Textile Fragments with Irises · mid-17th century · Silk, metal wrapped thread; lampas · Iran
The Metropolitan Museum of Art, 09.50.1110a, b · CC0 · Museum record
One catalogued Iranian example whose museum medium line names this material; not a defining specimen.
Origin
Historically Gilan and Mazandaran sericulture; also imported.
Properties
- Very high tensile strength
- Fine gauge allows dense knotting
- Strong lustre
- Light-sensitive dyes
Preparation
Cocoons are reeled, degummed, thrown into thread, then dyed in small lots.
Care & preservation
Highly light-sensitive. Store flat, in the dark, interleaved with unbuffered tissue.
General guidance only. For valuable or fragile pieces, consult a qualified conservator before cleaning or treatment.
Filament, spun silk and sheen
Reeled silk combines long filaments from cocoons; spun silk uses shorter fibres. Degumming, twisting and finishing change handle and lustre. Silk is a protein fibre, but smoothness does not distinguish it reliably from regenerated cellulose marketed as “art silk”. Fibre identification should be separated from the identification of a carpet workshop or a weaving date.
Read the material by component
A silk-highlighted wool carpet is different from silk pile on cotton foundations, and both differ from a textile with silk warp and weft. Ask for a component-level declaration rather than “100% silk” without qualification. Historical Kashan silk carpets illustrate a documented museum category; they do not set current prices or authenticate a contemporary seller’s carpet.
Condition and identification without damage
Light exposure, handling and past chemical treatments can weaken silk. Look for splitting, powdering and tears near old folds. Some historical silks were weighted with compounds that alter their ageing, but damage alone does not identify weighting. Do not burn a thread, scrape a painted surface or use a hot-needle test. A conservator or fibre specialist can advise on minimally invasive examination.
Display and support
Minimise light exposure and support the whole textile, especially weakened areas. A fragile silk panel may need flat storage rather than rolling; a robust textile may be rolled on an appropriate support. Avoid a universal storage recipe. Silk rugs with unstable dyes or unknown repairs should not be subjected to stain-removal experiments; a blotch may involve the fibre, dye, finish or earlier treatment.
Practical questions
- Is “art silk” natural silk? Usually it is a trade term for other fibres; request the exact composition.
- Can silk be authenticated from shine in a photo? No.
| Feature | What it can tell you | What it cannot establish |

| Strong sheen | Surface appearance | Silk fibre identification |
| Silk highlights | Local use of silk if documented | All-silk construction |
| Splitting at folds | Structural weakness | Date or weighting diagnosis |
