Three summers of pouring in Phoenix taught me to check the sand temp before anything else
Back in 2019 I was running the afternoon shift at a small shop near the airport. We had a rush order for manhole covers and I figured the sand was fine because it felt okay on my gloves. First three molds came out spongy, looked like a cheese grater on the bottom. Foreman walks over, touches the sand with his bare hand, and says 'that's 140 degrees, you just wasted 80 bucks of iron.' Now I keep a cheap infrared thermometer on a lanyard and check every bucket before I ram it. Has anyone else had green sand act up when the ambient temp pushes past 105?

Did your gloves make the sand feel cooler than it really was?

Wait, is this about my beach trip where the gloves were actually just oven mitts I forgot to take off?
