Mixed activities here this evening. First up was a couple of tubes of this white mineral.
Then two more tubes with this lovely red earth laden with mica.
This afternoon I dug out silver wire from my chainmaking days. For weeks I've been thinking that my 0.5 mm Pentel mechanical pencil might make a good holder for silverpoint. 0.51 mm converts to 24 gauge in wire size. At the top of my pile of wire I found ten feet of 24 gauge fine silver! I clipped a piece, smoothed one end, and popped it in to work perfectly with my Pentel!
I'll probably want various gauges but this is a good start. Some tempera artists rough in their painting with silverpoint.
Here's a bit of silverpoint on gesso.
Wrapping up the evening was an attempt to finish one of the new Realgesso boards. I have an email into Realgesso for guidelines but in the meantime I used Koo Schadler's recommendations on the True Gesso site. I found that using the rougher grits seemed to be overkill, creating deep scratches that then took time to remove. Unless I hear different from Realgesso, on the next board I will begin with 320 grit, then 400, and finally 600. Perhaps different grit sizes and techniques are appropriate with boards from different suppliers, as well as when I make my own gesso boards.
