As part of the sixth phase of ongoing archaeological exploration, four weighing stones of different sizes, all spherical and black in colour, were excavated from Keeladi.
R. Sivanandam, Deputy Director of the Tamil Nadu State Department of Archaeology, says that these weighing stones were found near a furnace, along with iron, copper artifacts and glass slag, suggesting the possibility of trade activity.
The stones were of various sizes — weighing 300, 150, 18 and 8 grams. They ‘d all been made of basalt. Every stone has a flat base and a polished surface. The stones were excavated from June 20 through July 3.
Mr. Sivanandam said the stones were found near a furnace, with signs of activity in fire. Charcoal was found generally at all levels on which the stones were excavated.
“The glass slag was contained near the furnace, as well. This suggests that there may have been bead-making activities here at Keeladi. Before selling them, the weighing stones could have been used to weigh the beads, “Mr. Sivanandam said.
