[Jewelry making - Article 00252] - [Orchid] Raku glaze on PMC3 Firing Temperature

[Jeanne M. Bellone]

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

    I have used Silver PMC3 to make some end caps.  I have fired them
    all ready and they are ready to be used as is; but I would really
    like to fire them again using a Raku glaze which is mainly used for
    ceramics.  There are no instructions as to firing temperature that
    came with the glaze.  Can someone tell me what temperature should I
    fire the silver again with the glaze on it.  I don't want to go to
    high and melt the silver. 

    According to Tim McGreights book on Precious Metal Clay, he says that
    firing the PMC3 again with a ceramic glaze can be done; but there
    were no temperature there either. I have already tried 1450 degrees
    F. Supposedly when the glaze is hot enough it will look wet and
    glossy.  At that point, I am suppose to put it in a can of
    combustible material such as dried leaves, paper shavings, etc. and
    let it smolder; but I can't seem to get it to the point where it has
    the wet glossy look. Can someone guide me as to proper temperature
    to use in my kiln that will not melt my silver end caps.  This is
    very new to me.  

Thanks so much for any assistance!
