Who using Zircon heavy sand in their bags?

[JohnnyJohnson]

If there any real danger here you already wouldn't be using it in California since it has to do with guns bet on it.

How true ;D The sale/importation of Zircon sand would also be illegal here if were dangerous I can't think of any other place on earth that has such idiotic laws as does California.

Oh no, don't let the Californians know about it! Sergy, are you sure you are from Russia? You sound a lot like like someone from California. ;D
Sorry, I just couldn't resist. Great information Sergy. Always wondered about sand that dense.
