USES Bone char is used to remove Fluoride from water and to Filter Aquarium water. It is often used in the Sugar refining industry for decolorizing (a process patented by Louis Constant in 1812 ). This leads to worries from Vegans and even Vegetarians , since about a quarter of the sugar in the US is processed using bone char as a filter (about half of all sugar from sugar cane is processed with bone char, the rest with Activated Carbon ). As bone char does not get into the sugar, sugar processed this way is considered Parve / Kosher . Vegans are of varying opinions over whether such sugar can be considered truly vegan. It is used to refine Crude Oil in the production of Vaseline . Bone char is also used as a black Pigment . It is sometimes used for Artistic Painting because it is the deepest available black, though Charcoal Black is often satisfactory and is more often used. Ivory black is an artistic pigment formerly made by grinding charred Ivory in Oil . Today it is considered a synonym for bone char. Ivory is no longer much used because of the expense and Endangered Species issues. |
