Hi Linda,

    There should be no real issues with using silver or gold as a support
    for paint, Both metals have been extensively used - usually in the
    form of gold or silver foil, to underlie both oil and acrylic
    paintings. Most of the Russian icon paintings used metal foils to
    give the paintings sparkle both as reflecting foils under the paint
    and as surface embellishments. Silver and gold foils were also used
    commonly in the painting of miniature portraits in the 17th and 18th
    centuries under egg tempera paint and gouache which are very similar
    to acrylic. The only real concern is whether the silver would
    oxidise or darken over time. This happened to some egg tempera
    paintings due to the sulphur in the egg part but this is unlikely to
    be an issue with most modern paints. If the silver is to be exposed
    at any point to give a shiny highlight, it will, of course, need a
    coat of lacquer to keep it from oxidising in the air. 

Best wishes,

Ian
