I am back in Seattle from my New York-Pittsburgh trip. This little saki cup* made from 100% tin is a souvenir that I bought back. *I bought it in a Japanese book store in New York. For some reason I just feel attracted to metal items that’s a 100% pure element (gold and silver coins fall in that category!). And I know there are controversies around tin : the big tin mines in Indonesia have an appalling safety record, and there is a mine in Democratic Republic of Congo controlled by a renegade militia.
