With the holiday season is in full swing, you may have begun to notice that many individuals are lighting candles. Candles can serve many different purposes in life and can bring a great deal of warmth to those in need of heat. When you look at a candle, you may not realize that they have a strong connection with agriculture.
Many individuals have been credited with the creation of candles and there have been many agricultural products used to make candles. The first candles used by the ancient Egyptians were rushlights (or torches) made by soaking the core of reeds in melted animal fat. Wax made from indigenous insects combined with seeds and rolled rice paper was used to make the candles utilized by the early Chinese. In comparison, the wax extracted from tree nuts was used in Japan, while wax made by boiling the fruit of the cinnamon tree was used in India.
Tallow (or animal fat) was primarily used by early Western cultures to make candles. It wasn’t until the Middle Ages that individuals in Europe began to use beeswax instead. There were many advantages of beeswax over tallow since it burned pure, did not have a smoky flame, and emitted a sweet smell.
Another alternative to using tallow and beeswax came when colonial women began to use berries from the bayberry bush to make candles. Candles made from bayberry bushes produce a sweetsmell and burned clean like beeswax. However, it was extremely tedious to get the wax from the bayberries.
One of the biggest changes in candle-making came in the 1850s when chemists learned how to efficiently separate the waxy substance from petroleum and refine it. This substance was called paraffin wax and was odorless when burned. It was economical to produce and a big leap forward for the candle-making industry.
With plants grown to produce the wax, extracting wax from animal fat, utilizing bees wax, and now using paraffin wax to make candles, you can see the numerous links candles have within the agricultural industry. One final link came in the 1990s when U.S. agricultural chemist began to utilize soybean wax for candles. Soybean wax is softer and is a slower burning wax when compared to paraffin wax.
This holiday season when you are lighting up your candles, remember that they are deeply connected to agriculture. As you light them, remember to stay safe by always using a candleholder specifically designed for candle use and to trim candlewicks to ¼ inch before lighting or re-lighting them.
