are jou sure this image shows mold? Have you taken a sample of the white residue (e.g. with some transparent scotch tape) and looked at it under light microscopy? Using lactophenol blue (cotton blue) as a stain will accentuate the structures of mold, so you can more easily differentiate between mold and other residues.
Could the white residue maybe be some substance crystallizing within your silk fibres?
If it really *is* mold, part of devising your conservation treatment should be to consider if:
- wetting the textile might promote further mold growth
- what effect using a detergent might have on possible new mold growth (most detergents leave residues on the fibre, thus the fibres will take up humidity more readily in future resulting in a slightly higher equilibrium moisture content of the fibre, i.e more humidity is available for the growth of conidia)
- what other ways of cleaning might be possible
For effects of treatments on mold development, please have a look at:
Mary-Lou E. Florian: "Fungal Facts - Solving fungal problems in heritage collections", Archetype Publications, London 2002., Esp. Box 4.3 p.36: "Summary of activators of conidia".

1. Here are two images from the textiles that were infested in the past from mould.
2. I would very much appreciate if anyone knows any articles or research on KIERLAON OLB KONZ as a detergent fro textiles (aprticularly wool I believe). Is the first time I have found some but since never used here I would like to know more on it before do some tests.
Many thanks

Konstantinos: You have looked at the white spots under the microscope? Can you scrap a few off and see if they dissolve in water? Have a pH? What kind of a box? Where was the box stored? Send us a photo? Mary

Subject: Mould infestation on excavated ancient costumes
Importance: High
Dear all
I found extensive mould infestation (white spots covering the whole robes including the linings) on costumes whihc are folded in layers and placed for years in the same box. I have nevere seen these costumes before as this is the first time I opened the box for survey of the textiles. The alarming incident needs direct attention. Except from surface cleaning, can anyone suggest imediate measurements and if possible materials that could help on this? Storage conditions are stable but the collection has been moving around for several years. Since excavation it is known to me of any treatment for possible mould attack on these pieces from previous owners/conservators.
The costumes are all silk with metal threads.
Thank you for your time and help
