Yes: quartz, actually. However I have been advised that this will not be necessary; the flame will stir it plenty.HopeDream|1322965074|3073726 said:
Yes, of course. The white gold requires only about 500F higher temps than the alloy I've been using thus far.HopeDream|1322965074|3073726 said:Do you have the capacity to safely maintain the high levels of heat necessary?
I'm not sure why I'd do either of these things... no, the plan is to not.HopeDream|1322965074|3073726 said:Are you going to test it for purity before you cast the ring? (possibly not necesary) Are you going pour it into casting grain before using it? (I'm not sure if this is necessary or not)
My chosen alloy contains no zinc. The next lowest boiling point would be that of the copper, which won't boil unless I exceed my target temperature by almost double - an extra 2000F, well hotter than my torch. I don't think fumes are of any concern.HopeDream|1322965074|3073726 said:
The alloy I chose is a composition thats sold commercially and has at least 100 years of heritage based on the books I've read. I can't imagine that I'll have any trouble based on the composition itself. Of course, if I somehow screw up the alloying process that'd be another matter... but I'm an optimist.HopeDream|1322965074|3073726 said:If your homemade alloy turns out to be brittle, the prongs could crack or snap during the diamond setting process instead of bending nicely like they should - I'm sure you don't want that.
I wonder if you could trade your boullion metals to a jeweller in exchange for the casting grain of your choice? It would stil be using the value of your inheritance, but a lot less messy and heat-intensive.
Stuller X1 is supposed to be nice http://www.stuller.com/pages/1236, and there are a lot of other different casting alloys out there- including palladium white gold (Which I know you prefer).
Getting the grain would be no problem if I wanted it... but I don't want it. If my alloy doesn't work I'll do what it takes to make it work... and if that doesn't work only then will I buy some.
Thanks!HopeDream|1322965074|3073726 said:I'm sorry I ask tough questions - I really want you to succeed.
You're definitely getting much closer to your final cast - the most recent ring looks great!
