Bidri Metalwork
Zinc and silver, blackened by the soil of a single fort. A craft that cannot be moved.
The Tradition
A craft that depends on a single patch of earth
Bidri is a metalwork tradition that began in the 14th century in the fort town of Bidar, in what is now north-eastern Karnataka. It is one of the rarest crafts in the world for a strange reason: it cannot be practised anywhere else. The final, defining step of Bidri — the step that turns dull grey zinc into the deep, permanent black that is the craft's signature — requires soil from the grounds of Bidar Fort itself. Something in that particular soil, which scientists have not fully explained, reacts with the zinc alloy in a way that no other soil on earth will.
This means every Bidri artisan alive today works with a material tie to a single specific place. The craft is, in the most literal sense, of the ground.
The Technique
How Bidri hardware is made
A Bidri piece begins as a sand-cast blank made from a zinc alloy (roughly 16 parts zinc to 1 part copper). While the metal is still soft, the craftsman carves a design into its surface with a chisel. Into these carved channels he hammers pure silver wire or silver sheet, cut and shaped freehand. The silver inlay sits just above the surface of the zinc and is then filed and polished flush.
Then comes the step that gives Bidri its name. The piece is coated in a paste of mud drawn from Bidar Fort, ammonium chloride, and water, and left in the sun. Within minutes, the zinc surface turns matte black — a deep, permanent, soft-edged black — while the silver inlay remains untouched. The contrast is what Bidri is famous for: bright silver on a black field that looks, depending on the light, almost like velvet.
Each Bidri button CETHORA uses is cast, chiselled, inlaid, and blackened by hand, one at a time. There is no batch mould. Each button is slightly different from the next in the way a handwritten letter is different from a typed one.
The Artisan
Anand Reddy
Anand Reddy is the fourth generation of his family to work in Bidri. His great-grandfather began the workshop. His grandfather taught his father. His father taught him. Every element of The Threshold Coat's hardware — buttons, toggles, closure plates — is cast and finished in his workshop, one coat's worth at a time.
It takes roughly 246 hours to complete the hardware and wool-silk weaving behind a single Threshold Coat. Of those, sixty hours are Anand Reddy's work alone. The rest belongs to the weavers he supplies.
Why Bidri
The weight of permanence
CETHORA chose Bidri for one reason: it will outlive everything else on the coat. Silk fibres soften and fade over a lifetime. Wool felts. Leather cracks. But a Bidri button, made correctly, will look exactly the same in a century as it does the day the coat ships. It is one of the few materials in fashion that actually keeps the promise of permanence.
That is quiet luxury. A coat hardware that quietly refuses to age.

Questions
About Bidri Metalwork
What is Bidri metalwork?
Bidri is a 14th-century Indian metalwork craft from Bidar, Karnataka, in which silver is inlaid into a cast zinc-alloy base and the base is then blackened using soil from Bidar Fort. The contrast of bright silver against permanent black is the craft's signature.
Why does Bidri only come from Bidar?
The blackening step of Bidri requires a paste made from soil drawn from the grounds of Bidar Fort. Something in this specific soil reacts with the zinc alloy to produce a deep, permanent black that no other soil on earth produces. This ties the craft physically to the town.
Who makes the Bidri hardware on CETHORA's Threshold Coat?
All Bidri hardware on The Threshold Coat is made by Anand Reddy, a fourth-generation Bidri craftsman from Bidar. Approximately sixty hours of his personal work goes into each coat's buttons, toggles, and closure plates.
