Pure silk has a feel, a sound and a shine that imitations struggle to match. Here are a few simple ways to tell — though the surest is always to buy from someone you trust.
The feel and the warmth
Real silk is cool when you first touch it and warms quickly in your hand; it feels soft yet substantial. Synthetics tend to stay cool and slippery, or feel oddly plasticky.
The shine
Genuine silk gives a gentle, shifting sheen that changes colour as the light moves — a quiet, deep lustre. A harsh, mirror-like, unchanging shine often signals polyester.
The rustle
Rub real silk gently and you may hear a soft ‘scroop’ — a faint, crisp rustle. Many synthetics are silent.
The burn test (for a single thread)
If you can spare a thread from an inner seam, real silk burns slowly, smells like burnt hair, and leaves a brittle, crushable black ash. Synthetic melts into a hard bead and smells of plastic. Do this carefully, with a single thread only, away from anything flammable.
The surest test of all
Buy from a weaver or seller who tells you the truth about their silk and zari. At Khinkhwab we’re always clear about what’s pure and what isn’t. Explore our handwoven Banarasi silk sarees.
Frequently asked questions
How can I tell if a saree is pure silk?
Check the feel (cool then warm, soft but substantial), the shifting sheen, the soft rustle, and — with a single spare thread — the burn test: silk smells of burnt hair and leaves crushable ash.
Is the burn test safe to do at home?
Only with a single thread from an inner seam, away from anything flammable. If in doubt, rely on feel, sheen and a trusted seller instead.
