Dear All Thank you very much for your answers, advices and opinions. The lab here is newly established and many obvious materials are still missing, i.e. stereomicroscopes are only available at the moment and SEM or XRF is not available yet for fibres analysis. Yes, I meant Dehypon (and not Dehyphon as I wrote by mistake), and I read about its recent results on the environment. Though this is the only detergent available here basically. IMS and Acetone are also available in quantities here, thus included on the test. I am not experienced on enzyme treatments and considering the the pressure for the opening of the museum, I would prefer not to do follow this path. The rug has stains caught from earth/floor during its life mainly along with some dark black stains at the reverse lower margins. If other type of dirt is attached on it (mainly its reverse) it is not obvious. Water was an obvious solvent except that the yellow-gold of the rug was heavily bleeding. Then IMS and acetone were also tested with the hope that they might remove some dirt out from the rug. This did not happen in this case. It was then that I observed the stiffness caused to the rug mainly by the water but also from IMS/acetone. Wet cleaning such a large object alone it would be a challenge anyhow and if I can I would prefer to avoid it. > Date: Wed, 30 Jul 2008 10:12:28 +0100 > From: j.hackett@xxxxxxxxx > Subject: Dehypon? > To: TEXCONS@xxxxxxxxxxxxxxxxxx > > Mary: Perhaps Konstaninos meant to type Dehypon?
