Leather, where the hair remains on the leather skin.
Most leather is processed without hair.

- Loosening of meat and fat residues for removal.
- Removal of proteins that would affect the leather quality.
- Removal of fat in the skin.
- Swelling of the leather fibers.
- Open the skin structure, so that the fibers loosen and the tannins can be well connected.
Liming in the drum. - After liming the next working steps are fleshing and splitting.
In the past, liming was done with ashes and water.
