Zusammenfassung:Wet hides stripped of colour, biologically stable, untanned, intrinsically insensitive to mildews, containing from 50 to 70% of water, from 5 to 30% of inorganic matter, from 0.5 to 1.5% of Al2O3 and from 85 to 90% of dermic substances. They are obtained by impregnating pickled hides with the aid of a basic aluminium polychloride or polychlorosulphate followed by a basification.
