No sub-titles Mr connrock, sorry. this is not as thick as it was. Having a hard time getting the slurry thick enough to both tumble some with out clanking. Plastic beads looking better all the time. It needs to be buffered, PH too high. Messy. But makes a wicked cheap starter slurry other than mess and PH. You can hear the obsidian rattle by just stirring them around. Not so much when thicker, but it sure seems like bringing action would be hindered at high thickness.

What caught my eye right away wasn't ya'lls thick "lom"(Southern for "lime") slurry but rather that there aren't many smaller pieces of obsidian in the load? Is not using small pieces part of this experiment? What grit stage is this? I'm not sure what the PH has to do with all of this? I noticed that you're using that "P" word a lot lately too! LOL Shams,shame,shame!!! LOL Better watch out or captbob will have pigs flyin around here too! LOL connrock

LOL Shams,shame,shame!!! LOL Better watch out or captbob will have pigs flyin around here too! LOL connrock I thought about talking and decided it safer to say as little as possible as fast as possible. And was trying to speak proper, and failed LOL. Never ran obsidian w/hardly any smalls in past 2 months of experiments. Not sure why. It is improper practice. no grit, just watching and adjusting the slurry, I did not know if the slurry would get thin, instead it slowly got thicker. testing to see if it would remove the polish on some of the obsidians too. Oh, the PH, it is high. It would burn a ladies hands. not as strong as portland cement, but strong enough to effect your skin. there are different limes, calcium carbonate is much more mild. The lime in the video has very low quartz particle content. Some lime chemicals like calcium carbonate can have millions of fossil diatoms and was marketed as tripoli, diatoms being silica. captbob is going to take pot shots regardless, Preparation H close by. So far, floating plastic beads seems best option for cushioning. Or a mix of calcium and beads.

I have no smalls in my obsidian batch running now. I don't like and have no use for smalls. But, I have a LOT of ceramic media in the barrel (and plastic pellets!) to make up for it.
ETA: I'll try to remember to post a picture of the barrel contents next clean out. I am going from 60/90 today to 120/220 without a clean out.

You a mess captbob. I could see the ceramic being a good replacement for the smalls. That first batch that I ran with broken glass seemed like a very balanced load. Running a couple of barrels of mostly larger agate rocks from the king kong grinder-no use for the small rocks, just balancing the grind for the larger rocks. That grinder makes big tumbles safely and quick, so my focus on desirable bigger tumbles. Everyone of the obsidians in the video were also done on kk grinder. where is captbob's kk grinder ?

Haven't made time for building a KK grinder yet. It's on my list (my wife hates my "list").
It sure would save me several weeks of coarse grit tumble time.

I am into those tumbles from that machine. Still learning ways to grind w/it. Odd, it is handy for loosing the trash and the fractures. And dead color spots. Most rocks end up half size from what they started. But the end product is a fine tumbled rock w/zreo defects. Not just for shaping, but quality.

Who speaks proper?Who decides what proper speech is,,,J.D Power and Associates? LOL
I think in the rough stage,"smalls" are a must.To me it doesn't matter if it's ceramic or just smaller rocks of either the same hardness or a tad softer but they should be in there to get a better,faster grind??? I hope the Preparation H isn't for tumbling purposes?I'd rater see you go back to sugar! LOL connrock

prep H for damages incurred from captbob. He has a dry wit and uses it. Yes, smalls of some sort best for coarse. probably all stages of the rotary.
