WHALES, INSECTS, AND COWS HAVE ALL BEEN USED TO MAKE CANDLES.
Not all candles are vegan and natural. In the Middle Ages, tallow, a byproduct of cattle fat, was widely used to create candles in Europe.
Wax derived from seeds and insects have also been used to make candles. Even spermaceti from sperm whales and different plants were used to make it. Paraffin, beeswax, soy, and other waxes are currently used primarily in the production of candles.
