To ensure color consistency, all wool is dyed onsite using the age-old pot dyeing technique. Our dye masters submerge, simmer and spin the wool with the highest quality dyes to reach the optimal color saturation. In keeping with our commitment to minimal environmental impact, the dyes applied are the metal-free Nylosan/Optilan brand. These organic dyes, as offered by Clariant, are solid nonvolatile materials, and emit no off-gases. Offering a standard pallet of over 1200 colors, Tamarian rugs use a consistent formula to ensure the wool dyed years ago matches the wool that is dyed today.
