Origin
Cultivated and gathered across Iran; cochineal and indigo also traded.
Properties
- Plant and animal sources
- Some require mordants
- Abrash is not proof of dye source
- Varying lightfastness
Preparation
Preparation depends on fibre and dye system; indigo uses a vat process while many other natural dyes use mordants.
Care & preservation
Limit light exposure; colour and abrash alone cannot identify dye source or date a textile.
General guidance only. For valuable or fragile pieces, consult a qualified conservator before cleaning or treatment.
The traditional palette
Iranian dyers have used madder root for reds, weld, vine leaves and other yellows, indigo for blues, walnut husk and oak galls for browns and blacks, pomegranate rind for yellow-browns and, more rarely, insect dyes such as cochineal and lac for crimsons. Greens and purples are usually produced by over-dyeing.
The synthetic turn and revival
Synthetic dyes spread in Iran from the late nineteenth century; early aniline dyes faded badly and were officially restricted for a time. Chrome dyes later became standard. From the late twentieth century, revival projects, notably in Fars and among Qashqai weavers, reintroduced plant dyeing for gabbeh and other rugs.
Claims and evidence
'Natural dyes' in a listing is a claim. Only laboratory analysis identifies dyes reliably; colour harmony, abrash and fading are not proof. A rug can also mix natural and synthetic dyes.
Practical questions
- Are natural dyes always better? They are valued, but quality depends on dyeing skill.
- Can one rug mix dye types? Yes.
What counts as a natural dye
Natural dyes are colourants taken from plants, insects or minerals rather than synthesised. In Iranian textiles the core palette comes from madder root (reds), indigo (blues), weld and other yellow plants, walnut husk and oak galls (browns and blacks), and pomegranate rind. Most need a mordant, usually alum, to bind to the wool.
Synthetic dyes arrived in Iran in the later nineteenth century; their misuse led to bans in some periods and a twentieth-century revival of natural dyeing in Fars and elsewhere. Today both are used, and many rugs mix them.
What you can and cannot tell by eye
Uneven colour bands across a field (abrash) appear when yarn was dyed in separate small batches — common with natural dyes but also produced deliberately with synthetic ones. Very even, saturated orange or purple is more often synthetic. None of these signs is reliable alone; only laboratory analysis (for example HPLC) identifies a dye.
- Abrash: a batch effect, not proof of natural dye.
- Colour at the tips versus the base of the pile: fading pattern can help, but not decide.
- Ask what dye and mordant were used, and whether the maker can show the dye house.
Why the photo stays empty
The natural-dyeing technique page shows a real dyers' row in an Iranian bazaar, but its record does not say whether those hanks were naturally dyed. A photograph cannot show what dye is in a yarn, so we have not illustrated this material page with a coloured rug and called it 'natural dye'.
