nice pieces Keith - and thanks to Sue for some information about which I knew rather little. I have a personal mental description of these Harris pieces - and in my mind (perhaps wrongly) think of their surface decoration as looking rather like a sort of 'vermiculite' patterning. I have pieces from the 'Studio' range in white, red, and that rather iridescent black - as far as I know I'm certainly missing the blue ish sort of violet they did. And of course, each colour was produced in several different shapes.
