Some anthropologist friends requested early people pens with some sculptural relief. I posted my first run at 2 dimensional early people here:
http://www.penturners.org/forum/f13/early-people-virage;-including-handmade-paper-147730/
I figured that Art Clay Copper metal clay would serve the purpose.
Steps:
Figures initially tooled (chased and repoused, working front and back sides) into copper foil under high magnification.
"Master" tooled copper relief image then used to create a silicone mold for reproduction in copper metal clay.
Art Clay Copper metal clay rolled out to the thickness of 2 playing cards using an olive-oiled 1" diameter PVC pipe on an olive-oiled silicone sheet.
Silicone figures mold then pressed onto the copper clay.
Figured clay sheets air dried for a week (heat guns are avoided because they disturb the clay binder and compromise kiln firing).
Figured copper clay sheets kiln fired at 1800 degrees x 30 minutes, then quickly quenched in water to minimize firescale/oxidation.
Sheets then pickled in crock-pot-heated Sparex to remove the remaining firescale.
Sheets then washed well, and patina'ed with liver of sulfur/baking soda rub/thorough rinse.
Sheets buffed on a wheel with jewelers rouge, cut into strips, then rolled into spirals.
Brass pen tubes covered with handmade/hand marbled paper (please see my previous posts about paper making and marbling).
Paper/figure clad tubes then cast tube-in at 50psi with Douglas and Sturgess Clear Casting resin with copper flakes plus some mica powder to add a little "dust of time".
Turned and finished as usual.
My next little adventure will flesh out the early people in fine silver clay (they will go forth and multiply).
Happy Saturday to all - Bob
