Re: Brass in a Still

    The worry about brass is not that it replaces copper, nor the zinc, but the lead that exists in some brass alloys to make them easier to machine or draw into

      The worry about brass is not that it replaces copper, nor the zinc,
      but the lead that exists in some brass alloys to make them easier to
      machine or draw into final shapes.

      That lead can be removed from the surface of the brass pieces by
      soaking them in a solution of 2 parts 5% vinegar and one part 3%
      hydrogen peroxide for a few minutes. If the solution turns blue
      green, mix up some fresh solution and repeat. The brass will turn
      golden yellow.

      I'd strongly recommend doing this to the tubes you will use, because
      the condenser IS directly in the path of consumption, and any lead
      that leaches out will end up in your final product.

      There is a lot of information on this subject to be found by
      searching the homebrew digest archives (www.hbd.org)

      Cheers,
