I thought I would share my second attempt to polish rocks using the new MT-4. I have to admit that after AO 1200, I documented in my notes that these were the worst looking rocks to ever come out of AO1200 to date. Then I ran them in the polish. I like all rocks so this is all of them. Some I like more. Others are red-headed stepchild looking. Overall Group photo: The Lavic group: The Colorado River group: The Amethystine group: The Oddball group: The Ore Car Clear Agate group: The Ugly Ore Car Embedded junk group: Thank you for taking a look.

Lookin' good, Bill. I think some of the problem is in the rocks you're tumbling, and some is in the first stage. There are a lot of cracks and spalls in those rocks. Some might have been possible to remove by running them longer in the first stage. Others look like they run throughout the rock and would never come out. Sometimes I use a chisel to break the rocks with cracks going all the way through them. Sometimes I throw them out. The Lavic doesn't have those problems and they look the best to me.

I really like the Colorado river group. Really nice color and shine on that set. I see a lot of potential in that material.

For overall group I like the Colorado river group. The large stone in the oddball group is interesting. Looks like you are getting a pretty good shine with the MT-4.

Yep the Colarado Group takes it home, I do agree. Good job.

Thank you for all the comments. And I appreciate the constructive feedback Rob.
All of this was intentional. My material is poor (most of it gathered 6 months before I had a tumbler, or even knew what kinds of material to bring home. I deliberately moved most of them to Stage 2, faced with a decision of taking them as they were or grinding them to pebbles. I knew before posting that 90% of the rocks would not even pass to Stage 2 for most RTH regulars; thrown out.
My next batch will finish this coming week, and the rocks look a lot like this; charity cases I chose to polished.

I was looking at some of the purple rocks, and I am not sure what I am seeing inside some of them. Is this a moss or detritus inside it maybe? I realize the probably no one will circle back to see this post. But if someone does, could you let me know what you think this might be inside? It is inside a bunch of them actually. Thank you.

Look like dendritic formations to me.

Thank you both! Dendrites! I knew I had read this somewhere. I Google searched like crazy before asking. Time to read up on this now.

So far, this is your best batch. It's amazing what adding a true polish step will do. Rob's advice is sound. While you can't necessarily change what you collected, I'd also recommend going longer in the first stage.
