Dye-Stuff
27. Dye-Stuff, U. S. Patent 251,163, December 20, 1881, Henrich Baum, Horchst-on-the-Main, Germany, Assignor to Farbwerke, Vormals (formerly) Meister Lucius & Bruning.
This invention is the first synthetic deep scarlet red dyestuff, particularly useful in dying wool. It replaced the natural red dye, Cochenille*, and was widely used.
The model is contained in a corked glass bottle 1" x 1-1/2". The bottle is in excellent condition. Two Patent Office tags remain.
The assignee is now the giant German firm of Farbwerke Hoechst. Hoechst-Celanese is the U. S. subsidiary.
*Cochenille was obtained from female lice living on a thistle growing in the Orient and Central America. Nearly 140,000 lice were required for 1 kg. of dyestuff.
