Overview: Traditional Korean paper, or hanji, was first made around 2,000 years ago. Made from paper mulberry bark, research suggests it is durable enough to last for over 8,000 years. It is especially coveted for its properties by those restoring cultural treasures. However, aging masters and a lack of successors has put the tradition's future into question. This time on Asia Insight, we meet 4th-generation hanji maker Jang Sung-woo, who resolutely adheres to traditional techniques, and is determined to pass on the wealth of his family's tradition to a new young apprentice -- and the next generation of papermakers.
