A candle manufacturer is traditionally known as a [[chandlery|chandler]].<ref>{{cite web| url= http://www.thefreedictionary.com/chandler|title=Chandler |publisher=The Free Dictionary By Farlex|accessdate=2012-05-19}}</ref> Various devices have been invented to hold candles, from simple tabletop candle holders, to elaborate [[chandelier]]s.<ref>{{cite web| url= http://www.thefreedictionary.com/chandelier |title=chandelier |publisher=The Free Dictionary By Farlex|accessdate=2012-05-19}}</ref>
For a candle to burn, a heat source (commonly a naked flame) is used to light the candle's wick, which melts and [[vaporizes]] a small amount of fuel, the wax. Once vaporized, the fuel combines with [[oxygen]] in the atmosphere to form a [[flame]]. This flame provides sufficient heat to keep the candle burning via a self-sustaining chain of events: the heat of the flame melts the top of the mass of solid fuel; the liquefied fuel then moves upward through the wick via [[capillary action]]; the liquefied fuel finally vaporizes to burn within the candle's flame.
As the mass of solid fuel is melted and consumed, the candle grows shorter. Portions of the wick that are not emitting vaporized fuel are consumed in the flame. The incineration of the wick limits the exposed length of the wick, thus maintaining a constant burning temperature and rate of fuel consumption. Some wicks require regular trimming with scissors (or a specialized wick trimmer), usually to about one-quarter inch (~0.7 cm), to promote slower, steady burning, and also to prevent smoking. In early times, the wick needed to be trimmed quite frequently, and special candle-scissors, referred to as "[[Candle snuffer|snuffers]]" until the 20th century, were produced for this purpose, often combined with an extinguisher. In modern candles, the wick is constructed so that it curves over as it burns (see picture on the right), so that the end of the wick gets oxygen and is then consumed by [[fire]]—a self-trimming wick.<ref>[http://www.eca-candles.com/design.php?rubrik=29&topnav=6&sprach_id=en&SID=ksqhyfiz European Candle Association FAQ].</ref>

Candles were once made from [[tallow]] and [[beeswax]] until after about 1853, they were made mainly from [[spermaceti]] and purified animal fats ([[stearin]]). Today, most candles are made from [[paraffin wax]].<ref name= Ullmann>Franz Willhöft and Fredrick Horn "Candles" in Ullmann's Encyclopedia of Industrial Chemistry, 2000, Wiley-VCH, Weinheim. {{DOI|10.1002/14356007.a05_029}}</ref> Candles can also be made from [[beeswax]], [[soy]], other [[Wax#Plant waxes|plant waxes]], and [[tallow]] (a by-product of beef-fat rendering).

The candle can be made of
* [[Paraffin wax|paraffin]] (a product of [[petroleum]] refining)
* [[microcrystalline wax]]
* [[stearin]] (now produced almost exclusively from palm waxes though initially manufactured from animal fats)
* [[beeswax]] (a byproduct of [[honey]] collection)
* [[gel]] (a mixture of [[polymer]] and [[mineral oil]])
* some plant waxes (generally palm, [[carnauba wax|carnauba]], [[bayberry]], or [[soybean wax]])
* [[tallow]] (rarely used since the introduction of affordable and cheap wax alternatives)
* [[spermaceti]] (extracted from the head of a [[Sperm Whale]])
The size of the flame and corresponding rate of burning is controlled largely by the [[candle wick]].
Production methods utilize [[extrusion moulding]].<ref name= Ullmann/> More traditional production methods entails [[melting]] the solid fuel by the controlled application of heat. The liquid is then poured into a mould or a wick is repeatedly immersed in the liquid to create a dipped tapered candle. Often [[fragrance oil]]s, [[essential oil]]s or [[aniline]]-based [[dye]] is added.

