I'm trying to get a sense of the makeup of "Jupiter Sand" in a Craigslist ad. It looks like my J82 Petrobond clone from Pyro Minerals. I haven't put a hand in it yet to see if it could be added to my heap. Every inquiry on the internet comes back as jewelers petrobond. Has anyone else heard of it?
The seller called it Jupiter sand, but it looked and felt like PetroBond. It was virgin sand, never used and the squeeze and break was nice and clean. Scored about 180 lbs for $50 and a 50 mile trip.
Yes, I was suprised that it lasted. Although I have only met one other caster here in Reno. My usual run is 400 miles round trip to Oakland.
