The Manufacturer and Builder 5, 1876
A new yellow dye has been named Georgine by M. Singer, of Tournai. It is said to be easily fixed upon all kinds of fibers, needing no mordant with silk and wool, but with cotton it required previous treatment with alum, or passage through a cold or lukewarm sumac bath. For printing upon wool, cotton, and half-wool, it is thickened with gum-water. It may also be employed to bring out the colors of turmeric, fustic, and picric acid, and affords mixed colors of remarkable purity, with other dyestuffs.
