[Jewelry making - Article 01099] - [Orchid] Likely Toxicity from Patinas?

[Terri May]

========[ Invite a Friend - http://www.ganoksin.com/invite.htm  ]========

    Where would I look to find out about "contact" toxicity of patinas
    once they are fixed to the metals? 

    I'm interested in whether heat patinas on copper or bronze are
    possibly toxic (contact toxicity)through long-term wear (like on a
    bracelet). 

    I'd also like to find out if blackened brass (via the stuff used on
    gun barrels) might possibly be toxic (contact toxicity). 

    I would be treating the patinas with Renaissance Wax or Johnson's
    Paste Wax to protect the surface, but long term wear will obviously
    wear down through and expose the patina to skin contact.  (I'm more
    concerned here about the people wearing the items than the patina
    <smile>). 

Thanks for any help.
--Terri
