bleaching, leather - Bleaching, Leather
bleaching, leather - Fine goods. - In the preparation of the light tinted fancy book covers, and which are sometimes a pinkish white, the leather is immersed in benzine for an hour, for the colouring agents in leather, ferric oleate and tannate are soluble in benzine. After one hour's immersion remove the leather and then evaporate the benzine it carries by gentle heat over a water bath. The leather is then treated with liquid sulphurous acid, or javelle water, or peroxide of hydrogen with ammonia. Care must be used in drying.
