Never heard of cooking rocks. Looks to be a smart idea though to test how they will hold up.

Sorry I have not kept up with your posts. So much going on with STEEM.

Well, good luck with the rock test. Hope it works well. I went to Basic Training out that way at Fort Leonard Wood, Missouri so I know it gets cold! That was my first boot camp, then guess it was not enough so went to Parris Island, South Carolina a year later (warmer there)! 🤣🤣🤣

Have a great week. Blessings and groovy vibes to you and your loved ones.
