Carbon black

The lampblack was in former times a means of blackening. He served as a black dye for book, stone and copper inks, mixed with lard as shoe polish and as a color additive in distemper. Because he served as a sealing material of hulls as raw material, were the main buyers of German, especially the Thuringian Kienrußbrenner United Kingdom and the Netherlands ( See also section on the history Crawinkels ).

As a precursor processed the Teerschweler in kilns resinous softwoods. The wood was burnt smoldering under low air and the smoke passed into the cone-like Rußkammer where the soot settled on the walls of metal, linen or wool. The charred wood was sold as charcoal.
