This video was taken after two times in step one. The rock was mainly white when found. I was skeptical about positive results, but I am loving this rock.
My uneducated guess is leaning towards chert.... possible agate. Any Thoughts ?
People commonly call chert mixed with chalcedony "jaspagates", but I'm not sure what it really is from a scientific perspective.
You got a good one there! Jasp-agate, agatized chert nodule call it what you wish. It’s a combination of crypto and micro crystalline quartz with iron and iron oxide features or contamination, whatever the proper term is. Main thing is that little guy shouldn’t need much tumbling to really shine, it looks great after two course sessions so I’d move it on to stage 2. Otherwise you could start tumbling off the mustard yellow, which I understand is a form of iron/iron oxide. Yup, It’ll definitely glow when you put a flash light to it as it’s mostly chalcedony beneath the oxide colors. I find them with red coloring also and sometimes in really cool red and yellow combinations. Nice find there buddy!

Awesome. Thanks for all the information and suggestion to move. I have it in a bath waiting for other rocks that are ready for stage 2.

You mentioned that it was white when you found it so you were skeptical at first. That’s why I indiscriminately collect so much rock and run it through the rebel 17. Often I have no clue what’s underneath the white or yellow covering, which most of the rock here in central Texas is covered with. Some shapes and features can give away what’s underneath, but not always. So the only way to uncover them is to tumble, break them with a hammer, or saw them open. The ones that aren’t as impressive, which is the vast majority, get tossed into the yard.

You are absolutely 100% correct. Yes, there have been several rocks that I put into stage 1, then they unfortunately become part of my rock driveway. I have even rock-hounded, came home and do not understand why I put some of the rocks in my bucket. They were then sent to driveway duty. The skeptical part of the white rock was my fear that the white was just powder and would mess up the other rocks and the rock would turn out terrible. However, as you wrote, we do not know what is underneath the outside layer.

The white stuff on the outside only adds to the slurry, I have found, so you’re fine there. I used to get irritated by how much rock I would collect before realizing it’s a numbers game until I get better at identifying. I’m getting better now, but still collect way more than I can reasonably process. The kid has the same problem lol.

ThomasT: It always has amazed my mind that there are about 7.5 gallons in one cubic foot... I suppose due to an optical mental illusion from drinking thousands of gallons of milk...
