Pioneers of the 1800s used molds to make candles. Candles were a necessity in the days before electricity and the light bulb and a popular source of light after the sun went down. Pioneer women had to make their own candles. Up until about the 1850s candles were made of tallow from animal fat. Making candles was a long process. It would begin with boiling meat over a hot fi re, to separate the animal fat from the meat and bones. When the fat, called tallow, became liquid it was ready to be poured into a mold. The mold had to have a wick inserted before the tallow could be poured into it. When the tallow cooled, the candles were removed.
