CARTHAMUS tinctorius. SAFFLOWER. The Seeds. These have been celebrated as a cathartic: they operate very slowly, and for the most part disorder the bowels, especially when given in substance; triturated with aromatic distilled waters, they form an emulsion less offensive, yet inferior in efficacy to more common purgatives. CENTAUREA Cyanus. BLUE-BOTTLE. The Flowers.
SILK DYES. Silk is usually dyed red with cochineal, or carthamus, and sometimes with Brazil wood. Archil is employed to give silk a bloom, but it is seldom used by itself, unless when the colour wanted is lilac. Silk may be dyed crimson, by steeping it in a solution of alum, and then dyeing it in the usual way in a cochineal bath.
In Carthamus and some other Compositae the central achenes alone are furnished with a pappus; and in Hyoseris the same head yields achenes of three different forms.
Poppy colour, cherry, rose, and flesh colour, are given to silk by means of carthamus. The process consists merely in keeping the silk as long as it extracts any colour, in an alkaline solution of carthamus, into which as much lemon juice has been poured, as is sufficient to give it a fine cherry red colour.
COW-PARSLEY. The umbels produce a yellow colour, and the juice of the other parts of the plant a beautiful green. CARTHAMUS tinctorius. SAFFLOWER. The radius of the corolla, prepared with an acid, affords a fine rose-coloured tint. CENTAUREA Cyanus. BLUE-BOTTLE. The juice of the corolla gives out a fine blue colour. COMARUM palustre. MARSH-CINQUEFOIL. The dried root forms a red pigment.
Safflower: This vegetable dyeing material, for producing pink colours on cotton without the aid of a mordant, consists of the petals of the flower of carthamus tinctorius. The residue after washing free from acid is treated with a dilute solution of soda crystals, and the liquid is then precipitated by an acid.
