Question

Melting to adhere the rosin particles on the metal plate is done by carefully placing the plate -

• A. On a hot plate heater
• B. In running water
• C. In a soap solution
• D. Over the paper pulp cast

Hint:

The hot plate melts rosin.

Answer 1

The Correct Option is A

In the aquatint process, the rosin particles are adhered to the surface of the metal plate by carefully heating it on a hot plate heater. This causes the rosin to melt slightly and stick to the plate, creating a resist pattern that protects certain areas during acid etching.

• Heating process: Carefully heat the plate to melt the rosin slightly.
• Function of rosin: Creates a resist pattern to control acid etching.
• Importance of even heating: Proper and uniform heating is crucial to avoid over-melting and ensure consistent tonal effects.
• Outcome: Produces controlled tonal variations during the etching process.
