“Tanning experiments carried out with the chromium, iron, aluminium, and calcium salts of Ordoval G yielded leathers which possessed proportionate characteristics of either kind of tannage to the extent to which either material was present.”
“During "tannage," bakelite is formed in the liquid, and practically all solubles originally present are deposited.”
“I've always had sun-loving skin; even the shielding of SPF 45 will not prevent tannage from occurring.”
“Although this layer is removed during tannage, scale slip is a symptom of rot and usually causes damage to the finished hide product.”
“Analysis of this product, using the shake method, gives a tannin content of 16.2 per cent; tanning experiments demonstrated that the time of tannage, using a 2° Bé. solution, was the same as that required by Neradol D, and yielded a leather, the surface of which was reddish-grey, the inner layers being white, but which is otherwise very similar to Neradol D tanned leather.”
“As soon as the tanning matter has completely penetrated the pelt, the total time of tannage is noted, and the velocity with which the tanning matter converts the pelt into leather at that particular concentration is thus obtained.”
“Simple as such a differentiation appears, there are still a number of cases occupying a position between the two referred to, and which we may term _pseudo-tannage_.”
“The tannage may also be effected by exposing pelt saturated with hydroquinone to oxidation by the air.”
“In all cases rapid tannage was observed yielding firm and soft leathers of light brown colour and varying degrees of swollenness.”
“In one respect -- that of its salts -- Ordoval G differs from the Neradols; whereas the chromium and aluminium salts of the latter possess no such tannoid properties as will make the resultant leather exhibit any of the characteristics of either tannage, it is possible to carry out combined tannage with a mixture of Ordoval G and metallic salts.”
