Bone Black Strong Tinting Strength For Black Pigment

 

Product Description:

Bone Char – Product Introduction
Bone Char is a black, porous, carbon-rich material produced by the pyrolysis of animal bones under low-oxygen conditions. It consists primarily of calcium phosphate (Ca5(PO4)3OH) and amorphous carbon, giving it a unique combination of adsorptive capacity and chemical stability.

 

Chemical Composition:
Calcium Phosphate (Ca5(PO4)3OH): ~70-80%
Carbon (Fixed Carbon): ~10-15%
Other Components: Trace minerals and moisture

 

Key Industrial Applications of Bone Char
1, Sugar Refining

2, Water Purification & Filtration

3, Gas & Air Filtration

4, Pigment and Ink Manufacturing

 

Bone Black, also known as Bone Charcoal, is a deep black pigment with exceptional tinting strength and high opacity. Produced by carbonizing animal bones at high temperatures, it contains primarily carbon along with small amounts of calcium phosphate. Its fine particle size and natural composition make it ideal for producing rich, matte black tones in various applications, including paints, inks, coatings, and artistic media. Bone Black offers excellent dispersion, stable performance, and strong resistance to fading, making it a preferred choice for formulators seeking intense black color with natural origins. It is widely used in traditional art, industrial coatings, and specialty black formulations.

 

Bone black is a classic black pigment. It is a dark, opaque black pigment that has a strong tinting strength, meaning that a little bit goes a long way in creating rich, dark colors.

One of the key characteristics of bone black is its strong tinting strength, which makes it an ideal choice for creating deep, bold black tones in artwork. This is especially useful for artists who want to achieve dramatic contrast and depth in their paintings or drawings. Because of its intense black color, bone black can be easily mixed with other colors to create a wide range of shades and tones.

Bone black is made from charring bones, usually those of cattle or pigs, in a controlled environment. The bones are heated to high temperatures until they turn into a charred, black residue, which is then ground into a fine powder. This powder can then be mixed with a binder, such as linseed oil or acrylic medium, to create a paint or ink that can be applied to a variety of surfaces.

In addition to its strong tinting strength, bone black is also known for its permanence and lightfastness. This means that artwork created with bone black pigment will not fade or change color over time, ensuring that your work will last for years to come. It is also resistant to chemicals and solvents, making it a durable choice for artists who want their work to withstand the test of time.
