Whoo boy. Good times.

But on plus side I get to sit in a chair and jam out to old school rock. So things could be worse.

I'd rather do this than cleaning, at least I feel like there is a goal. With cleaning it can be more abstract, because the place is pretty clean right now.

It's actually pretty easy to do that. Water helps, use a graduated cylinder. Or a tray or something.

sieve testing is so rote. Do y'all have a automatic rotating tapper or are you doing it old school and just shaking the stack a bunch?

We do it with sand sieves. I'm collecting size 40, which is 425 micrometer. Everything else is trash.

Shaking by hand. They said they used to have a shaker, but it ended up somewhere else in the country

Why are you doing that? I've done it for fun. In a lake, because the sand was about one-third Garnet, one-third Feldspar and one third whatever...

Well I mean yeah, that's what I'm doing. But the sand is completely random particle sizes. I think this is old sand that had previously been sorted to get a different size. So there is no rhyme or reason to the mix

So how does this work? Two sieves, one to filter out anything bigger and one for anything smaller?

More or less. I have 3 different sieve sizes. Middle sieve is the one I actually want the sand from.

Ha yeah. Not as bad as it was my last go around in an oil lab though. Frac tech has made some progress since 2015.
