Description
A thistle plant, Carthamus tinctorius, originally found in Egypt and southern Asia. Safflower was also cultivated in Europe for the oil in its seeds. The flowers of the safflower plant contain a yellow dye and a red dye. The yellow colorant, safflor, is water soluble. The red dye, Carthamin, is extracted from the dried, crushed flower heads with a weak alkali solution after the yellow has been removed with cold water. The yellow color was rarely used while the red safflower was commonly used for dyeing red or pink Silk and Linen since ancient times. It was imported to Europe in the 18th century. Safflower red was used to dye government red tape and may have been used as a pigment. Carthamin is not a permanent color and is sensitive to acids, alkalis, heat, and light.
