Sapphire Blue Acid Dye

Concentrated, powdered, hot water dyes that produce the most vibrant possible results on protein fibers including silk, wool, cashmere, alpaca, feathers and nylon. The only acid involved is the vinegar or citric acid you add. A .5-ounce bottle will dye up to two pounds of fiber or yarn depending on the depth of shade desired. In addition to garment dyeing, you can also paint or print with these dyes using steam setting. Extremely brilliant and colorfast, they produce a uniform dye job. The colors are beautiful, pure, transparent and luscious.
