[Jewelry making - Article 01100] - [Orchid] PNP paper falls off during etching

[Suzanne David-Vojnich]

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

    I am etching silver using PNP paper and nitric acid. The solution is
    3 parts water to 1 part acid. 

    When I lift the silver out of the bath to check its progress the PNP
    paper falls off part of the silver, preventing me from replacing the
    silver back into the acid bath. Fortunately, this has not destroyed
    anything I am working on but I am afraid that at some point it will.
    Does anyone know how I can prevent this from happening? 

Thanks!
Suzanne
