This was a fun commission: a jazz lover asked me to "bring Dizzy Gillespie back to life - in any way possible".
I came up with this simple idea which I (humbly) call a Markison Ceramophone; consists of a hand thrown (black mountain cone 10) ceramic base with a sgraffito technique portrait of Dizzy scratched through a thin layer of porcelain back to the darker clay body when leather dry, base then bisque fired at cone 6, then clear-glazed and final fired at cone 10, Bluetooth wireless speaker fitted into the scroll-sawn cone (concentric 1cm thick rings cut at 28 degree angles into 3/4" thick pine, then reassembled and glued up)/lathe finished using Cole jaws and then shellacked to capture mid and high tones (ceramic base acts as "woofer"), cone then fitted into the base; music beamed from cell phone or other device via Bluetooth from up to 30' away - nice full warm sound (customer happy, now wants Django Reinhardt, Louis Armstrong, Charlie Parker, Sarah Vaughan and John Coltrane ceramophones - but willing to wait a while):
More fun ahead.
Best regards, Bob
