I. Basic Collection RecordCollection Title: Tang Silver Open Bangle with Horizontal Incised GroovesPeriod: Tang Dynasty (7th–10th centuries)Material: Forged pure silverFunction: Wrist ornament for noble women in antiquity, dual-purpose intact artifact for daily wear and burial intermentII. Form & Design AestheticsThis bangle adopts the classic open curled-tip style typical of Tang silver bracelets. It was forged and bent integrally from a single sheet of silver without splicing or welded filler. The band widens at the midsection and tapers gently toward both terminals, whose ends are tightly rolled inward into small cylindrical curls — a signature finishing technique of Tang silver bangles that enables adjustable fitting while preventing sharp edges from scratching the skin.Three parallel horizontal grooves are evenly chiseled onto the exterior surface with consistent depth and uniform spacing, embodying the restrained minimalist decorative style prevalent in the High Tang period. The interior wall remains plain and unadorned, retaining the smooth, delicate metallic texture left by forging. Its overall curve conforms naturally to the contour of a human wrist. Light and soft in silhouette, the piece rejects overcrowded elaborate ornamentation, relying on simple linear carvings to highlight the muted, mellow luster of raw silver, aligning with the elegant, understated aesthetic favored by Tang aristocrats.Gold and silver wares were precious ornaments exclusive to imperial courts and prominent clans during the Tang Dynasty. Silver bangles served both daily adornment and burial grave goods as markers of social status, standing as core physical evidence for the gold-silver craft industry and women’s costume culture of the Tang era.III. Silver Material & Tang Gold-Silver Forging and Chiseling CraftsmanshipCharacteristics of Aged Silver PatinaThe entire piece preserves intact natural burial soil infiltration and silver oxide rust patina. Its surface is covered with interwoven layers of grey-black, blue and brown natural aged crust, with oxidation penetrating gradually from the exterior into the silver core in soft, gradual gradients. No modern chemical acid washing or artificial dyed fake patina is present.The forged silver core remains dense and compact, free from extensive corrosion perforation, decay or fracture. Its metallic texture stays solid without severe pulverization after a millennium of burial, with the original silver glow concealed beneath thick, authentic ancient patina that exudes profound archaic charm.Ancient Forging and Chiseling Techniques of Tang Gold and Silver WareThe artifact retains complete traces of all handmade production procedures practiced in Tang gold and silver workshops:Forged forming: A single silver sheet was repeatedly cold-hammered and stretched to achieve uniform band thickness with seamless curved transitions, devoid of harsh angular creases from modern stamping.Groove chiseling: The three horizontal lines were flat-chiseled by hand. Fine reciprocating blade scratches are visible at the bottom of each groove, with subtle natural variations in depth unique to handwork, distinguishing it from uniform machine-carved lines.Curled-tip finishing: The cylindrical rolled terminals were formed by folding a single layer of silver sheet inward and compacting tightly with seamless joints, the standard closing method for Tang jewelry.Interior polishing: The inner band was repeatedly abraded with fine sandstone for a smooth, soft finish, marked by faint random grinding traces characteristic of ancient manual polishing.Forging and chiseling techniques reached full maturity in the High Tang. Plain bangles with simple horizontal grooves were mass-produced and widely circulated, serving as a representative category of Central Plains gold-silver jewelry shaped by cultural exchange along the Silk Road.IV. Condition ReportFully intact with no structural damage. There are no penetrating fractures, corrosion perforations on the band, chipped broken curled terminals or later welded repairs. The original open curve, rolled tips and three exterior horizontal grooves all remain in their unaltered Tang production state, without post-era grinding, reshaping or recarved decoration.Natural oxidation patina and burial soil encrustation cover the whole artifact completely. Ancient rust layers inside chiseled grooves and curled crevices are distinct and organic. All diagnostic markers including forged texture, hand-chiseling traces and thousand-year aged metallic patina are fully preserved and clearly distinguishable.No evidence of restoration, chemical cleaning or reshaping exists. This intact Tang silver jewelry is graded Excellent, the highest preservation tier for museum collections.
