Tin is the fourth valuable metal followed by platinum, gold, and silver. When the daughter of Emperor Qianlong in 1772 was married, he commissioned a set of tin carving as the dowry in Laiwu and it was known by the world for winning the International Silver Award at the Panama International Exposition in 1915. Tin vases keep flowers fresher for longer periods of time. Vase designs have become valued as a collectable today.
