A 500-Year-Old Silk Tradition, Woven into a Bag

★★★★★ 4,000+ Verified 5-Star Reviews

Five centuries ago, under the southern Chinese sun, artisans began dyeing silk not with chemicals — but with the earth itself.

What emerged was Xiang Yun Sha (香云纱) silk, a textile so exquisite, it was once reserved for nobility; now recognised nationally as China’s Intangible Cultural Heritage (2008).

Today, Tang Heritage revives this endangered art form, transforming it into heirloom pieces for the modern bag collector.

Washed 3 Times, Boiled 9 Times, Dried 18 Times — By Hand

The Process

Each length of Xiang Yun Sha silk undergoes a ritual spanning 30 to 40 days, guided not by machines... but by sunlight, patience, and human hands.

‎

The process demands not only physical endurance but years of training — three to four years just to become proficient in the dyeing and sun-curing craft. This mastery marks a true artisan’s status, as few achieve the precision required to perfect every layer.

  • Washed 3 Times: Each wash purifies the silk, removing what’s superficial to reveal what’s pure.
  • Boiled 9 Times: Boiled in wild yam extract, the silk absorbs nature’s tannins, deepening into its signature bronze tone.
  • Dried 18 Times: Laid by hand on open grass fields, the fabric is sun-dried daily, absorbing the warmth, wind, and scent of the earth.


Every stage of this process is a labor-intensive meditation in patience, essentially a month-long dialogue between human craft and natural rhythm.

How It's Made—Full Timeline

A Silk That Obeys Only the Weather, and Science

The Science Behind

Xiang Yun Sha silk cannot be mass-produced, simply because its very creation depends on climate, chemistry, and chance.

Too much rain, and the oxidation halts. Too little, and the sheen dulls.

Its beauty is born from a fragile equilibrium between humidity, sunlight, and the iron-rich composition of river mud used in its dyeing.

The mud’s high Fe(II) content reacts naturally with the plant tannins, a centuries-old chemistry that bonds color permanently without synthetics.

The result is a silk that darkens under sunlight and matures like bronze, a living textile that evolves with age.

So rare, even nature and science must agree to create it.

40 Hours to Craft, By Hand

The Artisans

Once the silk is perfected, it is entrusted to our atelier artisans — each bag requiring over 40 hours of meticulous handwork.

Not because it’s easy, but because it must be perfect.

Because a fabric this scarce deserves craftsmanship that does its 500-year-old tradition justice.

Every cut, stitch, and seam is performed with precision worthy of the silk’s rarity. We do not rush this process, we honor it.

Each artisan approaches the bag as both a responsibility and an homage; preserving the integrity of Xiang Yun Sha through skill, discipline, and reverence.

Their hands work endlessly so yours can carry something eternal.

The Heart

The Art of Sustainable Preservation

Xiang Yun Sha embodies sustainability not as a trend, but as a philosophy. An unbroken dialogue between humanity and the earth.

  • Sun-Cured, Earth-Dyed

    Each piece of silk is dyed and cured in the open air, laid on grass fields, bathed in river mud, and dried by sunlight.

    This natural alchemy replaces synthetic dyes with the chemistry of the elements themselves, leaving behind no waste and no toxins.

  • Dyed With Earth's Essence

    Its signature bronze-black hue comes from the roots of the wild yam, an indigenous plant rich in tannins.

    The dye is entirely biodegradable — harmless to skin, waterways, and soil — a textile that gives back to nature as it takes form.

A Promise That Outlasts Time

The Promise

We don’t cut quality. We cut middleman.

Luxury bags typically retail for $2,200–$5,000 in traditional retail boutiques — not because they cost that much to produce, but because of the 5–6 layers of markups between the artisan and the customer.

Tang Heritage removes all that.

No retail landlords.
No wholesalers.
No middlemen.

Just highly-skilled master artisans, premium cowhide, and rare Xiang Yun Sha silk delivered straight to you.

This is how we offer world-class craftsmanship at a fraction of what traditional luxury brands would charge.

A Promise That Outlasts Time

The Commitment

At Tang Heritage, we do not chase trends. We seek to preserve them.

Each Cloud Silk Peony piece honors the artisans who kept their Xiang Yun Sha silk craft alive, long after the world forgot their names.

What you hold is not simply a creation, but a 500-year-old dialogue between past and present.  A story of patience, purpose, and artistry; reborn for the modern collector.

How It's Made: 30-40 Days of Making

Step 1

Day 1

Extracting Nature’s Dye

The process begins with freshly harvested Shu Liang roots, ground and pressed to release a natural juice rich in tannins.The extract must be used the same day, before oxygen dulls its power.

Step 2

Days 2 to 3

The First Immersion

Silk is soaked in the freshly prepared plant extract, then air-dried indoors for two days. Each strand absorbs its first bronze hue, a fragile foundation that sets the tone for everything that follows

Step 3

Days 4 to 10

Sun, Patience, and Repetition

For the next seven days, artisans brush dye onto the silk and lay it beneath the southern sun; repeating this cycle five to six times. Each exposure deepens the tone and binds the tannins into the silk’s core.

Step 4

Days 11 to 25

Deep Dye Fixation

Across the next fifteen days, the dyeing and sun-drying ritual continues. Each piece is handled, lifted, and laid down more than a dozen times. By now, the silk has absorbed every shade of patience.

Step 5

Days 26 to 30

The Mud Alchemy

From the Pearl River Delta, artisans collect iron-rich mud that reacts naturally with the tannins to create Xiang Yun Sha’s bronze-black glow. The silk rests under open skies as science and nature fuse; sunlight oxidizing the minerals into permanent beauty.

Step 6

Days 31 to 35

Washing, Sun-Curing, and Refinement

Once the mud dries, it is rinsed away and the coating repeated several times. Each cycle polishes the surface, softens the fibers, and enhances the lustre. After thirty-five days, the silk breathes, fragrant with the memory of soil and sunlight.

Step 7

Beyond The 35 Days

The Artisan’s Mastery

It takes three to four years of apprenticeship before an artisan can master this process. Timing, weather, and instinct decide success.
