: : : : Some contributors have mentioned that very old Turkmen, and perhaps other tribals, have a special feel to them, as well as distinguishable physical characteristics of the fibers that are visible in the microscope. I wonder whether the same characteristics distinguish the 'old' from the 'new' in rugs from other areas that have a known continuum of production, such as Anatolia? If so, what is the time boundary between the old and the new, and what are the causes of the difference? Is it the aging process, or is it changes in the materials or techniques used?

: : : I have heard that older rugs are actually physically heavier in weight. Detlef Maltzahn confirmed this when he told me fake Caucasian rugs hitting the market are lighter by approx. 4 kg on the average than an old piece. Why this is so? Not sure but obviously materials in addition to encrusted dirt and dust may have something to do with it.
: : Herr Maltzahn makes an interesting observation as pointed out by Tom Cole. The very old Ersari main carpet that I recently acquired is only a small 7 x7 ft, yet it is heavier than a late 19th c Ersari maincarpet that is somewhat bigger and in better condition. Has anyone else had this experience? Regards, Marvin

I never thought about that; back to the physical chemistry books! Regards, Marvin
