What do you do with a whole bucket of egg shells? The Internet says to turn it into calcium for your garden (specifically tomatoes) and for your chickens as an oyster shell substitute. I bet I could even sprinkle some on Joe's lettuce!
I thought it would be a lot more work than it actually was.
First, I collected eggshells in an ice cream pail until I had plenty to work with. Some sources said it was important to bake the eggshells to kill any salmonella that might be on them, and I decided to try that method. So I baked the eggshells at 400° for 10 minutes. That's what all that golden brown coloring is on the shells in the bucket, baked egg whites.
Once they were baked, they sat in the ice cream pail for quite a while because I wasn't sure if I wanted to just crush them up or try to pulverize them. Eventually I decided to do the pulverizing method. We have a spice and nut grinder that I bought for G to grind his coffee beans. He doesn't use it much so I don't think he'll mind that I borrowed it. 😉
Pulverizing sounded messy and loud and hard on the equipment, which is why I was hesitant in the first place, but it wasn't too bad on all of the above. It didn't take long to grind up the entire batch of egg shells. The only downside of pulverizing was the very fine dust that flew up whenever I took the lid off after grinding, but that's easy enough to clean up.
And here's the end result!