{{main|Candle wick}}
A candle wick works by [[capillary action]], drawing ("wicking") the melted wax or [[fuel]] up to the flame. When the liquid fuel reaches the flame, it [[vaporize]]s and [[Combustion|combusts]]. The candle wick influences how the candle burns. Important characteristics of the wick include diameter, stiffness, [[Fire resistance|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 [[capillary action|capillarity]] determines the rate at which the melted hydrocarbon is conveyed to the flame. If the capillarity is too great, the molten wax streams down the side of the candle. Wick are often infused with a variety of [[chemical]]s to modify its 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]].<ref name= Ullmann/>

Based on measurements of a taper-type, paraffin wax candle, a modern candle typically burns at a steady rate of about 0.1 g/min, releasing heat at roughly 80 W.<ref name=Hamins>{{cite journal |last1=Hamins |first1=Anthony |last2=Bundy |first2=Matthew |last3=Dillon |first3=Scott E.|date=November 2005 |title=Characterization of Candle Flames |journal=Journal of Fire Protection Engineering |volume=15 |issue= |pages= |page =277 | publisher= |doi=10.1177/1042391505053163 |url=http://fire.nist.gov/bfrlpubs/fire05/PDF/f05141.pdf |format=PDF}}</ref> The light produced is about 13 [[lumen (unit)|lumens]], for a [[luminous efficacy]] of about 0.16 lumens per watt (luminous efficacy of a source) – almost a hundred times lower than an [[incandescent light bulb]].
The [[luminous intensity]] of a typical candle is thus 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.
===Temperatura===
{{see also|Combustion}}
The hottest part of the flame is just above the very dull blue part to one side of the flame, at the base. At this point, the flame is about 1,400 °C. 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. On average, the flame temperature is about 1,000 °C.<ref>[http://www.teachersdomain.org/resource/phy03.sci.phys.matter.onfire/ On Fire – Background Essay], NOVA on Teachers' Domain, WGBH.

The [[color temperature]] is approximately 1,000 K.
===Flaka e qiririt===
[[File:Candle-flame with colour-shift B With zones marked.JPG|thumb|upright|Candle flame with zones marked]]
A candle flame has three distinct regions. The innermost zone, directly above the wick contains wax vapors that have just been vaporized. The middle zone, the yellow portion of the flame is an oxygen depleted zone, where partial oxidation has occurred, but insufficient oxygen exists to burn all of the vapors present. The temperature in this region is hotter than the innermost zone, but cooler than the outer zone. The outer zone is the area where the flame is the hottest and the oxidation process is complete.<ref>{{cite web |url=http://educationalelectronicsusa.com/c/fuels-VIII.htm |title=Fuels Part VIII |publisher=Brodhed Garrett/Frey Resources|accessdate=2012-06-21}}</ref>

According to the U.S. National Fire Protection Association, candles are one of the leading sources of residential fires in the U.S. with almost 10% of civilian injuries and 6% of civilian fatalities from fire attributed to candles.<ref>John Hall, NFPA 2009, http://www.nfpa.org/assets/files//PDF/Research/Fire_overview_2009.pdf.</ref>
A candle flame that is longer than its laminar smoke point<ref>K.M. Allan, J.R. Kaminski, J.C. Bertrand, J. Head, [[Peter B. Sunderland]], Laminar Smoke Points of Wax Candles, Combustion Science and Technology 181 (2009) 800–811.</ref> will emit [[soot]]. Soot inhalation has known health hazards. Proper wick trimming will substantially reduce soot emissions from most candles.
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. When placed over the flame the oxygen supply is cut off. They were used daily when the candle was the main source of lighting a home, before electric lights were available.
Glass candle holders are sometimes cracked by thermal shock from the candle flame, particularly when the candle burns down to the end. When burning candles in glass holders or jars, users should avoid lighting candles with chipped or cracked containers, and stop use once 1/2 inch or less of wax remains.
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 1970s. 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.

Candles and candle accessories pose a [[risk]] to [[property]] and people. [[Risk]] can be reduced by ensuring products comply with [[international standard]]s.

