Recently, two such scholars, Jack Haldane and Nest Rubio, have attempted to replicate the ancient dyeing Antique oriental rugs often display a characteristic that one never finds on rugs made after the invention of synthetic dyes. Antique oriental rugs frequently have abrash. Abrash is the name given to the hue or color change that can be observed when viewing older rugs from multiple angles. Abrash results from either inconsistent dyeing or the introduction of new wool before a given rug has been completed.

s such deep, rich colors. Recently, two such scholars, Jack Haldane and Nest Rubio, have attempted to replicate the ancient dyeing process they envisage it. These studies have focused on the ability of yarn to absorb the red color from the natural madder root.

Haldane and Rubio reasoned that the makers of antique oriental rugs did not want to waste valuable fuel to heat the water that was used to dye the wool for the rugs. They reasoned that the absorption or the madder dyes must have taken place over an extended period of time, and at temperatures about equal to those used for making yogurt. The reasoning of Haldane and Rubio showed an exc
