Description

Excerpt from The Influence of Ph on the Deterioration of Vegetable-Tanned Leather by Sulphuric Acid<br/><br/>It is shown that pure vegetable-tanned leathers treated with sul 'phmic acid and aged for two years start to deteriorate at or near ph 3. This was found to be true for 13 different leathers regardless of the kind of vegetable tanning material used, the degree of tannage, the amount of sulphuric acid added to the leather originally, the aging conditions, and the ph of the original leather before being treated with acid. Thus the potential value of a ph measurement for evaluating leather with respect to harmful acidity is indicated. Seri ous consideration of its use is advocated with limiting values for dif ferent leathers to begoverned by the length of service expected and the conditions of use.
