Just found out how much a bad sand mix can cost a shop

I was reading an old trade journal from 2019 and saw a case study from a foundry in Youngstown. They tracked a single week of scrapped castings and found 40% were due to green sand that was off spec, mostly from wrong moisture. That's a huge number of parts just going back into the melt. It made me check our own moisture tests way more often. Has your floor ever had a run of bad sand that caused a major scrap pile?

We switched to daily moisture checks and our scrap rate dropped fast.

How much of a drop did you see? That's a great result... we've been fighting with scrap from humidity for ages.
