Question

The lost wax process is used for ______________.

• A. Honey making
• B. Jaggery making
• C. Batik painting
• D. Metal casting

Hint:

Understanding the etymology of technical terms can often provide clues to their meaning. "Lost wax" directly implies that wax is used and then removed or 'lost' in the process, which strongly points towards a molding or casting technique.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The question asks for the application of the "lost wax process". This is a term from the field of art and manufacturing.
Step 2: Key Formula or Approach:
The solution requires knowledge of this specific technical process. The name itself gives a clue: a wax model is created and then "lost" (melted away) during the procedure.
Step 3: Detailed Explanation:
The lost-wax process (also known by its French name, \textit{cire perdue}) is a method of metal casting. The process involves several steps:
1. A sculpture or model is first made from wax.
2. This wax model is then covered with a clay or plaster mold.
3. The mold is heated, which hardens the mold and melts the wax, which is drained out. This leaves a hollow cavity inside the mold that is the exact shape of the original wax model.
4. Molten metal (such as bronze, brass, or gold) is then poured into the hollow mold.
5. Once the metal cools and solidifies, the outer mold is broken away to reveal the finished metal object.
This technique has been used for thousands of years to create intricate metal sculptures and jewelry. The famous "Dancing Girl" from Mohenjo-Daro is one of the earliest known examples of this process.
The other options are incorrect: Honey making involves bees, Jaggery making involves boiling sugarcane juice, and Batik painting is a method of wax-resist dyeing applied to cloth.
Step 4: Final Answer:
The lost wax process is used for metal casting. This corresponds to option (D).
