Glossary
The process of melting raw beeswax (cappings, burr comb, and old comb) and separating it from honey residue, propolis, and debris to produce clean, pure beeswax suitable for candles, cosmetics, food wraps, and other products. Properly rendered beeswax is golden yellow, smells of honey, and is free of visible impurities.
Raw beeswax from the hive contains honey, pollen, propolis, cocoon casings, and other debris that must be removed. The basic process involves melting the wax in water (which separates honey and water-soluble impurities), straining through cheesecloth or a fine mesh, and allowing the wax to cool and solidify on top of the water. The debris settles to the bottom of the wax disc and can be scraped off.
For cleaner wax, repeat the melt-and-strain process multiple times. Each cycle removes more impurities. Commercial-grade beeswax may go through 3-5 filtration cycles. For cosmetic-grade beeswax, final filtration through paper coffee filters (supported on a wire mesh) while the wax is liquid removes the finest particles.
Beeswax has a melting point of 143-151 degrees Fahrenheit (62-66 degrees Celsius) and a flash point of approximately 490 degrees Fahrenheit (254 degrees Celsius). While the flash point is high, beeswax should never be heated over direct flame or left unattended. Use a double boiler or water bath method for safe, controlled melting.
Dedicate specific equipment to wax rendering: a stainless steel or enamel pot, stainless steel utensils, and cheesecloth for straining. Beeswax is extremely difficult to remove from surfaces and will ruin household cooking equipment. Many beekeepers use a crock pot dedicated to wax rendering.
Pure beeswax melts between 143 and 151 degrees Fahrenheit (62-66 degrees Celsius). Heat slowly and do not exceed 185 degrees Fahrenheit, as higher temperatures darken the wax and degrade its quality. Never heat beeswax over direct flame.
Yes, but dark comb (which has been used for brood rearing and contains accumulated cocoons, propolis, and debris) yields less wax per pound than fresh cappings. The resulting wax is darker and may require additional filtering. It is perfectly usable for candles and non-cosmetic purposes.
Fresh cappings are the highest quality wax source. One pound of dry cappings yields approximately 0.8-0.9 pounds of rendered wax. Old brood comb yields far less, approximately 0.3-0.5 pounds per pound of comb, because much of the weight is cocoon material.
