Question

Identify the correct information in context to Etching technique of printmaking. A. Metal plates are etched with bitumen mixture. B. Copper plates are etched with adulterated spirit. C. Copper plates are etched with Ferric Chloride. D. Zinc plates are etched with a highly diluted solution of nitric acid. E. Zinc and Copper plates are etched with the benzol. Choose the correct answer from the options given below:

• A. A and B Only
• B. B and C Only
• C. C and D Only
• D. D and E Only

Hint:

Remember the common etchants used in printmaking: \[ \boxed{ \begin{aligned} \text{Copper Plate} &\rightarrow \text{Ferric Chloride}, \text{Zinc Plate} &\rightarrow \text{Dilute Nitric Acid}, \text{Bitumen} &\rightarrow \text{Acid-resistant Ground}, \text{Benzol} &\rightarrow \text{Cleaning Solvent}. \end{aligned} } \] Mnemonic: “Copper--Ferric, Zinc--Nitric.”

Answer 1

The Correct Option is C

Concept: Etching is an intaglio printmaking process in which acid bites into the exposed areas of a metal plate. Different metals require different etchants.

Step 1: Examine each statement. \[ \begin{aligned} A. &\ \text{Incorrect. Bitumen is used as an acid-resistant ground, not as the etchant.} B. &\ \text{Incorrect. Adulterated spirit is not used for etching copper plates.} C. &\ \text{Correct. Copper plates are commonly etched with ferric chloride.} D. &\ \text{Correct. Zinc plates are commonly etched with a dilute nitric acid solution.} E. &\ \text{Incorrect. Benzol is a solvent/cleaning agent, not an etchant.} \end{aligned} \]

Step 2: Identify the correct statements. The correct statements are \[ \boxed{C \text{ and } D} \] Hence, \[ \boxed{\text{(C)}} \]
