A reiteration of a bit from an entry made some years ago:
My dreams are bound together with waxed sail thread, glue stick and cello tape.
The faint image above is a test I worked with silverpoint last night. I’d have done more but my makeshift silverpoint stylus was very poor indeed, involving a length of jeweler’s silver wire taped to a chopstick. A graphite-holder is what I need, or similar. Anyway, it’s another age-old technique, which involves using a soft metal (gold, silver, copper, lead) to write and/or draw on a specially-treated ground. It was originally perpetrated on vellum (the real kind– animal skin) prior to the arrival of paper on the scene in Europe. The older the image gets, the more patina the metal takes on, enriching the tones.
