I am still at it after 2 warrentee replacement tumblers from National Geographic since March plus a freebie Pro model.
I crushed tumbler size stones from rough Turritella Agates
From SE Wyoming
After 6 weeks and 5 stages of grit (60, 220, 500, & 950 course silicon dioxide then 1200 aluminum oxide polish then ‘Gem Foam’® for burnishing)
𝔾𝕠𝕤𝕙 𝕥𝕙𝕖𝕪 𝕤𝕦𝕣𝕖 𝕔𝕒𝕞𝕖 𝕠𝕦𝕥 𝕡𝕣𝕖𝕥𝕥𝕪 😉
I have never seen a cat smile before today 😸
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 💎
Back to the Laboratory 🔬 🛠 🤓
After 8 days then Stage #4 (polishing grit) is next for 10-12 days (3 batches)
𝕐𝕠𝕦’𝕧𝕖 ℍ𝕖𝕒𝕣𝕕 𝕠𝕗 ‘𝕥𝕣𝕒𝕚𝕝𝕠𝕣 𝕓𝕣𝕒𝕜𝕖𝕤’ running across the laminated dining rm & kitchen floor these kitties in Tennessee call it the ass and tail slide, taking the rugs with them before slamming into the oven or fridge 😽
Lapis Lazuli One week on 2nd Stage grit (medium coerce) tumbling 1 week to go on pre-polish then10 days on polish grit 😉
They are getting smoother and shinier 🕒 ‘𝔸 𝕨𝕒𝕥𝕔𝕙𝕖𝕕 𝕂𝕖𝕥𝕥𝕝𝕖 ℕ𝕖𝕧𝕖𝕣 𝔹𝕠𝕚𝕝𝕤’ ❗️
My refrigerator puts off 70db.
Coleman Cooler sound suppression 😉
Rough Lace agates
After first grit stage of tumbling
The first stage of grit grinds the rough edges off stage #2,#3,& #4 polish’s them into a gleaming glow ❗️
It takes about a month for the whole processes 💎
But a rock tumbler with different grits is a lot faster and more efficient ❗️
Especially if ya have a rock saw with grinder / buffer lab like I had in the ’60’s 😉
My rock collection these days.
