How It's Made S29 E12
Technological Corks, Zinc Gutters, Traditional Basque Ham, Chisteras

Processed cork is purified, ground and compressed into consistent bottle closures designed to reduce natural defects. Zinc sheet is roll-formed and joined into rain gutters; pork legs are trimmed, salted and slowly air-dried into traditional Basque ham; and long, curved chisteras used in pelota are woven by hand around shaped wooden frames.
