Our research on
traditional iron and steel smelting began when we visited Channarayanadurga in
Tumakuru District, Karnataka, many years ago, while retracing Buchanan’s Journey. It was a fascinating exploration locating
what could have been the very sites that Buchanan had visited. More significantly, however, it led to a
startling “discovery”: the environmental consequences of this activity that was
not just some small village activity but actually one that was carried out on
an industrial scale.
