New pieces









The Jumping Rabbits, brooch
enameled copper, brass, nickle silver, nickle, wool, cast resin



According to my theme, I symbolized the celebration and the completion, and they are represented on my works. The donut-shape pieces are holding pomegranates seeds, cast resin, in the middle, so I want more focusing exploration of my feeling about this project.






















The Jumping Rabbits#2

enameled copper, sterling silver, nickle silver, cast resin


























The Jumping Rabbits #3

Die forming process

2/16/2011


frame #3





frame #1








1. using the frame #3

① 95D/ 4000psi -> breaks the piece





2. using #3
① 80D/ 1500 psi -> 1/8 ~ 1/4 inch
② 80D/ over 2000 psi -> breaks the piece






3. using #3 (the only piece I got ok from these five pieces, 2/16/2011)
① 80D/ 1200 psi
② 80D/ 1500 psi
③ 90D/ 1800 psi (little below 1/2 inch)



4. using the frame #1
① 80D/ 1200 psi -> higher than the result w/ frame #3
②80D/ 1500 psi
③80D/ over 2000 psi -> breaks the piece




5. using #1
① 80D/ 1200 psi
②80D/ 1800 psi .................broke this one ...


I used 24g copper, and they are too thin to be formed with over 2000psi pressure.
I might try 20 - 22g copper as well.

Pieces #2, #3, and #4 are used 22g copper, and as I thought they stood the pressure over 2000 psi, bur has be under 2100.
For the best result I would use 80D urethane pressured 2000 psi with frame #1.
With Frame #2, I would use 95D and 80D pressured 3000 psi.
When I use 24g copper (thinner than 22g), with frame #2,
I would use 80D/ 1600, and the second try will be 80D/ 2500 psi.
