Why must paper or wooden panels be coated with a specially prepared ground (such as bone ash or gesso) before drawing with a silverpoint stylus?

Silver metal is too soft to mark raw paper; an abrasive ground is required to shave off minute particles of silver from the stylus. Raw paper reacts chemically with silver, causing immediate bleaching of the drawn lines. Silverpoint ink is liquid and requires a waterproof sealant to prevent paper fiber swelling. The ground acts as a magnetic base that pulls silver atoms into alignment.

Correct Answer:

Silver metal is too soft to mark raw paper; an abrasive ground is required to shave off minute particles of silver from the stylus.
