The pictures illustrate the series of stages involved in the leather production process.
From the general perspective, the process consists of twelve sequential steps, commencing with the arrival of raw animal hides and culminating in the application of wax to the finished leather.
Initially, raw animal skins are transported from farms to factories for processing. Once delivered, they are sorted according to size before being trimmed manually to remove any unwanted edges. Salt is then added to the skins, after which they are left to cure for a period of 36 days to prevent decay. The cured hides are subsequently soaked in water for between 12 and 24 hours to rehydrate them and make them more pliable. Following this, any remaining hair is removed with a knife, ensuring a smooth surface for later stages.
The next phase involves chemical treatments. The hides are pickled with a mixture of salt and acid, then tanned in chemicals for 48 hours to preserve and strengthen the material. They are subsequently coloured and softened using a combination of colouring additives and oils. Once treated, the leather is dried using a fan to remove excess moisture. In the final step, wax is applied manually to enhance durability, improve water resistance, and give the leather a polished appearance.
