Guys,
I've got a small, what appears to be, a clay crucible that I've melted about 15 grams of .925 in (started out as a mercury dime and two silver rings). I've used propane in the past but tried MAPP and it actually does better. Hotter, I think. Well, I purchased one of those graphite molds on e-Bay which has been milled for 1/4 and 1/2 oz. Thought it'd be neat to make a little "bar" rather than the button I was getting from the crucible. So, last night I place this sliver in the new graphite mold to melt it. Well, I must've held that MAPP flame on that silver for 5 solid minutes and, although it did seem to soften, it would never Melt. Melts in about 30 seconds in the clay crucible. Anything I should know? I realize a furnace would do it and so would acetylene, but I don't have that. (plus, I don't plan to get into doing this - I just happened to have the scrap silver and a torch and wanted to try it)
Thanks
