[log in to unmask]" type="cite">Hi,I have used graphite bought from the hardware shop, sold to loosen up locks, but only the micro fine will work. I found that the harder and stiffer my brush or tool, the darker the tonal effect, ie, soft sable = light tone, stiff taklon or hogs hair bristle brush = darker tone, paper stub = darker again.Yes super for illustrating bones, my students did an amazing job with skulls and so quick compared to pencils !I first came across it in the GNSI handbook many years ago, what a revelation?Such brilliant artists !
