Zimmerman Silver Green gives the best silver reduction effects ever! This is a granular size (looks like a size 2 grind) so you can roll a bead in it or use it to pull stringers from. Can also be reduced for a shiny surface. My favorite way to use this is to mix it with Lauscha Transparent Copper Green or Mint Green for an iridescent stringer. COE 94-96. Each jar weighs 3.8 oz. Zimerman is no longer in production.
