Analytical laboratories
 
Hi

Can anyone provide recommendations for labs that perform AMS dating on antique textiles, and others that will perform identification of dyes used on antique textiles ? I am interested in wool samples, in particular.

For dyes, Paul Mushak had been the go-to source for decades, but since he passed away last February his sample turnaround times have increased dramatically.

I have used the AMS lab at the university in Waikato, in New Zealand, for archaeological samples - but not for textiles.

US based labs would be preferable, but are not a requirement.

I know we had a long discussion on radiocarbon dating about six years ago - my head hurt by the end. I'm looking for current resources.

Regards

Hello Chuck,

I understand that Beta Analytic, in Miami, might be the place to go.

Good luck!

Hi Lloyd,

Thanks, I have seen their website and may inquire further. There's a lab in Arizona as well. I'm more that a little surprised that - aside from your learned self - there's been no response from the TT crowd. I guess Jim and Kurt don't troll as much as they used to.

I have a chuval I'd like to get tested - I think probably 1850-1875, not really great age, but I'd rather get as much info as possible. The technology is out there, so why not.

Thanks
Chuck

Hi Chuck,

I for one would be very interested in a report when you've done something.

Hi Chuck

Jürg Rageth’s “Turkmen Carpets, A New Perspective” refers to Georges Bonani from ETH Zurich for the large number of rugs AMS/c14 dated in the book. ETH must have a lot of experience specifically on the turkmen rugs now :)

Hi Martin,

Thank you, I will investigate the Zurich lab's capabilities. For the piece I wrote about last year, I ended up using the lab at the University of Arizona, and was quite happy with their work.

Chuck I am curious on how you in generel look at c14 dating of rugs these days? And I am of course also curious on the specific test of your Chuval, would love to see a picture and see the c14 results

Jürg Rageth in his new book doesn't seem to take any reservations (expect of course of the variations in the peeks). Overall I personally thinks the C14 datings in his book looks realistic to me, though I have seen others expressing the oppersite on various FB forums.

All the best

Martin, Rich,

I'm getting some material prepared for a mini-Salon on Turkmen work, and trying to decide whether to address this there or here. I'll show you the results shortly, either way.

Regards
Chuck

Hi all,

OK, the torba with the radiocarbon analysis is in the new mini Salon:
