Candle in the context of Wax

Traditional medicine (also known as indigenous medicine or folk medicine) refers to the knowledge, skills, and practices rooted in the cultural beliefs of various societies, especially Indigenous groups, used with the intent of treating illness and maintaining health.

In some Asian and African countries, up to 80% of people rely on traditional medicine for primary health care. Traditional medicine includes systems like Ayurveda, traditional Chinese medicine, and Unani. The World Health Organization supports their integration, but warns of potential risks and calls for more research on their safety and effectiveness.

An oil lamp is a lamp used to produce light continuously for a period of time using an oil-based fuel source. The use of oil lamps began thousands of years ago and continues to this day, although their use is less common in modern times. They work in the same way as a candle but with fuel that is liquid at room temperature, so that a container for the oil is required. A textile wick drops down into the oil, and is lit at the end, burning the oil as it is drawn up the wick.

Oil lamps are a form of lighting, and were used as an alternative to candles before the use of electric lights. Starting in 1780, the Argand lamp quickly replaced other oil lamps still in their basic ancient form. These in turn were replaced by the kerosene lamp in about 1850. In small towns and rural areas the latter continued in use well into the 20th century, until such areas were finally electrified and light bulbs could be used.

Brazilian industry has its earliest origin in workshops dating from the beginning of the 19th century. Most of the country's industrial establishments appeared in the Brazilian southeast (mainly in the provinces of Rio de Janeiro, Minas Gerais and, later, São Paulo), and, according to the Commerce, Agriculture, Factories and Navigation Joint, 77 establishments registered between 1808 and 1840 were classified as "factories" or "manufacturers". However, most, about 56 establishments, would be considered workshops by today's standards, directed toward the production of soap and tallow candles, snuff, spinning and weaving, foods, melting of iron and metals, wool and silk, amongst others. They used both slaves and free laborers.

There were twenty establishments that could be considered in fact manufacturers, and of this total, thirteen were created between the years 1831 and 1840. All were, however, of small size and resembled large workshops more than proper factories. Still, the manufactured goods were quite diverse: hats, combs, farriery and sawmills, spinning and weaving, soap and candles, glasses, carpets, oil, etc. Probably because of the instability of the regency period, only nine of these establishments were still functioning in 1841, but these nine were large and could be considered to "presage a new era for manufactures".

Smoke is an aerosol (a suspension of airborne particulates and gases) emitted when a material undergoes combustion or pyrolysis, together with the quantity of air that is entrained or otherwise mixed into the mass. It is commonly an unwanted by-product of fires (including stoves, candles, internal combustion engines, oil lamps, and fireplaces), but may also be used for pest control (fumigation), communication (smoke signals), defensive and offensive capabilities in the military (smoke screen), cooking, or smoking (tobacco, cannabis, etc.). It is used in rituals where incense, sage, or resin is burned to produce a smell for spiritual or magical purposes. It can also be a flavoring agent and preservative.

Smoke inhalation is the primary cause of death in victims of indoor fires. The smoke kills by a combination of thermal damage, poisoning and pulmonary irritation caused by carbon monoxide, hydrogen cyanide and other combustion products.

In combustion, a diffusion flame is a flame in which the oxidizer and fuel are separated before burning. Contrary to its name, a diffusion flame involves both diffusion and convection processes. The name diffusion flame was first suggested by S.P. Burke and T.E.W. Schumann in 1928, to differentiate from premixed flame where fuel and oxidizer are premixed prior to burning. The diffusion flame is also referred to as nonpremixed flame. The burning rate is however still limited by the rate of diffusion. Diffusion flames tend to burn slower and to produce more soot than premixed flames because there may not be sufficient oxidizer for the reaction to go to completion, although there are some exceptions to the rule. The soot typically produced in a diffusion flame becomes incandescent from the heat of the flame and lends the flame its readily identifiable orange-yellow color. Diffusion flames tend to have a less-localized flame front than premixed flames.

The contexts for diffusion may vary somewhat. For instance, a candle uses the heat of the flame itself to vaporize its wax fuel and the oxidizer (oxygen) diffuses into the flame from the surrounding air, while a gaslight flame (or the safety flame of a Bunsen burner) uses fuel already in the form of a vapor.

Candela (symbol: cd) is the SI unit of luminous intensity. It measures the luminous power per unit solid angle emitted in a particular direction. A common wax candle has a luminous intensity of roughly 1 cd.

The word candela is Latin for candle. The old name "candle" is still sometimes used, as in foot-candle and the modern definition of candlepower.

A tealight (also tea-light, tea light, tea candle, or informally tea lite, t-lite or t-candle) is a candle contained in a thin metal or plastic cup so that its wax can melt completely while lit. They are typically small, circular, usually wider than their height, and inexpensive. Tealights derive their name from their use in teapot warmers, but are also used as food warmers in general, e.g. fondue.

Tealights are a popular choice for accent lighting and for heating scented oil. A benefit that they have over taper candles is that they do not drip. Tealights may be set afloat on water for decorative effect. Because of their small size and low level of light, multiple tealights are often burned simultaneously. Longer-burning tealights may be called nightlights. They are also lit for religious purposes.

