Bedford style

Hand-stained bindings produced from a leather sometimes referred to as "fair calf" (a bark tanned calfskin), washed over frequently with a weak solution of potassium carbonate (K 2 CO 3 ), and exposed to light. The staining process took as long as 6 months. In addition to the potassium carbonate, copperas (ferrous sulfate—FeSO 4 ), also known as "green vitroil," was used to produce a particular effect. The carbonate gave a warm brown-toned sprinkle, the sulfate gave a gray, and the two together gave a black. Cf: ETRUSCAN CALF . (94 , 154 , 236 , 347 )
