A distinctive feature or quality that makes an item stand out from its surroundings; a piece upholstered in Edelman leather stands out, changes a room, creates a mood, and enhances the quality of a setting with a special look away from the ordinary.
Aniline (ANN-uhh-lin) Dyeing
Process of coloring leathers throughout with transparent dyes. The formulas for these dyes are precious to our professional dyers. Aniline dyes are challenging to work with and expensive but penetrate thoroughly to ensure the leather wears in, not out.
Leather that has been dyed through with aniline dyes. Aniline leather is sometimes topped with a protein, resin, or lacquer protective coating. It may also be waxed.
Light application of one color over another, usually a darker color over a lighter color, to create highlights and a special antique-appearing patina.
Breakdown of a hide due to bacteria.
Convex wooden frame where hides are placed to hand-trim excess waste.
Part of a hide below the belly line that passes through the front break and below the back break; the underside and upper part of the legs of an animal.

Beating a salted hide to rid it of loose salt in the hair.
Transfer of materials or colors across surfaces that have come in contact with each other.
Flaw or mark that hurts the appearance of a hide. Blemished hides are often used in mass production tanneries where they are sanded to remove blemishes, losing their natural grain and beauty. Edelman buys only the best European hides, so our leather is natural, unblemished, and remains closer to its beautiful, natural state.
Often seen as “in the blue” which refers to the light blue color of hides that have been chrome-tanned.
Dulling or mottling of a leather’s finish due to condensing moisture during the drying process.
Description of stiff, inflexible leather.
Leather fibers that have been bonded together with latex.
An advantage of full-grain leather and a pigment-free dying process, which leaves the grain and pores of a hide intact. Breathability lets the leather adjust to its climate and ultimately produces a better, more luxurious leather.
Application of a concentration of crystallized dyes to add a metallic sheen to the leather.
Process of applying dyes to the top of the leather with a brush.
Part of the sueding process to remove the top surface of the grain.
Center Cut Suede
Suede made from split leather trimmed to leave the bends and shoulder, the best parts of the hide.
Soft, flexible leather usually made with oil-tanned sheep or lamb skin.
Tannage that uses naturally-occurring and safe Chromium III to provide leather with fluids from minerals, rather than plants. It is the most common way of tanning today. Leather responds to chrome in ways that create softness, lighter weights, and gorgeous ranges of color. After tannage, the leather fibers are removed and formed into bricks which can then be turned into recycled, bonded leather and sold for scrap use such as belts, bags, etc.
NOTE: Our tanneries NEVER use Chromium VI, which is toxic and contains carcinogens, and is common in metal plating. Chromium III is safe in tannage. There are NO environmental restrictions from any organization on its use. Few tanneries specialize in providing chrome-free leather. There is no environmental benefit to chrome-free leathers compared to properly-tanned Chrome III leathers. 100% vegetable-tanned leather is the closest to chrome-free leather.
Use of chrome and vegetable tanning to produce a supple hide.
Sometimes also called enhanced, top grain, snuffed, buffed, or polished leather. Corrected hides have their natural grain sanded off, including all natural characteristics, as well as brands, scars, damaged grain, and wrinkles. Large amounts of pigments, instead of aniline dyes, are then used to cover the new surface of the leather and a heavy embossing is pressed on the pigmented surface to recreate a grain. Corrected hides will not grow old gracefully and develop beautiful unique patinas, like natural leather. Instead, the pigment finish will crack and wear out instead of wearing in.
Artists who are highly-skilled and knowledgeable in particular trades or crafts. Edelman teams with these professionals because of their skills, often handed down through generations, in the arts of tanning and dyeing.

Method of curing in which hides are covered in salt and then dried.
Record taken during the dyeing process to identify product that received its coloration in the same drum/vat at the same time. Manufacturers assign each lot a unique identification number and stamp it on the label before shipping.
Art of coloring hides in aniline dyes, either by spraying, hand-rubbing, or immersion. The purpose of dyeing leather is twofold. First, if penetration is complete, the leather will wear to its same color. Second, the closer the color of the unfinished leather is to the desired end color, the less finish will be necessary to achieve the exact color wanted. And the less finish used, the more natural and beautiful the leather will be. The formulas of our professional dyers, who use oak drums for immersing hides, are precious. We air-dry our hides slowly, placing wet hides on drying frames, getting just the right amount of stretch, never under- or overstraining the wet hides. Nothing takes color as beautifully or vividly as a natural leather hide. Aniline dyes are expensive, temperamental, and require much individual attention. The entire process can take anywhere from six hours to three days.
Leather with a unique design or imitation of full grain characteristics.
Process in which a design is added to a leather’s surface by pressure to alter or enhance the surface, resulting in imitation grain or unique patterns.

The distinctive pore and wrinkle pattern that gives the hide its character and feel; may be either natural or embossed.
All Edelman leathers are GREENGUARD Certified (note: tiles for floor application only). The GREENGUARD Certification Program offers assurance that products designed for use in indoor spaces meet strict chemical emissions limits. This contributes to improved air quality where GREENGUARD Certified products are used and helps create healthier interiors. In fact, we did not need to change our leather production processes in order to be certified. 100% of our hides originate in Europe, where EU regulations for leather tanning are the most stringent in the world. Hides from outside the EU are likely of lesser quality and considered to be less environmentally-sound.

Where the embossing plates meet and are occasionally visible.
Leather that has been pressed between heated metal plates under high pressure, often used for furniture leather to cover imperfections.