Traditional medicine (also known as indigenous medicine or folk medicine) refers to the knowledge, skills, and practices rooted in the cultural beliefs of various societies, especially indigenous groups, used with the intent of treating illness and maintaining health.

In some Asian and African countries, up to 80% of people rely on traditional medicine for primary health care.

A candle wick or lamp wick is usually made of braided cotton that holds the flame of a candle or oil lamp. A candle wick works by capillary action, conveying ("wicking") the fuel to the flame. When the liquid fuel, typically melted candle wax, reaches the flame it then vaporizes and combusts. In other words, the wick brings the liquified wax up into the flame to burn. The candle wick influences how the candle burns. Important characteristics of the wick include diameter, stiffness, fire-resistance, and tethering.

A chandelier (/ˌʃændəˈlɪər/) is an ornamental lighting device, typically with spreading branched supports for multiple lights, designed to be hung from the ceiling. Chandeliers are often ornate, and they were originally designed to hold candles, but now incandescent light bulbs are commonly used, as well as fluorescent lamps and LEDs.

A wide variety of materials ranging from wood and earthenware to silver and gold can be used to make chandeliers. Brass is one of the most popular materials, but glass is most commonly associated with chandeliers. Classic glass and crystal chandeliers have arrays of hanging "crystal" prisms to illuminate a room with refracted light. Contemporary chandeliers may assume a more minimalist design, and they may illuminate a room with direct light from the lamps or are equipped with translucent glass shades covering each lamp. Chandeliers produced nowadays can assume a wide variety of styles that span modernized and traditional designs or a combination of both.

A candlestick (or candleholder) is a device used to hold a candle upright in place. Most candlesticks have a cup, a spike (called a "pricket"), or both to secure the candle.

Before the widespread adoption of electricity, candles were carried between rooms using a chamberstick—a short candlestick with a pan to catch dripping wax.

A candelabrum or candelabra (pl. candelabra, candelabras, or candelabrums) is a type of candlestick which has multiple branches to hold several candles as opposed to only one. "Candelabra" can be used to describe a variety of candle holders including chandeliers. However, candelabra can also be distinguished as branched candle holders that are placed on a surface such as the floor, stand, or tabletop. The chandeliers, on the other hand, are hung from the ceiling.

The Romans used the term to describe a form of ornamental lighting, which may be a tall stand that supports a lamp. In Judaism, the menorah and hanukkiah are special kinds of candelabra. Candelabra are also used in churches, in ceremonies such as Tenebrae, in certain Eastern Catholic and Eastern Orthodox Church liturgy such as the dikirion and trikirion. Candelabra in the form of branched candlesticks also became popular in homes as decorative lighting.

The Advent wreath, or Advent crown, is a Christian tradition that symbolizes the passage of the four weeks of Advent in the liturgical calendar of the Western church. It is traditionally a Lutheran practice, although it has spread to many other Christian denominations.

It is an evergreen wreath with four candles, sometimes with a fifth, white candle in the center. Beginning with the First Sunday of Advent, the lighting of a candle can be accompanied by a Bible reading, devotional time and prayers. An additional candle is lit on each subsequent Sunday until, by the last Sunday of Advent, all four candles are lit. Some Advent wreaths include a fifth, Christ candle which is lit on Christmas Eve or Christmas Day. The custom originated in family settings but has also become widespread in public worship.

In Eastern Orthodox and Byzantine-rite Catholic churches, an entrance is a procession during which the clergy enter into the sanctuary through the Holy Doors. The origin of these entrances goes back to the early church, when the liturgical books and sacred vessels were kept in special storage rooms for safe keeping and the procession was necessary to bring these objects into the church when needed. Over the centuries, these processions have grown more elaborate, and nowadays are accompanied by incense, candles and liturgical fans. In the liturgical theology of the Eastern Orthodox Church, the angels are believed to enter with the clergy into the sanctuary, as evidenced by the prayers which accompany the various entrances.

Shabbat candles (Hebrew: נרות שבת, romanized: nerot shevet) are candles lit on Friday evening before sunset to usher in the Jewish Shabbat. Lighting Shabbat candles is a rabbinically mandated law. Candle-lighting is traditionally done by the woman of the household, but every Jew is obligated to either light or ensure that candles are lit on their behalf.

In Yiddish, lighting the candles is known as licht bentschen ("light-blessing") or licht tsinden ("light-kindling").

A votive candle or prayer candle is a small candle, typically white or beeswax yellow, intended to be burnt as a votive offering in an act of Christian prayer, especially within the Anglican, Lutheran, and Roman Catholic Christian denominations, among others. In Christianity, votive candles are commonplace in many churches, as well as home altars, and symbolize the "prayers the worshipper is offering for him or herself, or for other people." The size of a votive candle is often two inches tall by one and a half inches diameter, although other votive candles can be significantly taller and wider. In other religions, such as Hinduism and Buddhism, similar offerings exist, which include diyas and butter lamps.

A yahrzeit candle, also spelled yahrtzeit candle or called a memorial candle, (Hebrew: נר נשמה, ner neshama, meaning "soul candle"; Yiddish: יאָרצײַט ליכט yortsayt likht, meaning "anniversary candle") is a type of candle that is lit in memory of the dead in Judaism.
