What is full grain or corrected grain leather?
Leather is a highly desirable furniture upholstery material, priced for its durability and comfort — the ultimate symbol of natural beauty and luxury.
The difference between Corrected Grain and Full Grain
Corrected grain leather is also referred to as CG leather. Over the years, scars and markings will appear on the skin as the animal is exposed to the African field.
Tanneries try to get rid of these markings with the following process: Firstly, deep holes and marks are filled with a leather filler. The top layer of the skin then gets shaved away to eliminate all remaining marks. The leather is now without any markings, but it is also stripped of its natural grain.
Big, heated metal plates are used to emboss a grainy print on the leather. After the leather has gone through this process, it is called corrected grain as opposed to full grain leather, which has not gone through this process. It looks uniform because most of the natural grain has been removed, and it is given a semi-aniline-coated finish or, more often, pigmented dye (protective dye).
Full-grain leather is the most natural, durable, and expensive leather used for high-end upholstery.
Full-grain leather has only been dyed in a drum and has no pigmentation on top. Removing the animals’ hair leaves the leather with its natural grain, marks, and scars visible.
Full-grain leather is usually treated with a transparent vegetable dye called “aniline” or dyed and then coated called “semi-aniline”. This finishing process helps protect the colour and makes leather suitable for manufacturing furniture and other products. The appearance of full-grain leather is very natural and alive, but it is slightly less colourfast and stain-resistant than semi-aniline leather.
