Candles have cast a light on man's progress for centuries. However, there is very
little known about the origin of candles.
Accounts of candle use date back to ancient times, with Biblical references as
early as the tenth century BC. The earliest known example of a candle—just a
fragment— from the first century AD was found in Avignon, France.
Although it is often written that the first candles were developed as early as
3000 BC in Crete and by the Ancient Egyptians who used rushlights, or torches,
made by soaking the pithy core of reeds in molten tallow, the rushlights had no
wick like a candle. It is the Romans who are credited with developing the wick candle,
using it to aid travelers at dark, and lighting homes and places of worship at night.
Like the early Egyptians, the Romans relied on tallow, gathered from cattle or
sheep suet, as the principal ingredient of candles. It was not until the Middle
Ages when beeswax, a substance secreted by honey bees to make their honeycombs,
was introduced. Beeswax candles were a marked improvement over those made with
tallow, for they did not produce a smoky flame, or emit an acrid odor when burned.
Instead, beeswax candles burned pure and clean. However, they were expensive, and,
therefore, only the wealthy could afford them.
Colonial women offered America's first contribution to candlemaking when they
discovered that boiling the grayish green berries of bayberry bushes produced
a sweet-smelling wax that burned clean. However, extracting the wax from the
bayberries was extremely tedious. As a result, the popularity of bayberry
candles soon diminished.
Candles were widely used in medieval times and they could be found in great halls,
monasteries, churches, cottages, and shops. The simplest (and smelliest) candles -
known as rush light - were made by dipping rushes in leftover kitchen fat.
The growth of the whaling industry in the late 18th century brought the first
major change in candlemaking since the Middle Ages, when spermaceti, a wax
obtained by crystallizing sperm whale oil, became available in quantity. Like
beeswax, the spermaceti wax did not elicit a repugnant odor when burned.
urthermore, spermaceti wax was found harder than both tallow and beeswax.
It did not soften or bend in the summer heat. Historians note that the first
'standard candles' were made from spermaceti wax.
It was during the 19th century when most major developments affecting contemporary
candlemaking occurred. In 1834, inventor Joseph Morgan introduced a machine which
allowed continuous production of molded candles by the use of a cylinder which
featured a movable piston that ejected candles as they solidified.
Further developments in candlemaking occurred in 1850 with the production of
paraffin wax made from oil and coal shales. Processed by distilling the residues
left after crude petroleum was refined, the bluish-white wax was found to burn
cleanly, and with no unpleasant odor. Of greatest significance was its cost - paraffin
wax was more economical to produce than any preceding candle fuel developed.
At the same time, a chemist named Michel Eugene Chevreul made an important discovery.
He realized that tallow was not one substance but a composition of two fatty acids,
stearic acid and oleic acid, combined with glycerine to form a neutral, non-flammable
material. By removing the glycerine from the tallow mixture, Chevreul invented a new
substance called "stearine."
And while paraffin's low melting point may have posed a threat to its popularity,
the discovery of stearic acid solved this problem. Hard and durable, stearic acid
was being produced in quantity by the end of the 19th century. By this period,
most candles being manufactured consisted of paraffin and stearic acid.
With the introduction of the light bulb in 1879, candlemaking declined until the
turn of the century when a renewed popularity for candles emerged.
Candle manufacturing was further enhanced during the first half of the 20th
century through the growth of U.S. oil and meatpacking industries. With the
increase of crude oil and meat production, also came an increase in the by-products
that are the basic ingredients of contemporary candles - paraffin and stearic acid.
No longer man's major source of light, candles continue to grow in popularity and
use. Today, candles symbolize celebration, mark romance, define ceremony, and
accent decor - continuing to cast a warm glow for all to enjoy.
