	Synthetic Bone Ash
		Murlin Chemical Synthetic Bone Ash is a synthetic mold release agent for use in casting non-ferrous metals.
		While this water is being agitated, the desired amount of synthetic bone ash is added at a uniform rate consistant with complete dispersion of the dry solids.
		Slurries of synthetic bone ash are used at densities varying from 8 degrees Be to 24 degrees Be.

		The bone is then treated to remove glue, which is processed and upgraded for use in normal applications where glue is used, and also for the sizing of expensive paper.
		The raw bone which is left after the meat and glue have been extracted is then heated to about 1000 C at which temperature any residual organic material is burned off and the structure of the bone is changed to form suitable for the manufacture of bone china.
		Prior to use the bone is finely ground with water before inclusion in the bone china body and it is calcined bone which gives traditional English bone china its translucency and whiteness.

	Bone ash - Wikipedia, the free encyclopedia
		Bone ash is the white, powdery ash left from the burning (calcination) of bones.
		It is commonly used in fertilizers, polishing compounds, and in making ceramics (such as bone china).
		Synthetic bone ash has also found use as a mold release agent for the casting of non-ferrous metals such as copper.

	Production of bone china - Patent 4219360
		A method of preparing bone ash, which comprises degelatinizing and calcining animal bone, steeping the bone ash in an aqueous solution of B.sub.2 O.sub.3 or a substance which on heating is converted to B.sub.2 O.sub.3 whereby B.sub.2 O.sub.3 or its precursor is absorbed or adsorbed onto the bone ash, and calcining the bone ash.
		The boron-containing material may be bound to the bone ash by being fused or sintered or calcined with calcined bone, or by being calcined with degelatinized bone so that the calcination simultaneously converts the bone to bone ash and binds the boron-containing material to it.
		It is well-known that bone ash calcium phosphate has a high surface area and therefore a high liquid absorption capacity, but is has been found that the porosity and internal surface area of degelatinized but uncalcined bone are adequate to accept sufficient boric acid or borate salt solution for the practice of this invention.

	Bone china - Wikipedia, the free encyclopedia
		Bone china is type of porcelain body first developed in Britain in which calcined ox bone, bone ash, is a major constituent.
		The first use of bone ash in ceramics is attributed to Thomas Frye in 1748 to make a type of soft-paste porcelain.
		In the late 18th century, Josiah Spode undertook further developments, and subsequently popularised it, by mixing it with china clay, kaolin and China stone to compete with the imported Oriental porcelain.

	Evaluation of Bone Mineral Content in Equine Cadavers and Pregnant Mares
		Bone biopsy techniques may prove to be a useful tool in the future for the quantitative analysis of mineral status in the horse.
		Therefore, the purpose of this study was to determine the bone composition of the twelfth rib and compare the BMC between the rib and third metacarpal of the horse.
		The difference in percent ash and phosphorus between the metacarpal and the rib appears to be due to the composition of the individual bones.

	Bone China
		Bone china is a form of hard paste porcelain because it is a mixture of 25% china clay, 25% Cornish stone, 50% bone ash in its standard formula.
		Bone China is extremely hard, and is stronger than hard-paste porcelain (due to the addition of the ox bone ash) and easier to manufacture.
		The amount of calcined ox bone also allows the addition of more colourful patterns (or more colours to stain the china), thus bone china is usually has most the most exquisite patterens of all china, and those usually are the more expensive and costlier ones.

		Historically, bone charcoal has been used for a variety of purposes for several thousand years, but it is in the dry climate of Egypt that the earliest records of the application of bone charcoal are to be found.
		However, it was not until 1811 that the decolorizing properties of bone charcoal were fully recognized when a French pharmacist by the name of M. Figuier, made this observation while preparing a shoe-fl from honey, vinegar and finely ground animal charcoal.
		Indeed, bone charcoal has continued to be used for this purpose over the years in many countries throughout the world.

		It is fired at about 1400 degress C. Bone China, on the other hand, is a mixture of this porcelain mixture and about 40 or 50 percent bone ash.
		The bone ash serves to whiten and slightly strengthen the porcelain, while reducing the necessary firing temperature by about 150-200 degrees C. Bone china was invented in England in the late eighteenth century, and was apparently superior in strength, translucency, thinness, and whiteness to the porcelain then being produced in Europe.
		I heard from a porcelain collector that most porcelain made today for dinnerware is bone china, though actual bones are apparently no longer generally used; instead they use the pure chemical, calcium carbonate, that is the important ingredient from the bones.
