Dear all, I am a student in conservation/restoration of textiles and I have a question regarding historical weavings. I hope you can help my by posting my question in the forum.
I am currently working on a fragment of a medieval fabric. It is a lampas-weave and is made of silk. The binding-warp shows an unusual coating. Microchemical tests for the evidence of wax or starch were negative. The REM-EDX spectrum shows the presence of Calcium, Silicium, Aluminium and Sulfur. Uncommon is also, that the binding-warp has no, or only a very weak twist. I could only find new-aged methods to strenghten warp-threads, but I could not find any argument for the coating of only a single warp-system in medieval times (probably animal glue?). Has anybody observed a similar phenomenon or has an idea, with what kind of substance the threads have been treated? Thank you very much, best wishes, Elisabeth ****** Unsubscribe by sending a message to [email protected] Archives through August 2016 at http://cool.conservation-us.org/byform/mailing-lists/cdl/ Archives from September 2016 onward at https://www.mail-archive.com/[email protected]/
