Here’s my question…and I thought you would know…
A good friend of ours (very knowledegable antiques dealer and French
& Indian War expert) has an early 1700’s -ish mold for original
trade silver… it is brass and about 1/8’ thick. He would love for
me to pour some silver pieces…but here’s my question…
This is a valuable piece and I do not want to hurt it. Can I safely
cast molten silver in a brass mold? It has 5 little hearts and
circles with a flat back piece and pouring spouts for each. So it
looks like a mold.! They don’t seem to fit tight enough so there
will be some air space and I imagine that this would allow the air
to escape. What do you think about this? Have people used cut brass
molds with molten silver? I am concerned b/c the melting point of
silver is higher than that of brass? But then again the brass is at
room temp and there isn’t a huge difference in melting point. The
brass has some kind of blackening…probably oxidized over the
years. The impressions are pretty small and about 2mm deep. What
keeps the silver from adhering to the mold? Do I need to worry about
a mold release of some sort?
My husband and our friend are very excited by the possibility of
trade silver from an authentic mold. But I do not want to ruin it.
Any ideas? I thought if anyone would know…you might. Thanks…for
any ideas or suggestions that you might have!
