(TEXTILES - DYEING). THE THIOGENE COLOURS OF FARBWERKE VORM. MEISTER LUCIUS & BRUNING, HOECHST ON MAIN. ACCORDING TO THE STATE OF THE INDUSTRY IN 1904. New York: H. A. Metz & Co., (1905). Frontispiece of the factory complex in Germany, line illustrations of manufacturing apparatus in the text, and hundreds of swatches of dyed cloths, large and small, in a wide spectrum of colors and patterns. vi,162 pp. Text is in English. 4to., light green cloth sides, gilt title to upper board, publisher's information to lower board, patterned endpapers. Although the backstrip is lacking, the boards are firmly attached. Most leaves have some light dust-soiling at margins and the boards are bowed because the number of mounted samples keeps the individual leaves and the entire volume from closing tightly. A trade catalogue of Thiogene Colors, a subset of the Sulpher Color group, which allowed the direct dyeing of dyestuffs in a greater variety of colors, excepting red, than was formerly possible. The work is divided into two parts; one part deals with the application of Thiogene Colors, and the other describes in detail the various modes of application and the properties of individual colors in the series.
