In a significant breakthrough for India’s traditional pottery sector, researchers at the National Institute of Technology (NIT) Rourkela have developed a patented green technology that dramatically reduces the time and environmental impact involved in producing black terracotta wares.

The new method, patented under Patent No. 572754 (Application No. 202531008090), cuts the firing duration from nearly 48 hours to less than 7 hours, while eliminating harmful emissions that typically affect artisans’ health. The innovation is expected to revive and modernise generations-old black pottery craft practiced across India and neighbouring regions.

The research team is led by Prof. Swadesh Kumar Pratihar, Professor of Ceramic Engineering, along with Shiv Kumar Verma, Senior Technical Assistant, an
