The Correct Option is C
Solution and Explanation
Concept:
Glass manufacturing involves batch preparation, melting, refining, forming, and annealing. Sintering is mainly associated with ceramic powder processing.
Step 1: In glass manufacturing, raw materials are first melted to form molten glass. \[ \text{Batch} \rightarrow \text{Melting} \]
Step 2: The molten glass is refined to remove bubbles.
Step 3: The glass is then formed into products such as sheets, bottles, or fibers.
Step 4: Finally, the glass is annealed to remove internal stresses.
Step 5: Sintering is not a normal process in glass manufacturing. It is mainly used in ceramic processing where powder particles bond together below melting point. Therefore, the process absent in glass manufacturing is: \[ \boxed{\text{Sintering}} \]
