Metallurgical heritage of India : Preservation and rejuvenation

India is reputed for its metallurgical heritage since the 4 th century BC. CSIR-NML uncovered some
of the secrets of the archaeological monuments of India such as the corrosion resistance of Delhi
iron pillar and Konark Temple and the structural integrity of the Nilchakra of the Puri temple
using some modern tools and techniques. Although these monuments have stood the test of time,
traditional artisan practices may become extinct without science and technology interventions to
make them competitive in the market. CSIR-NML has been working with clusters of metalworking
artisans towards implementation of total technology packages that improve the quality and economy
of production of traditional items without compromising on the traditional practices and heritage.
The important works on ‘Bidri wares’, casting of brass and bell metals, rural blacksmithy are
highlighted.
