-mən/ (id)/ 1 Have you ever broken your favorite cup and thrown it 修復できません。 In away? Broken pottery cannot usually be repaired. Japan, however, there is a traditional technique that allows broken pottery to continue to be used. It is called kintsugi. 金継ぎ 2 Kintsugi is said to have been developed by Hon'ami Koetsu, a craftsman and artist of the Edo period. When a tea bowl cracked during firing, Koetsu fixed the pieces together with lacquer and applied gold to the join. Repaired by this kintsugi technique, the tea bowl held 10 water without leaking. 3 Kintsugi does not try to hide repair work. The gold joins stand out, adding new beauty to the repaired pottery. One of the tea bowls that Koetsu repaired by 雪峰せっぽう kintsugi is called Seppo, "Snow Ridge." Koetsu compared 15 the white glaze on the bowl to a snowy mountain and the gold joins to streams of melted snow. 4 Kintsugi combines two features of the Japanese spirit. One is mottainai, the valuing of things we use; and the other is the appreciation of beauty in everyday things. As 20 an expression of the Japanese spirit, kintsugi is attracting wider attention not only at home but also overseas. way 13. *stand out 9. join の意味は?
