semi-chrome tannage
A complete vegetable tannage followed by retannage
by the chrome method. In this particular tannage,
most of the available space between the protein
chains of the skin will be occupied by the large
vegetable tannin molecules, consequently, unless
the vegetable tannage is heavily stripped out, the
principal effect is likely to be the coordination
of chromium with the vegetable tannins. so that
the characteristics of the leather will tend to
approximate those of a vegetable tanned leather.
Cf: CHROME RETAN .
