Silverpoint is a drawing technique using a silver rod or wire to make marks on a specially prepared surface. It was used extensively during the Renaissance by artists such as Leonardo da Vinci, Albrecht Dürer, and Raphael. It was valued for its precision and the fineness of the lines it could produce, making it ideal for detailed studies and preparatory sketches. Over time, the silver oxidizes and the lines darken to a warm brown or sepia tone, giving the drawing a unique character that changes with age. This method was popular during the Renaissance and earlier periods. It allows for very fine lines and detailed work, making it suitable for intricate drawings. Unlike graphite, silverpoint lines cannot be erased, requiring the artist to be precise and deliberate with their marks. Lines produced in silverpoint drawings are generally lighter and less intense than those made with other mediums, lending a subtle, delicate quality to the artwork. 

Note: due to the reflective nature of the silver it is difficult to photograph the drawing.
