Apache Tear Rock Tumbling Polish Trick ⚗💎

Mohs (scale of harness) 5  They are to soft to tumble in stage #1 Course grit (60/90 Silicon Dioxide) The stones would have 30% of their size ground away  ❗️

Soo…I start them on stage #2 Medium grit (170/220 Silicon Dioxide for 4 to 5 days instead of 7-8 days )

Then stage #3 Pre-Polish grit (500+ Silicon Dioxide for 4-5 days)

Stage #4 Polish grit (1200+ Aluminum Oxide for one week (Al O¹ breaks down after 7 days of tumbling)) So clean and add fresh polish and run another 7 days if needed.

Now Stage #5 Gem-Foam ( Magic little ‘sponge cubes’ ⚗❓) for 2 or 3 days and your rocks will come out shinier then ‘oleo’ on a glass door knob whilst not slippery to the touch 😉

Big Hammer for making tumbler size stones out of large rocks ❗️ Tumbler size stones cost $30 a pound. Precious rock comes in bulk chunks (up to 6LB for only 4 dollars 💎
Stay Tuned for more translucent polished Apache Tears stones from New Mexico polished right here in N.E. Tennessee 🤠 (7 days AL O¹ + ‘Gem Foam’ 3 days = 10 days max) 😉
I will rinse them if I deem necessary , If they are dun tumbling 😉



Agate polishing 💎

After stage #4 last polishing grit 10 days of tumbling (#1000 aluminum oxide) they were kinda dull looking

after Burnishing with ‘GemFoam for 2 to 3 days

Much much shinier 🙂

After 50+ years I got shinny rocks again 😉

💎A lapidary rock (wet) saw costs $ 500 – $6,000 chuckies 💰

So I purchased an eight dollar ‘Cold Chisel’ that will work just fine for me  ⚒

⚠️ Wear safety glasses (place a rag over rock)

I have to run my stones for 3 days with ‘GemFoam’ and water to get them shinny, as recommend by National Geographic ❗️

 

I am adding ceramic ‘filler pellets’ media next tumble

ceramic pellets

The final stage will be 3 to 5 days using ‘GemFoam’ media which should shine them rocks up 👌

Rock Tumbler change day 💎

My Last batch of rocks for final polish will tumble for 10 days.

They are not finishing as expected . I will try a different grit of Silicon Dioxide SiO² & make them rocks shine 😉

They are not as shinny as this one from near sixty yrs ago 💎

just started last batch of stage #3 (pre-polish grit) 𝕋𝕦𝕞𝕓𝕝𝕚𝕟𝕘 𝕊𝕥𝕠𝕟𝕖𝕤 ℙ𝕠𝕝𝕚𝕤𝕙𝕚𝕟𝕘 𝕚𝕟𝕥𝕠 𝔾𝕖𝕞𝕤 💎

After 8 days then Stage #4 (polishing grit) is next for 10-12 days (3 batches)

Polishing Agates

After tumbling for a week with medium grit (stage 2) These will now go through one week of pre polish then 10 days of polishing grit (stages 3 & 4)

Rock Tumbling grits (Silicon Carbide) milled variations there of 90/75 coarse then finer variation for polishing ;)

Silicon carbide is one of the hardest-known materials with a Mohs Scale hardness of 9+. This hardness gives it the ability to cut tumbling roughs such as agate, jasper and petrified wood, which have a Mohs hardness of about 7.

Angular Particles:   When crushed, silicon carbide breaks into angular-shaped particles with sharp points and edges. This gives it an effective cutting and grinding ability when it is caught between tumbling rocks in tumbler barrel.

Inexpensive:   Silicon carbide is inexpensive, selling for just a few dollars per pound as a screened and packaged product.

The combination of hardness, angularity and low price make silicon carbide an excellent abrasive for rock tumbling, gem cutting and lapidary work of all kinds. Silicon carbide granules are also used for sand paper, sand blasting, water-jet cutting and many other purposes.
