Anotations

Scope note:

Drawings made by using an implement comprising thin, sharpened rods of silver, usually in a holder, on a support of paper, parchment, or wood treated with a prepared wash or gesso. Ivory may also be used as a support. The silver lines oxidize quickly, making the drawing more distinct, but still delicate and fine.
