I'm interested in bent plywood techniques.
ZenziWerken uses an intriguing technique to craft this bowl. 6mm birch plywood is cut (a CNC router was used here). Then the cut-out was rinsed with water and microwaved at 600W for 1 minute. The bowl is then shaped in a form (another bowl in this case) with lead weights and clamps. The bowl was allowed to dry and harden. Finally, some wood glue was applied at the tops of the spiral arms.
