pardon the bad cell phone pic...this was my first venture into lost wax casting.

the ring is made of sterling silver.  it's rather bulky, and kind of dangerous (think brass knuckles), but it's pretty fun and a great conversation piece.

it's quite the process:
you start by making a model of your piece in wax, then attaching thinner wax rods called sprues.  the sprues later work to direct the melted metal down into what you're casting.  you have to be really attentive to detail when creating your model, because any bump, dent, or imperfection will be apparent in the final product.

after completing your model, the sprues are attached to a rubber dome that screws onto the end of a metal flask.  this flask is filled with a plaster-like substance called investment, which surrounds your wax model inside.

the last step is the most exciting.  the flask is placed in a kiln, and the wax model inside melts, leaving behind a negative mold of your design.  finally, you melt down your metal with a high temperature torch, and the flask is placed in a centrifuge.  the centrifuge spins rapidly, forcing the melted metal into the mold.

then, you retrieve your metal piece, clean it up and saw off the sprues (which are left behnd in metal form), and polish.

it was TOUGH!   Wink

ooh, very cool.

If I can't be my own, I'd feel better dead.

You know, my first lost wax was 11 ounces of sterling. A flower with all the petals filed to a point. It was pretty dangerous. I actually cut myself and a few others. Excellent job!
