During the Mature Indus (Harappan) period, Chanhu-daro functioned as a major center of specialized craft production, especially stone-bead (lapidary) manufacture integrated into the urban fabric—an early example of concentrated workshop-based industry.
Workshop evidence from Chanhu-daro documents the full lapidary production sequence—cutting, preforming, perforating/drilling, and polishing—showing standardized technical practices and organized work routines rather than ad hoc household crafting.
Indus lapidary traditions at Chanhu-daro included the production of carnelian ornaments (including valued bead types) that required careful thermal and finishing control as part of the manufacturing workflow, underscoring high technical skill in workshop contexts.
Chanhu-daro is closely associated with etched carnelian beads (white-painted designs fixed by heating), a hallmark Harappan ornament type whose distribution beyond South Asia reflects the wider circulation of Indus luxury goods and technical know-how.
Archaeological evidence from Chanhu-daro includes stone drills and drilling debris alongside numerous unfinished beads, supporting interpretations of intensive, workshop-based bead production rather than primarily finished-goods consumption.
Surface-study mapping and artifact clustering indicate that bead-making indicators (debitage, rough-outs, drill-blanks, and associated tools) concentrated in particular sectors, implying zoned activity areas and managed craft space within the settlement.
Chanhu-daro’s craft profile also included shell working, with evidence for producing items such as shell bangles and related objects—another specialized workshop tradition within Indus craft economies.
Finds from Chanhu-daro include evidence for sophisticated metalworking; for example, a tool identified as a snarling iron (used in repoussé/metal forming) has been discussed as expanding understanding of Harappan technical capabilities.
Indus craft production (including goods associated with Chanhu-daro) formed part of broader internal and external trade, with material culture linkages and comparable artifacts supporting models of integrated distribution networks across the Indus realm and beyond.
By the late Mature Harappan era, Chanhu-daro’s specialized crafts (lapidary work among them) represent the persistence of urban workshop production even as parts of the Indus world approached systemic transformation.
Around the end of the Mature Indus period (commonly placed near 1900 BCE), major urban institutions and several specialized urban crafts diminished or transformed, marking a watershed for workshop-centered production systems like those documented at Chanhu-daro.
Chanhu-daro entered modern archaeological literature after investigation by N. G. Majumdar (noted in accounts as occurring in 1931), laying groundwork for later interpretations of its craft-specialized character.
A large excavation campaign took place in the 1935–1936 season under Ernest J. H. Mackay, producing foundational evidence for interpreting Chanhu-daro as a manufacturing settlement with intensive craft production.
An illustrated popular article (July 1937) by Dorothy Mackay summarized major discoveries from the 1935–36 work, helping disseminate evidence for Chanhu-daro’s manufacturing character (beads, seals/weights, and other craft products) to a wider readership.
A three-day field visit and study (March 1984) by G. M. Sher and Massimo Vidale recorded surface distributions of craft-production indicators, reinforcing earlier interpretations of specialized activity areas at the site.
Archaeological work resumed in the mid-2010s under the French Archaeological Mission of the Indus Basin (CNRS/partners), aiming to refine understanding of the site’s early centuries and the extent/organization of its workshop complexes.
