I am fairly new to geology and to rock hunting, fossil hunting, and Rock tumbling. That being said I have two double barrels and one single barrel running 24/7 for the last couple of months. Different batches of course. I am going to be working with calcite that I collected in the Anza Borrego State park next to the Salton Sea on our last geology trip. And I have read some of the threads where you need to check it every single day and start with a higher Grit like 220 that's what I'm thinking. I did get a large piece I have a big hand and it's about the size of my fist that must have fallen off of one of the trucks that were pulling it out of the mine back in the 40s and 50s because this calcite was used for the gun sights on the 29 bomber and others during WWII

Welcome to the forum from South Dakota! Heck, that calcite find sounds awesome! "When" you figure out Cloudinary, pics of that would be awesome to see!

Welcome from NY state! The Vikings supposedly used high grade calcite to locate the sun on overcast days for navigation on their ships.
