NPR segment on running out of sand.

First it was the Buffalo and the Passenger Pigeon now it seems we are running out of sand. This according to NPR. I hope they don't blame glass blowers.

well, that article certainly oversimplifies things and didn't even bother mentioning fracking. Most of the silica the glass industry uses is really quite processed stuff.

What we're running out of is dinosaurs.

I use their Minispar feldspar and it's very nice. I was not aware of a pure silica being offered up and still prefer Short Mt for my own formulations. I believe Tom uses a lot of Oklahoma #2 or texas sands for batch. The point is for a sharp edged crystal with a very low iron content. I recall Kona Spar was mined there until the factory burned down.

Tom gets his sand from US silica. I know this because they reuse the pallets that have it painted on them. AND THEY DONT FIT A STANDARD PALLET JACK!! Grrrrr

Pallets are strange things. These days they seem design specific to the company at the beginning. My tractor forks have to be moved constantly to accommodate pallets and the pallet jack here rarely gets used anymore.

I suspect US Silica has a bunch of different mine locations, a whole bunch. It's strange how some shops spend an enormous amount of time trying to get rid of them, others charge for them. My beef is that every one seems to have one nail protruding from it that rips the bottom bag everytime.

When I was at Penland they used to go over to the feldspar plant and buy silica. It was a by-product and they practically gave it away. 120 pound bags!

Way back, when I lived in Santa Fe, selenium was an unwanted by product of Copper smelting and it was 4 dollars a lb in El Paseo del Norte. I bought large tins. I'm still running on that Selenium with about 10 lbs left.

we used to get 20KG buckets of Cerium as samples. Life was good and we had no clue.
