Hi,I recently purchased some rugs on a local online auction. My experience has been with Navajo blankets and don't know much about rugs. I got a total of 8 rugs at the auction, five of which look to be possibly hand made. This is the largest at 47" x 76" not including the fringe. There is a 4" fringe on top and a 7" fringe across the bottom. I am trying to find out where it was made, how old is it, and is it worth getting appraised? The rugs were just listed as "area rugs". There was nothing else of any note at the auction in my opinion. The rugs all have different styles and to me it looked like a "collection. I look forward to any information or opinion you have. Thanks

Hi, Does anybody have an opinion on this rug. Would this be better described as a oriental rug or a Persian rug. If it is hand knotted, where would it have been made? Thanks.

Hi, I don't know much about rugs, but from what I've learned here I'd guess it's silk on silk from Turkey maybe 1980's...looks very similar to one I have. Tree of Life design.

Thank-you Fredgrower. What kind of value does your rug have? It looks similar in size.

Fredgrower, It looks like the fringe on the top of your rug is also longer than the bottom. Is this a characteristic of this type of rug?

I did the burn test on the fibers and I do believe it is silk on silk.

It is a Turkish Kayseri rug, the warp and weft are cotton, the pile is so called "Flosh Silk" - it looks like real silk but is not.

Thank-you KAD for the info. Is Flosh Silk manmade. Would it be considered a "lower end" carpet. How does it wear? Does it have another name. I tried looking it up but couldn't find it.

kansas1412,
I received your samples and tested them with the Biuret test for proteins as well as the burn and microscopic test. I received three different fibers. One white, one green, one red. The white fiber burned like cotton. It flared and didn't self extinguish and smelled of burning paper. The other 2 samples where too small to burn test. I ran the Biuret test twice. The first time with 10 percent NaOH to dissolve the fiber and 4 percent CuSO4 to react with any peptide in solution indicating a protein. ( Note: Silk and wool contain proteins, cotton and synthetic do not). The first test was negative. A positive test is where the light blue copper sulfate solution turns purple. I noted the fibers were still visible in the NaOH after 2 hours. I'm not sure the fibers dissolved. I increased the NaOH from 10 percent to 40 percent and put the new samples in a water bath at 160F for 24 hours. The red thread dissolved completely the green only partly dissolved. None of the samples turned a classic purple of a positive Biuret test but the green and red fibers reacted to different degrees. In the image labeled final the beaker on the left is unreacted CuSO4. The next beaker is a know wool. The first test tube is the red fiber. The right test tube is the green fiber. The pictures don't do the colors justice but the small beaker and the left test tube have a distinct purple hue where the right test tub is cobalt blue. I can't say with certainty but the red fiber may contains protein. The green fiber is inconclusive. Moving to microscopic both the green and red fibers show very fine floss similar to silk and does not indicate courser wool. All said I can't confirm but it is possible it contains silk

This test process still needs refinement. I haven't found any literature specific to testing rug fibers. I suspect that the dyes in the carpet may interfere with the classic color change of the Biuret test.
