Bone char is primarily made from cattle and pig bones; however, to prevent the spread of Creutzfeldt–Jakob disease, the skull and spine are no longer used. [2] The bones are heated in a sealed vessel at up to 700 °C (1,292 °F); the oxygen concentration must be kept low while doing this, as it affects the quality of the product, particularly its adsorption capacity.
Bone wax as a sterile preparation for surgery. Bone wax is a waxy substance used to help mechanically control bleeding from bone surfaces during surgical procedures.. It is generally made of beeswax [1] with a softening agent such as paraffin or petroleum jelly and is smeared across the bleeding edge of the bone, blocking the holes and causing immediate bone hemostasis through a tamponade effect.
He discovered that by distilling the lighter, thinner oil products from the rod wax, he could create a light-colored gel. Chesebrough patented the process of making petroleum jelly by U.S. patent 127,568 in 1872. The process involved vacuum distillation of the crude material followed by filtration of the still residue through bone char.
The dripping candle wax sign is a radiologic sign seen on X-rays of bone that indicates melorheostosis (or Leri disease), a rare benign bone disease characterized by bone hypertrophy, dysplasia, and sclerosis. [1] Sclerosis typically affects one side of the cortex of the involved bone, appearing similar to wax melting down one side of a candle. [1]

White sugar (and some brown sugar) produced from sugar cane may be refined using bone char by a few sugar cane refiners. [3] Beet sugar has never been processed with bone char and is vegan. [4] In modern times, activated carbon and ion-exchange resin may be used – see Sugar refinery § Purification.
