Established in 1841, Clayton Street Tannery of Chesterfield is 1 of only 3 tanneries left in the UK.
Specialising in the manufacture of industrial leathers for items such as cricket balls, handbags, floor tiles, saddlery and footwear they use traditional methods similar to those used in places like Morocco.
The skins are first soaked in water to clean and soften them, the hairs and fat are then removed. They are then hung in a tanning tank and are left the length of time depends on whether the tan is to penetrate the leather completely giving it a consistent colour throughout or whether it is purely for the surface. The skins are then dried and passed through pressing machines to the desired thickness.
