EXAMINER REASONING

Examiners test your ability to differentiate bronze sculpture from stone sculpture, identify the technical process (lost wax), and correlate bronzes with dynastic patronage (Chola, Pallava, Vijayanagara). UPSC often asks about Nataraja as a philosophical synthesis and about GI-tagged bronzes (Swamimalai, Dhokra).

Core Concept

Indian bronze sculpture reached its zenith under the Chola dynasty (9th–13th c. CE). Using the lost wax (cire perdue) technique, artisans created iconic images of Hindu deities—most famously the dancing Shiva Nataraja. Bronzes were primarily processional icons (utsava-murtis) carried in temple festivals, distinct from stone moola-vigrahas. The tradition continues today in Swamimalai (Tamil Nadu) and in tribal Dhokra casting.

Lost Wax (Cire Perdue) Process

1. A wax model is sculpted with all details.
2. It is coated with layered clay (investment).
3. The assembly is heated; wax melts and runs out ("lost").
4. Molten bronze (panchaloha – five-metal alloy) is poured into the cavity.
5. After cooling, the clay shell is broken to reveal the cast.
6. Final chasing, polishing, and patination complete the piece.
