Hi frenchtoast - I'm also curious about it - sounds amazing in theory, as I gather the organic binder magically melts away in the firing process and you are left with pretty much pure silver. Drawback - yes - I think as lovemiki and alliemia have reported - it can look rather rough and ready - and I believe it also shrinks - so if making rings, this has to be taken into account. Can imagine though that it would suit very sculptural/organic/chunky designs best.....will keep an eye on this very interesting thread as it would be great to get some more opinions on people who have worked with it! (I have seen some items on Etsy that have been made from it - seems to suit brooches/pendants mostly etc...and of course it is mega-pricey, so no room for mistakes!....
