Leather Definitions
COLOR
Aniline
Leather that has been dyed with a transparent dye which penetrates all the way through the top and back surfaces, allowing all the natural characteristics of the hide to be highlighted.
Semi-aniline
Top-grain leather that is aniline dyed, and has pigment and/or other topical finishes added for enhanced effects or a more even coloration.
GRAIN

Top Grain, top layer
Splits, bottom two layers

Full Grain

Embossed Grain, more uniform texture
The outermost layer of the leather hide, which produces the highest quality leather.
Full GrainTop grain leather that has not been altered and retains its original, natural grain.
GrainThe distinctive pore and wrinkle pattern of a hide; may be either natural or embossed.
SplitsUnderlying layers of the leather hide, not top grain. Used for suede, and may be embossed to simulate top grain.
BondedA reconstituted leather product created by grinding leather scraps and mixing them with bonding agents to create a sheet of material, then embossed with a grain pattern. Often used on leather book covers.
TREATMENT

Corrected

Uncorrected

Buffed
Leather's natural surface texture has been altered to make it more uniform.
UncorrectedLeather's natural surface texture has not been altered in any way; original grain pattern and markings intact.
EmbossedTexture is added to alter or enhance the surface, resulting in uniform grain or unique patterns.
BuffedThe top surface of the hide is sanded to give the leather a soft, velvety feel.
Top CoatA clear protective coating to help resist spills and soiling, making it easier to maintain the appearance of the leather.
ENHANCEMENTS

Sauvage

Pull up effect

Crackle effect

Bonded, leather product
PatinaThe desirable change in appearance of leather due to normal use and time, affecting its color, texture and luster.
SauvageA two-tone or marbled effect created by applying dyes or pigments to create highs and lows in coloration.
Oil-protectedDuring the tanning process, oils are infused into the surface to create a soft, pliable feel. As the leather is pulled, the oils separate, creating variation in color.
Pull UpLeather that shows bursts of color when pulled, often a lighter color. When upholstered, these lighter areas appear where the leather is stretched, such as arms, corners and backs. Creates a naturally aged appearance.
Wax-protectedLeather that has been finished with wax for a smooth feel and burnished luster. Often, the wax will contribute to an aged, crackled look.
CrackleThe finish is applied and milled in such a way that the top layer appears to "crack" revealing the color underneath, and creating an aged look. Often achieved by the use of wax finish.
