A candle manufacturer is traditionally known as a chandler.

A candle for light or heat
Almost everyone loves a candle you can’t deny it.
Candles for myriad of uses, whether for light, spreading scent, setting a mood or decoration.
Candles make great personalized gifts, and each candle is completely different in color, size, scent, shape and more.
Candles are one of the simplest crafts you can do at home and without blowing a fortune.
Children make candles at camps, people make candles for special events as keepsakes, candles are a great way to spend time with family.
You can make candles no matter what the weather’s like or what’s in style.
You may not think about it, candles are used for light and sometimes a source of heat, consisting of a solid block of wax (fuel) and an embedded wick to ignite fuel.
Most candles are made from paraffin.
Candles can also be made from beeswax, soy and other plant waxes, and tallow (a by-product of beef-fat rendering).
Gel candles are made from a mixture of paraffin and plastic.
Various devices have been invented to hold candles from simple tabletop candle holders to elaborate chandeliers.
The heat of the match used to light the candle melts and vaporizes a small amount of fuel.
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…
And the liquefied fuel is then vaporized to burn within the candle’s flame.
The burning of the fuel takes place in several distinct regions (as evidenced by the various colors that can be seen within the candle’s flame).
Within the bluer regions, hydrogen is being separated from the fuel and burned to form water vapor.
The brighter, yellower part of the flame is the remaining carbon being oxidized to form carbon dioxide.
As the mass of solid fuel is melted and consumed, the candle grows shorter.
Portions of the wick that are not evaporating the liquid 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 you can use a specialized wick trimmer), usually one-quarter inch (6 mm) to promote slower steady burning and also to prevent smoking.
Remember, the humble candle created the light bulb.
