USING ENAMELS OF METAL CLAY

    Oh, and when I made my metal clay test strips I resented the cost, so I made them with a nice texture, a bit of Keum-boo gold, and hole at the top so I could wear them as mini-pendants of earrings! Now I've gotten over it and I'm glad I did them, but it hurt at the time. The texture helps to see how the enamels look over different depths.

    Yesterday I did the same on copper, but I cheaped out and did them on copper pennies!

    Boy you are right!! I hadn't thought about the fact that is does frost up again when refired....re-opening....golly, I'm sure that's right...you always are!!! That is a really good tip to do both sides at a time for that reason!! Geee Wiz I just love scientific insights!!!

    Hi Trish,

    I have found that the metal clay has to be fired a very long time if you want to avoid that golden color. Maybe the binder is not completely burned off yet and that's what's causing the golden color. I made one silver PMC piece, and when I applied flux it fired to a mustard color, but I kept re-firing it at 1550 degrees and the flux eventually turned clear. I was then able to finish enameling it and the colors looked normal. I can post photos if you want to see them, but the inside of the lid to my tree frog box is one example of PMC that I was able to enamel successfully. Anyway, you could probably save your pieces by re-firing at a high temperature.

    Great thoughts,
    My next problem is getting rid of the fine silver frost - even when I tumble it
    for a long length of time, the little nicks and crannies won't clean up - I use a glass brush, brass brush, tooth brush, and still it won't polish up..

    I will check out the tree frog colors - but I am always fearful of over firing as the enamel I apply is just a thin coat. But I will take all this into my brain and try the next project with everyone's suggestions.

    Mucho gracias
    Trish

    Thanks Ann! It's good to see you on the site. Trish, I wonder if a dental tool would work for burnishing your PMC crannies that won't polish up. Not the kind with the very sharp point, maybe the kind that's slightly flattened. I understand your fear of over firing; everybody has their own approach. I was not afraid of it because I knew the piece was ruined anyway if I didn't try something experimental.

    Great idea,
    never thought of burnishing.. Do you have any of these problems?
