I, among others, are ongoing and happy students of Jay Whaley, at
the Jewelry Studio, in the Crafts Center, at UCSD, in La Jolla, Ca.
Jay's suggestions are put into use every day, they are clear, and
easy. No need to make them complex. All that is necessary is to make
very certain that your coin is indeed Fine Silver 999, and unless
you plan to make bezel, you can add an alloy to bring it to Sterling
I am a fan of Argentium, but the Alloy that Jay gets for the Studio,
from Universal Refiners of S88 or SA88, I'm not sure, makes for a
very good looking Sterling, that is definitely tarnish resistant.
So basically, you do have a crucible to melt within, an ingot mold,
to pour within, and a Rolling Mill, that has grooves, within which
you can roll your ingot.
The rest is as Jay says, very easy, roll, anneal, and repeat until
you get the thinnest, longest form, Press the ends into the grooves,
to form a taper, and begin to pull through a plate, remembering to
anneal often. Within a reasonable time, you have your desired wire.
Sure beats opening a catalog, phoning in an order, and waiting for
delivery. In Jay's very first class, I see brand new students, leave
with a wearable piece of jewelry.
Believe what he says, I do.
A satisfied student, paying for the class.
