Rocks to Avoid Tumbling

Тәжірибелік нұсқаулар және стиль

Do you ever wonder which rocks you should pick up on the beach and which ones you should leave behind? In this video, I'll show you how I decide which rocks would probably not do well in a rock tumbler. Then I'll tumble those poor choices so you can see how rocks like those will turn out.
Thanks to Christina Jelinek for doing the closed captions for this video. If you would like to help out with the closed captions, let me know.

    It was funny that as I watched you reveal the tumbled rocks, I thought that even with the pitting and undercutting, that many of them looked great to me. Then when you pulled in the ones you showed as examples of great tumbling results, it was clear what you look for in your final product and the other ones clearly didn't measure up. Great video.

    Fir me the allure of tumbling has never been about making the rocks look “perfect” but to just see the potential of the rock’s character, to see what unique qualities you can bring out of a piece! And a lot of the rocks here are perfect examples! Sure, everybody and their brother has shiny rocks, but finding and working something into a one of a kind palmful of art? That’s my goal! There’s certain qualities of the rock you can’t see unless you break it, tumble it, etc!

    I enjoy the process of tumbling more than the finished product. But for me, the challenge is to make them look as perfect as I can. I realize that not everyone has the same goal as I do. The problem is that I tend to show only those perfect examples on my channel. I thought people should know that not all rocks turn out perfect.

    Well, I have just learned I'm not as much of a magpie as I thought. 😆 While the batch is not as shiny as your usual, I still think the tumbling was worth it for the color and patterns, particularly the one with the crystal pockets. (This is probably why I love geodes so much.) I was happily shocked that the specular hematite stayed intact. I was expecting glittery slurry. And on the one with the big hole...I like the contrast that tumbling created. The hole is the most interesting part of that rock, and the contrast makes it pop out, so to speak.

For the porous stones I mix stone powder of similar hardness with slow drying epoxy, submerge the rocks and stick them in a vacuum pump container for thirty minutes and remove them before it hardens. Tumble on!

    Just catching up on rock tumbling videos and your stink stone caught my eye. I actually like it. Those holes give it an interesting look. If I were tumbling it, I would use my water pic to blast out those holes. That's much quicker than a sewing needle. This process only works because my husband and I each have our own water pic. He would not appreciate it if I used a shared tooth implement on rocks.

    hey rob, so i’m a beginner for tumbling completely, i’m gonna order one of the national geographic tumblers the hobby edition one, as you said in your review the polish is really bad, so i figured i’d get that separately. i found one that looks okay and i wanted your take on it, for step one it’s silicon carbide F80, step two is silicon carbide F220, step 3 is silicon carbide F400, and finally instead of aluminium oxide is ‘pumice powder’, i remember you saying that aluminium oxide is really good for step 3 and 4 so should i go for a different one?

    My bete noir is ruby in zoisite. I know there's a way to tumble it and get a shine. My brother-in-law who is a geologist collects spheres and has a beautiful shiny one. The problem for me is that I keep trying to polish it (ruby in zoisite) over and over again. So if you have any ideas, I hope someone out there might have a hint or 2. 🙏 Thanks for the video.

    I have only seen pictures of that, never tumbled it myself. I just looked up the two minerals and found that zoisite is 6-7 and ruby is 9 on the Mohs scale. I think that's your problem. Silicon carbide and aluminum oxide are both 9 also, so they're going to have a hard time with the ruby, but will easily wear the zoisite. That's going to cause undercutting, or uneven wear on the two different minerals. Your brother in law's sphere was not tumbled. It was probably ground with diamond grinding cups. Some rocks will turn out much better on a cabbing machine or some sort of grinder than they will in a tumbler.

    Thanks for the demonstration! Someone who really likes granite or other rocks that undercut in later stages could just stop at 220 in a vibratory tumbler and do the rest by hand or treat with mineral oil to enhance the color like I do. I try to be picky about the granite I pick up and only take home more unusual pieces I feel are worth spending a little extra time on. My guess is that coarser grits still work in the tumbler because they’re enough to cancel out the undercutting whereas the finer ones don’t impact the shape enough.

I am a geologist by training, though it has been many years since I worked in that profession. May I share a tip for cleaning grit out of the pits and holes that you had in some of the rocks? A dedicated WaterPik will help blast into the holes to loosen and remove the grit efficiently. That particular brand (maybe other brands too) can be fitted with different nozzles that focus the spray for different spray intensities, and the flow volume can adjust as well. Thanks again for the informative video - so much fun to watch. It brings back great memories of the rock tumbler we had in school.

The one petoskey stone can be saved but the other wasn't worth the time to pick it up in the first place let alone put it though the tumbler. Granites don't normally polish very well so. while there is pitting in the ones you polished, they are better than I thought they would turn out.

    In terms of visual perfection, I see your point regarding tumble-ability. But, using the “not awful” ones as my example, the others are great because you can see how beautiful the colours and patterns are without wetting them down. Especially the granite. So, the objective will for me determine whether to tumble. On a cold winter night, a bowlful of gorgeous coloured and/or patterned rocks that have been tumbled is a calming and cheering thing to spend an hour or two with. Ditto for a stressed-out me at any time of year. Love your videos; it’s a bit like listening to my own mental commentary.

    @@n1nj4l1nk Most of the time, "media" refers to either small pieces of ceramic or plastic beads that are added to a rock tumbler. They have a couple purposes; they cushion the rocks so they don't bang into each other so hard, and they fill in the nooks and crannies which helps the grit grind against the stone better. Grit is the abrasive that's in the barrel. Two of the most common abrasives are silicon carbide and aluminum oxide, which is what I used in this video. Using more grit than rocks is something I have never heard of anyone doing. However, if you're tumbling a rock that is prone to fracturing or is soft, or has large flat surfaces, then using more media, like ceramics, is a very good idea.
