Those babies are hot,hot,hot..
Those look perfect. Out here in the Mojave Desert in Trona,Ca all the marbles laying on the surface have been exposed to hurricane-force sandstorms. So the marbles' surfaces have been ablated. To find bought-yesterday antique marbles I must dig. Unfortunately,during the 1940s hundreds of tons of bricks,cement sidewalks and the whatnot were dumped atop the old marbles. So I often have to dig up tons of detrious to reach the untouched layers that contain pristine marbles. When I'm able to post pics here you'll all be surprised at what I'm finding.