Decorative candle holders, especially those shaped as a pedestal, are called [[candlestick]]s; 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 [[common market|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.
A [[bobèche]] is a drip-catching ring, which may also be affixed to a candle holder, or used independently of one. They can range from ornate metal or glass, to simple plastic, cardboard, or wax paper. Use of paper or plastic bobèches is common at events where candles are distributed to a crowd or audience, such as Christmas carols or other concerts/festivals.
===Candle followers===
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:
* To contain the melted wax – making the candle more efficient, avoiding mess, and producing a more even burn
* As a decoration – either due to the ornate nature of the device, or (in the case of a glass follower) through light dispersion or colouration
* And sometimes to shield the flame from wind.
Candle followers are often found in churches on [[altar candle]]s.

{{main|Candle snuffer}}
Candle snuffers are instruments used to extinguish burning candles by smothering the flame with a small metal cup that is suspended from a long handle, and thus depriving it of oxygen. An older meaning refers to a scissor-like tool used to trim the wick of a candle. With skill, this could be done without extinguishing the flame. The instrument now known as a candle snuffer was formerly called an "extinguisher" or "douter".
==Etimologjia==
The word candle comes from Middle English ''candel'', from Old English and from Anglo-Norman ''candele'', both from Latin ''candla'', from ''candre'', to shine.<ref name=Farlex>{{cite web| url= http://www.thefreedictionary.com/candle |title=Candle |publisher=The Free Dictionary By Farlex|accessdate=2012-05-19}}</ref>

{{Main|History of candle making}}
The earliest known candles originated in China around 200 BC, and were made from whale fat. Candles did not appear in Europe or the Middle East until sometime after AD 400, due largely to the availability of olive oil for burning in [[oil lamp|lamps]].<ref name =Malbrough>{{cite book | last = Malbrough | first = Ray T. | title = The Magical Power of the Saints: Evocation and Candle Rituals | publisher = Llewellyn Worldwide | year = 1998 | page = 68 | url = http://books.google.co.uk/books?id=0gc3AMU7U2IC&pg=PA68&dq=candle+making+egypt+3000+beeswax| isbn = 1-56718-456-1}}</ref> The early European candle was made from various forms of natural fat, tallow, and wax.

[[Paraffin wax|Paraffin]] was first distilled in 1830, and revolutionized candle-making, as it was an inexpensive material which produced a high-quality, odorless candle that burned reasonably cleanly. The industry was devastated soon after, however, by the distillation of [[kerosene]] (confusingly also called ''paraffin oil'' or just ''paraffin''). Recently [[resin]] based candles that are freestanding and transparent have been developed, with the claim that they burn longer than traditional paraffin candles. They are usually scented and oil based.
In the Middle Ages in Europe, tallow candles were the most common candle. By the 13th century, candle making had become a guild craft in England and France. The candle makers (chandlers) went from house to house making candles from the kitchen fats saved for that purpose, or made and sold their own candles from small candle shops.<ref>{{cite web| url= http://www.candles.org/about_history.html|title=History of candles|publisher=National Candle Association |accessdate=2012-05-19}}</ref>

With the fairly consistent and measurable burning of a candle, a common use was to tell the [[time]].

In the days leading to Christmas some people burn a candle a set amount to represent each day, as marked on the candle.

Before the invention of [[electric light]]ing, candles and oil lamps were commonly used for illumination. In areas without electricity, they are still used routinely. Until the 20th century, candles were more common in northern [[Europe]]. In southern Europe and the [[Mediterranean]], oil lamps predominated. In the developed world today, candles are used mainly for their aesthetic value and scent, particularly to set a soft, warm, or romantic ambiance, for emergency lighting during electrical [[power failure]]s, and for religious or ritual purposes. [[Scent]]ed candles are used in [[aromatherapy]]. Some have even gone so far as to make candles scented with racing two-stroke motorcycle oil.<ref name=motovore/>

Candle wax can be made of a few different substances. Paraffin is the most common and cheapest type of wax. Soy is a paraffin alternative that was created to be better for the environment. It is softer and usually has a low melting point. Beeswax is the most expensive and hardest to find. Gel wax is made of mineral oil and resin.
