A city that never grew its thread

Scholars of the Banaras brocade state it flatly: silk yarn was never local to this city or its surrounding districts. The worm was never Banaras's trade. In the old centuries the hanks came down from Bengal, over the passes from Central Asia, and by sea and caravan from China; the state it sits in still produces only a fraction of what its looms consume — Uttar Pradesh reels roughly four hundred tonnes of silk a year against a consumption around three and a half thousand, with Varanasi the biggest eater of the difference. The arithmetic has been the same for three hundred years: nine-tenths of what this city weaves arrives as someone else's harvest. Banaras chose its half of the bargain long ago — not the growing of silk, but everything that happens to silk afterward.

Mysore mornings

Today the thread's longest road starts in the mulberry gardens of Karnataka — the Mysore and Ramanagara belt that reels roughly a third of India's raw silk, the largest share of any state. India's crop is overwhelmingly mulberry, around ninety-two percent, and its premium grade is bivoltine — finer, stronger filament from silkworm strains raised two generations a year. The other road comes from China: imported raw silk meets roughly fifteen to twenty percent of Indian demand, and many Varanasi weavers have told reporters plainly that they like its uniform filament under the fingers. A loom does not care about geography; it cares about evenness. The official price tables put raw silk around three thousand rupees and more per kilogram — which is why, before a single motif exists, a saree's worth is already lying in the yarn basket.

What katan means

Raw silk arrives stiff, gummed with the sericin the worm wrapped around its own filament. The city's first act is a bath: the hanks are boiled until the gum releases and the thread turns floss-soft — degumming, the moment silk becomes silk to the hand. Then the twist. Katan — the word on so many of our labels — is filament silk plied and twisted into a yarn with enough backbone to carry zari brocading: smooth, dense, durable, the ground of the classic Banarasi. The dyers take it next, working in open courtyards near the weaving quarters, hank after hank into colour. A standard saree warp carries some three and a half thousand silk ends, sized with tamarind-seed starch so they survive the loom's argument. Only then do the naqshaband's drawings and the punched cards enter — and the weaving, days to months of it, begins.

The lanes where yarn becomes money

The thread changes hands in the oldest lanes of the city — the Chowk quarter, where Kunj Gali alone holds more than two hundred shops and the trade clusters of Golghar and Rani Kuan have run for over two centuries. Here sit the gaddidars, the trading masters who advance yarn against finished sarees — the financing system a Banaras Notebook essay walks through on foot. It is an old machine with old frictions, and the Journal does not romanticise it: the weaver's share of a saree's price remains the thinnest slice of the arithmetic. Part of why we work the way we do — loom to baithak, weave and zari named plainly — is to shorten that road.

Why it matters to your saree

Because the thread is the saree. The reason a true katan Banarasi hangs with weight and returns light softly — the reason it survives a generation folded in muslin — is decided before the first pick is thrown: mulberry filament, properly degummed, honestly twisted, dyed in the city that has judged colour for centuries. When you ask us what a saree is made of, this essay is the long answer behind the short one.

Plain answers

What is katan silk?

Pure mulberry filament silk, plied and twisted into a strong, lustrous yarn — the classic ground thread of a Banarasi saree.

Where does Banarasi silk come from?

Not from Banaras. Historically Bengal, Central Asia and China; today mainly Karnataka's Mysore-region mulberry belt, with imported Chinese filament meeting part of the demand.

Does Varanasi produce its own silk?

No — Uttar Pradesh reels roughly 400 tonnes a year against some 3,500 tonnes consumed. Banaras has always been a weaving city that buys its yarn.

What is bivoltine silk?

India's premium mulberry grade — finer, stronger filament from silkworm strains raised two generations a year, centred on Karnataka.

What is degumming?

Boiling raw silk to dissolve the sericin gum, turning stiff raw filament soft and lustrous before dyeing and weaving.

Why is a real Banarasi expensive?

Costly twisted mulberry silk, metal zari, weeks of design work in graphs and punched cards, and days to months on a handloom — the price is the process.
