Publisher's Synopsis
Excerpt from Leather for Libraries
HE section of the leather trade to which this Handbook relates is that concerned in the manu facture of light leathers tanned with a pale tannage preparatory to being dyed. Bark and most other vegetable tanning substances leave a colour on the skin which cannot be removed without detriment to the durability of the leather; the retention of the colour, however, detracts from the purity of the final colour imparted by the dye. The reputation in the past of the sumach-tanned Spanish leather was founded upon this peculiar property of sumach of leaving the skin white, and on this point the wisdom, of the ancients has been justified by the results of an exhaus tive series of experiments conducted by the Society of Arts' Committee, which have given to sumach the first place in the list of tannages for light leathers.
