How to tell real pure silk from artificial polyester or viscose silk. Complete testing guide including the burn test, wedding ring test, touch warmth, and Central Silk Board verification.
Pure silk fibers refract light at diverse angles because of their natural triangular prism structure, producing an iridescent glow that shifts as the drape moves.
Synthetic art silk possesses a single, high-gloss plastic sheen that reflects light harshly and uniformly. Under studio flash or sunlight, art silk photographs with a glassy glare.
The smell test is foolproof because silk is pure keratin protein, identical to human hair and sheep wool.
If the thread smells like chemical fumes or burnt paper, it is either polyester (plastic) or viscose (wood cellulose).
Reputable saree boutiques will gladly trim a 1-inch thread from the unstitched blouse allowance to let you test before high-value bridal purchases.
Artificial silks tend to bunch, catch, and exhibit static cling against metal or smooth surfaces.
Another simple tactile check is rubbing the fabric briskly between your palms for 10 seconds: pure natural silk generates instant thermal warmth; artificial fibers stay cold or produce static electricity.
Beware of generic labels that say '100% Silk Touch' or 'Pure Silk Look' without the official Silk Mark butterfly logo.
At Mumbai Bazar, every pure silk saree carries an authenticated Silk Mark tag, providing complete certification and peace of mind.
Frequently Asked Questions
Is 'art silk' legal to sell as silk in India?
Consumer protection rules mandate that sellers clearly disclose synthetic content. Selling polyester or art silk as pure silk without disclosure violates the Consumer Protection Act, 2019.
Why do pure silk sarees cost significantly more than art silk?
Pure silk requires silkworm rearing (sericulture), hand-reeling of raw filaments, and manual pit loom weaving that takes 10 to 40 days per drape. Art silk is mass-produced in powerloom factories in hours.
Can art silk sarees be dry cleaned?
Yes, but solvent dry cleaning often dissolves synthetic finishes and glues used in art silk zari, resulting in loss of luster and stiffness after 2–3 washes.
