Hi, Noel, This is hardly my area of expertise, but couldn't you caste
gold mesh using another kind of mesh? Then you could use whatever
alloy worked best. Maybe what you want to do is too fine for casting,
but I'm sure the extremely experienced casters among us would know
what is possible...
I have one of those gold mesh coffee filters and always think of how
much fun it would be to incorporate that stuff into jewelry. But I
suspect that the minimum order on such stuff might be really high.
Never mind that you couldn't call your pieces hand made!
