Question

Sequentially arrange the process of manufacture of glass bottles used for food packaging: A. Surface treatment B. Raw material C. Mixing and melting D. Annealing E. Forming

• A. C, B, E, D, A
• B. B, C, E, A, D
• C. B, C, E, D, A
• D. B, E, C, D, A

Hint:

Understanding the sequence helps ensure that no critical steps are missed, which can affect the quality and safety of the glass bottles.

Answer 1

The Correct Option is C

Step 1: Concept
The process of manufacturing glass bottles for food packaging involves several steps that ensure the quality and safety of the final product.

Step 2: Meaning
The correct sequence of these steps is crucial to understand the production flow from raw materials to finished products, ensuring each step contributes effectively to the overall quality.

Step 3: Analysis
1. Raw Material (B): The process starts with selecting and preparing the raw materials, typically sand, soda ash, and limestone. 2. Mixing and Melting (C): After preparation, these raw materials are mixed and melted in a furnace at extremely high temperatures to form a homogeneous glass melt. 3. Forming (E): The molten glass is then shaped into the desired bottle shape using various techniques like blow-molding or press-blow molding. 4. Annealing (D): To relieve internal stresses, the formed bottles are annealed in an oven at high temperatures to ensure they do not break easily when cooled. 5. Surface Treatment (A): Finally, the bottles undergo surface treatment processes such as polishing and cleaning to improve their appearance and hygiene. The given sequence C) B, C, E, D, A matches this logical order of steps in glass bottle manufacturing for food packaging.

Step 4: Conclusion
The correct sequence is confirmed by following the logical progression from raw materials through each step until the final product is ready. Final Answer: (C)
