National Geographic stage #4 Si O (silicon oxide 1800 grit ) is cool but not sufficient. I use AL O ² ( aluminum dioxide 2200 grit ) and it even feels waxy for shining 🙂
rough Mambamba Jasper (crockadile stone)
Leopardite after stage 2
Finished Apache Tears (still need some enhancements)
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)
I have never seen a cat smile before today 😸
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 😽
Mixed assortment of Aventurine, Sodalite, Dalmatian Jasper, Rose Quartz, & Agate
These are after 5 days of the coarse grinding grit (stage 1) removed the rough edges.
I have 5 batches ready for medium grit (stage 2) {7-8 days each}
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.
