These blanks require finishing, which might include decorating (stamping, gluing, etc.); adding holes; filing, sanding, or hammering the edges; polishing and/or antiquing.

Raw Copper

• Raw (bare) copper is unplated, and is not as shiny as most plated finishes. However, it can be stamped, soldered, and giving the finish of your choice.
• To give an effortless high polish to bar copper items, tumble-polish them.
  Or, to give varying degrees of shine, from a matte finish to a mirror finish, use sandpaper or sanding sponges, and finish with an ULTRA polish pad.
• Raw copper items sometimes have a thin coat of oil. Warm water and detergent, or alcohol and a cotton ball, are all it takes to remove it.
• Prolonged contact with bare copper may discolor the skin of the wearer. Raw copper items will develop a natural patina over time unless sealed.
• To speed up the patina process, try applying an oxidizing solution such as Win-Ox (#86-343) or liver of sulfur.
