Chrome tanning is faster than vegetable tanning (less than a day for this part of the process) and produces a stretchable leather, which is excellent for use in handbags and garments. The compounds that are used as vegetable tanning agents instead of chromium (III) in Tärnsjö are tannins extracted from the mimosa tree.
