Patina The desirable change in appearance of leather due to normal use and time, affecting its color, texture and luster.
Sauvage A two-tone or marbled effect created by applying dyes or pigments to create highs and lows in coloration.
Oil-protected During 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 Up Leather 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-protected Leather that has been nished with wax for a smooth feel and burnished luster. Often, the wax will contribute to an aged, crackled look.
Crackle The nish 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.
