements of a taper-type, paraffin wax candle, a modern candle typically burns at a steady rate of about 0.
The luminous intensity of a typical candle is approximately one candela.
The SI unit, candela, was in fact based on an older unit called the candlepower , which represented the luminous intensity emitted by a candle made to particular specifications a "standard candle". The modern unit is defined in a more precise and repeatable way, but was chosen such that a candle's luminous intensity is still about one candela.
The hottest part of a candle flame is just above the very dull blue part to one side of the flame, at the base. However note that this part of the flame is very small and releases little heat energy. The blue color is due to chemiluminescence , while the visible yellow color is due to radiative emission from hot soot particles.
The soot is formed through a series of complex chemical reactions, leading from the fuel molecule through molecular growth, until multi-carbon ring compounds are formed. The thermal structure of a flame is complex, hundreds of degrees over very short distances leading to extremely steep temperature gradients. A candle flame is formed because wax vaporizes on burning. A candle flame is widely recognized as having between three and five regions or "zones":. The main determinant of the height of a candle flame is the diameter of the wick.
This is evidenced in tealights where the wick is very thin and the flame is very small. Candles whose main purpose is illumination use a much thicker wick. One of Michael Faraday 's significant works was The Chemical History of a Candle , where he gives an in-depth analysis of the evolutionary development, workings and science of candles.
According to the U. The liquid wax is hot and can cause skin burns, but the amount and temperature are generally rather limited and the burns are seldom serious. The best way to avoid getting burned from splashed wax is to use a candle snuffer instead of blowing on the flame.
A candle snuffer is usually a small metal cup on the end of a long handle. Placing the snuffer over the flame cuts off the oxygen supply. Snuffers were common in the home when candles were the main source of lighting before electric lights were available. Ornate snuffers, often combined with a taper for lighting, are still found in those churches which regularly use large candles. Glass candle-holders are sometimes cracked by thermal shock from the candle flame, particularly when the candle burns down to the end.
A former worry regarding the safety of candles was that a lead core was used in the wicks to keep them upright in container candles.
Without a stiff core, the wicks of a container candle could sag and drown in the deep wax pool. Concerns rose that the lead in these wicks would vaporize during the burning process, releasing lead vapors — a known health and developmental hazard. Lead core wicks have not been common since the s. Today, most metal-cored wicks use zinc or a zinc alloy , which has become the industry standard. Wicks made from specially treated paper and cotton are also available. International markets have developed a range of standards and regulations to ensure compliance, while maintaining and improving safety , including:.
Decorative candleholders, especially those shaped as a pedestal, are called candlesticks ; if multiple candle tapers are held, the term candelabrum is also used. The root form of chandelier is from the word for candle, but now usually refers to an electric fixture. The word chandelier is sometimes now used to describe a hanging fixture designed to hold multiple tapers. Many candle holders use a friction-tight socket to keep the candle upright.

In this case, a candle that is slightly too wide will not fit in the holder, and a candle that is slightly too narrow will wobble. Candles that are too big can be trimmed to fit with a knife; candles that are too small can be fitted with aluminium foil. Traditionally, the candle and candle holders were made in the same place, so they were appropriately sized, but international trade has combined the modern candle with existing holders, which makes the ill-fitting candle more common. This friction tight socket is only needed for the federals and the tapers. For tea light candles, there are a variety of candle holders, including small glass holders and elaborate multi-candle stands.
The same is true for votives. Wall sconces are available for tea light and votive candles. For pillar-type candles, the assortment of candle holders is broad. A fireproof plate, such as a glass plate or small mirror, is a candle holder for a pillar-style candle. A pedestal of any kind, with the appropriate-sized fireproof top, is another option. A large glass bowl with a large flat bottom and tall mostly vertical curved sides is called a hurricane.

The pillar-style candle is placed at the bottom center of the hurricane. A hurricane on a pedestal is sometimes sold as a unit. These are glass or metal tubes with an internal stricture partway along, which sit around the top of a lit candle. As the candle burns, the wax melts and the follower holds the melted wax in, whilst the stricture rests on the topmost solid portion of wax. Candle followers are often deliberately heavy or weighted to ensure they move down as the candle burns lower, maintaining a seal and preventing wax escape.
The purpose of a candle follower is threefold:.
