What is the difference between calfskin and wet-blue?
The term skin refers to a young animal, generally under 1 year old (e.g., chicken skin, lambskin, sheepskin, goatskin, etc.). The term hide is used for animals more than 1 year old. A calf is a young cow.
Wet-blue is a half-finished leather. It has undergone a chemical process known as chrome tanning, which makes it blue, and it is called wet because it has been in water.
Otherwise, it makes no difference whether it comes from a cow, bull, calf, water buffalo, etc. If it has been chrome-tanned, it is referred to as wet-blue.
Is the entire calfskin processed?
Yes, the calfskin is processed as a whole. The decision may be made at the tannery to halve it due to the size of the machines. This is also determined by the destination of the skin. The skin is not halved for furniture leather, as the surface from a single piece is desired.
What happens to the skin of the calf’s head?
The head skins are salted in a vat and taken away in bulk. Quality is not assessed – only the shape of the head needs to be maintained. The head skins are primarily shipped to China, where they are made into work gloves, small leather goods and children’s shoes.
What type of salt is used in preservation?
There are various types of salt, but rock salt or sea salt is used for skins and hides. For hides destined for South Korea, the salt must contain 2% sodium carbonate because of veterinary regulations in that country.
How long should a skin be stored before it can be processed?
Skin storage can vary from one country to another because of veterinary regulations. However, export to most countries requires 14 days.
How are the skins selected?
The skin is evaluated overall in terms of slaughter damage, grain damage or a combination of both. Slaughter damage refers to felt damage and holes. Grain damage includes lice, ringworm, transport damage, etc. The location and amount of damage determines the selection.
Are skins from black as well as red-and-white calves processed?
Black and red-and-white skins are processed interchangeably and are not separated.
