Final answer:
The Indus Valley Civilization, also known as the Harappan Civilization, used technologies like bronze and copper and made fired bricks; the 'Dancing Girl' bronze statue exemplifies their metalworking. They were also advanced in urban planning and engaged in far-reaching trade that facilitated cultural and technological exchanges.
Step-by-step explanation:
The Harappans of the Indus Valley Civilization employed various technologies and craft materials, which included bronze, copper, and fired bricks. The use of bronze, indicative of their cultural and technological exchange with Mesopotamia, was apparent in their artistry, most famously in the 'Dancing Girl' statue created using the lost-wax method. The Harappans were skilled metallurgists and craftsmen, as well as adept urban planners. Their urban society was marked by orderly streets and advanced drainage systems, made possible by the mass production of durable fired bricks. Both Harappa and Mohenjo-Daro, two of their most well-known cities, showcased this level of planning.
The civilization's trade networks, extending as far as Mesopotamia, not only facilitated the exchange of goods like tin and copper but also cultural and technological ideas. This network probably aided the introduction and development of bronze technology within the civilization. The Harappan artisans created objects from various materials and were particularly known for their detailed work in bronze and terracotta. They manufactured jewelry, figurines, and pottery, exemplifying their craftsmanship. Harappan technology and societal structure have left an enduring legacy, influencing later Indian civilizations.
