Lost Wax Casting: Carved Stone Ring (cont'd)

Here is the ring after I polished it with Tripoli compound.  There is excess Tripoli in the grooves of the ring which is why the cracks have a dark finish in these photos. It's a pretty nice effect but if I want to make it permanent I'll have to use some sort of chemical solution.

I put the ring into the ultrasonic to clean out the Tripoli and the ring was gleaming bright!
