- This paper discusses the preliminary data of iron smelting site found in the ancient iron smelting site of Tummu Ching, Kakching, Manipur. Excavation at Tumu Ching (lat. 24° 28' 38" N., long. 93° 57' 28" E.) a small hillock at a height of 776 m. above sea-level, near Kakching ~ 70 km. from Imphal, the capital city of Manipur has revealed plenty of iron slag in an area of ~ 0.5 km2. Baked sediments adhered to a broken piece of a slag has been dated by TL dating. The equivalent dose of the quartz extracted yield (3.37 ± 0.01) Gy. This corresponds to an age of (1600±100) years; the period when king Khamlangba ruled the valley from 300 to 500 CE.
