Correct Option
The correct option is Squeezing wax into noodle-like shapes.
Explanation
The terms "pichki" and "pharni" are integral to the traditional Dhokra metal casting technique, which is a variation of the lost-wax (cire perdue) process. This craft is predominantly practiced by tribal communities in regions such as Bastar (Chhattisgarh), Odisha, and West Bengal.
Detailed Analysis:
- Pichki: This tool functions as a press or extruder, similar in principle to a syringe or a vermicelli maker. It is typically a hollow bamboo or wooden cylinder with a perforated metal disc at the bottom.
- Function: Warm beeswax (blended with resin and nut oil) is placed inside the tube and pressed down with a wooden plunger. This action squeezes the wax out through the perforations, creating long, thin, noodle-like wax threads.
- Application: These fine wax threads are wound around a clay core to create the intricate surface details and structure of the final sculpture.
- Pharni: This tool is used subsequently to shape, flatten, or finish the wax threads on the model to ensure precision before the outer layer of clay is applied.
Key Takeaway: In the context of traditional bronze/bell-metal casting (Dhokra), the pichki is the tool used to extrude wax into fine wires for modeling the design.
