Antiquing: A method of aging the appearance of a hide.
Usually done by hand,
this technique is best suited for full-grain hides.
Corrected Grain: Hides whose original surface pattern or surface structure
has not bee changed.
Full Grain: Leather in which the grain layer or dermis has no been altered. The grain
layer
gives each type of leather its distinctive appearance.
Hand: Industry term for the feel of leather.
Nubuck: A top-grain, aniline dyed leather that is buffed to create a soft nap. Not a true suede, which is made from the less desirable split hide. Especially vulnerable to stains, Nubucks are often lightly finished for protection.
Patina: A natural characteristic that develops on full grain leather through normal use over a period of time.
Pure Aniline: An aniline dyed hide, which has no finish. This is the ultimate leather often referred to as a naked resistance.
Pigmented: Leathers that have been sprayed with a pigmented, opaque finish. This ensures uniformity of shade and resistance to fading.
Pull Up: A look associated with quality leather. A pull up leather is one which, when pulled tight, produces a brilliant burst of color. Pull ups are full aniline leathers that have had an oil or wax application.
Semi Aniline: Leather that has been completely dyed through and has received a nominal amount of manufacturing coated that covers minor surface defects but sufficient enough to conceal the natural characteristics of the skin.
