black earth (pigment) (black pigment, <pigment by color>, ... Materials (hierarchy name)) |
|
Note: A class of pigments where a variety of both inorganic and organic compounds may be present. Historically, comparatively little is known about which materials were used as black pigments, and in treatises on painting technique, the terms black earth, black chalk and black stone were used interchangeably, whether discussing black pigments or drawing materials. In current technical literature, black earth is generally assumed to be a black shale or chalk, but other bituminous materials and minerals have been identified.

Additional Notes: |
|
| Dutch ..... Een klasse pigmenten waarin zowel anorganische als organische verbindingen kunnen voorkomen. Historisch gezien is er relatief weinig bekend over welke materialen er werden gebruikt als zwarte pigmenten, en in verhandelingen over schildertechniek werden de termen 'zwarte aarde', 'zwart krijt' en 'zwarte steen' door elkaar gebruikt, zowel met betrekking tot zwarte pigmenten als met betrekking tot tekenmateriaal. In de moderne technische literatuur wordt onder zwarte aarde meestal zwarte schalie of krijt verstaan, maar er worden ook andere bitumineuze materialen en mineralen als zodanig aangeduid. |
