The village of Kieu Ky in Hanoi's Gia Lam district, Vietnam, is a national cultural heritage site. There, people have been inlaying gold and silver for more than 400 years. This profession requires meticolous precision and hardwork. In fact, to make just a raw Litmus leaf, the artisan goes through 20 different handmade stages. The job requires sophisticated techniques and flawless manual skills. Around 1,400 hammer blows are needed to obtain one golden Litmus leaf. Artisans use gold and silver to produce unique artifacts such as Buddha statues, horizontal paintings, and couplets. This profession hasn't always been preserved. Inlaying gold and silver was very popular before 1945, but with the two wars against the French and the US, this job almost ceased to exist. Luckily today, associations, villagers and artisans are keeping it alive. At least 50 families specialise in gold lamination in Kieu Ky. Nguyen Anh Chung says: "The Kieu Ky Gilded Association includes 20 artisans and 100 members that maintain and develop the craft village. This profession is very meticulous, patient, and difficult".
