I have a friend who borrows my bench and advice from time to
time to make a piece of jewelry. He wants to make an engagement
ring and is rather set on using platinum. The problem is that I
have never worked in platinum (only gold and silver) and am
wondering what is involved and how much harder is it to work
with. I have suggested to him that it may be easier to make a
wax model and send it out to be cast. That way he would only
have to deal with setting the diamond and finishing the piece.
Does this sound appropriate? Or am I being chicken? What extra
materials and equipment would be involved if he wanted to
fabricate it (I have most of the usual gold/silver working
tools)? Is an acetylene and air torch hot enough to solder
Thanks for any advice.
