Standard Specification for Bone Black Pigment
ABSTRACT
This specification covers bone black, ivory black, or drop black pigment. The pigment may be in dry form or in aqueous dispersion. Dry pigment shall be made by the calcinations of bones, unmixed with any other substance. Dry pigment shall compose of ash, ash insoluble in acids, and coarse particles. Pigment in aqueous dispersion shall be made by grinding the pigment with water, dispersing agent, biocide, fungicide, pH stabilizer, and defoamer. ASTM test methods shall be conducted for coarse particles, pigment and linseed oil in paste in oil, and mass color and tinting strength.
SCOPE
1.1 This specification covers the pigment commercially known as bone black, ivory black, or drop black. The pigment may be purchased in the dry form or as an aqueous dispersion.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
