and here is his site on how he does it...

he just contracts time on prometals machine to do his sculptures and sell them ! and they are steel!

it works by gluing together metal powder, then heating it up vaporizing the glue and sintering the metal powder together, leaving 60% dense metal parts and then you dip it in bronze if its the steel and I guess for the gold you dip it in gold, I guess this is the thing that is their big intellectual property, so I think in the end you'd have solid gold

what about something like this with pearls...
