That pile of dirt from the new park build is perfect for tempering sand

I mean, they've been digging up ground for a playground a few blocks over, and there's just mountains of this sandy clay mix sitting around. We grabbed a few buckets on a whim, idk, maybe it's just me but it blends way better with our existing molding sand than the stuff we order. Last week we did a big iron pour for some machine parts, and the molds held shape like a dream, no cracking at all. It saved us from having to wait on a delivery, and honestly, it's free if you ask nice. I think a lot of local construction spots might have similar material if you look. Just make sure to sieve it first to get rid of rocks and junk. Give it a shot if you're in a pinch.

Heard construction clay works great for casting sand!

Always figured it was junk but Brian's right, it works way better than sand.
