- My tumbling process goes as followed
1. Break or cut rocks into the right shapes and sizes I want for tumbling
2. I always start in my rotary tumbler and I roll them as many weeks as necessary to remove all the flaws. In my three pound barrel I use 3 tablespoons of 46-70 silicon carbide, in my 12lb barrel I use 14 tablespoons. I roll them a week then clean and inspect them. If they need more time I repeat this process. If I have more of the material I will remove any that are ready for the next stage and add new. I normally never use any Filler or media in coarse girt.
3. Once they are shaped and all the flaws are gone I move them to my lot-o vibratory tumbler for 189-220 silicon carbide. On this stage I do 2 one day runs with 1 tablespoons of 180-220 grit. I dump them and wash between the 2 runs. I always add ceramic media when I run in my lot-o and that media stays with that batch until they are done.
4. After the 180-220 stage it done I do a burnish run. For this I dump them and wash them and put them back it the barrel to clean the rocks and the barrel really good before the next stage. For the burnish I use 1 tablespoon of borax and run 1-2 hours.
5. After the burnish we are ready for 400-600 grit silicon carbide. On this stage I use 1/2 teaspoon of 400-600 grit and 1 tablespoon of borax and run for 3 days.
6. After 400-600 grit I run another burnish stage with 1 tablespoon of borax for 1-2 hours.
7. After burnish we are ready to run 1000 grit silicon carbide. This stage is also 1/2 teaspoon of 1000 grit and 1 tablespoon of borax and it runs for 3 days.
8. After 1000 grit I run another burnish with 1 tablespoon of borax for 1-2 hours.
9. Now we are ready for the polish stage. For this stage I run micro-alumina. I run a 1/2 teaspoon of the micro-alumina and 1 tablespoon of borax and it runs for 3 days.
10. After the polish is done I run another burnish stage and the rocks are done.
Your mahogany obsidian turned out beautifully! Good job👏...After a long wait I'm finally going to run my mahogany, snowflake, and regular black obsidian! It took a while, but I finally received my Lot-O vibratory tumbler in the mail. I was on a waiting list for a while. No one had any...Can't wait to get started, too excited! 😎
I’m so pleased when I googled how to tumble obsidian yours came up the top 😂😍
The cricket was kinda relaxing. Just picture you're by a pond fishing having a blast...damn I hate winter🤣
Thanks, most mornings I don't even notice the crickets until I start recording then it seems like they know and really want to start chirping lol.
My friends & I are lucky enough to live in a state that has Mahogany, snowflake & normal black Obsidian rock. Where we go they're literally scattered all over the ground forever! We went crazy! We learned from exploring that we found 3 different kinds of Mahogany obsidian...
Our group picked up buckets of it. Can't wait to tumble mine!🙂
That's awesome!! Wish I lived in an area where I could do more searching.
Great job polishing that mahogany obsidian, really love the two colors together
Thanks. I really like that stuff to, I'm starting to like obsidian a lot.
Them are Beautiful / Gorgeous Creations
Obsidian can be made into a scalpel with a cutting edge of 3 nanometers. A strand of DNA is 2.5 nm, a sheet of paper 100,000 nm For reference, the covalent bond radius of oxygen is about .13 nm. So this is about 30 times larger than the bond between two oxygen atoms. Eye and plastic surgeons use obsidian scalpels because they can cut between cells rather than through them.
A beautiful batch!
Wow just beautiful ❤
Not bad for first time....👍
Thanks Michael!!
Really good job , that stuff can be tricky sometimes, 15 years ago I messed some up I tried to tumbler with other rocks that doesn’t work at all lol , I didn’t know you only tumble by it self , those are nice
Thanks, I was kinda nervous I've heard some stories of it being tough to polish but it turned out nice.
Those will make some very nice pendants, great job!
Thanks! I think I need to watch some more videos on pendants because I don't have a real good sense of fashion or eye for design but we are going to give it out best effort lol.
They look good. I would suggest trying some tin oxide polish. I've had very good results with it on obsidian, jasper, quartz, and petrified wood in my mini vibe.
I have some cerium I plan on trying on my next run of obsidian but I don't have any tin, I'll have to keep that in mind next time I'm ordering grit.
Try using alumin oxide at 500 grit stage and above. Will increase "shine" on your rocks.
BTW cerium oxide is great for glass and obsidian but not so for other materials. If you doubt this look at the ingrediant on glass range ceramic polish....You guessed it cerium oxide. GLASS or OBSIDIAN ONLY.
Crickets are supposed to be good luck!
How much water do you add in the vibratory stages?
Very little. I put the rocks in wet and and some with a squirt bottle like once ore twice a day.
Thank you
Hold your narrative down. You keep repeating. Video getting to long to enjoy.
@user-wj3hl4fb7f I beg to differ...
I think he did a fantastic job! For the people who are fascinated about tumbling rocks, the more information someone can obtain & for them to teach us to learn is priceless!
