Lothali copper is unusually pure, lacking the arsenic typically used by coppersmiths across the rest of the Indus valley. The city imported ingots from probable sources in the Arabian peninsula. Workers mixed tin with copper for the manufacture of celts, arrowheads, fishhooks, chisels, bangles, rings, drills and spearheads, although weapon manufacturing was minor. They also employed advanced metallurgy in following the cire perdue technique of casting, and used more than one-piece moulds for casting birds and animals.[23] They also invented new tools such as curved saws and twisted drills unknown to other civilizations at the time.[24]
Lothal was one of the most important centres of production for shell-working, owing to the abundance of chank shell of high quality found in the Gulf of Kutch and near the Kathiawar coast[23] Gamesmen, beads, unguent vessels, chank shells, ladles and inlays were made for export and local consumption. Components of stringed musical instruments like the plectrum and the bridge were made of shell.[25] An ivory workshop was operated under strict official supervision, and the domestication of elephants has been suggested. An ivory seal, and sawn pieces for boxes, combs, rods, inlays and ear-studs were found during excavations.[25] Lothal produced a large quantity of gold ornaments—the most attractive item being microbeads of gold in five strands in necklaces, unique for being less than 0.25 millimetres (0.010 inches) in diameter. Cylindrical, globular and jasper beads of gold with edges at right angles resemble modern pendants used by women in Gujarat in plaits of hair. A large disc with holes recovered from a sacrificial altar is compared to the rukma worn by Vedic priests. Studs, cogwheel and heart-shaped ornaments of fainence and steatite were popular in Lothal. A ring of thin copper wire turned into double spirals resembles the gold-wire rings used by modern Hindus for weddings.[26]
