Most silver used in Bali is mined in other parts of Indonesia. They start by weighing 100 grams of the refined silver, and add 5 grams of copper. The end product of this mixture is around 95% silver. The refined silver/copper mixture is heated until it is liquid. It's then poured into a steel "mold" to create silver bars. The bars are then hammered to smooth out all the bumps and unevenness, and remove some of the impurities which reside on the surface. From these silver bars will come the three essential bead-making ingredients? Every single Bali Silver Bead you can get your hands on is made using two or three of these "ingredients. They are flat silver pressed into long strips, very small silver balls of varying sizes and silver wire. After the beads have been completed, they'll be oxidized. The oxidation turns them completely black. They are then polished in a tumbler to get them nice and shiny.
