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.
My most precious ‘stony’s’
rough, unpolished, but totally fine grade 😸
I opened the screen door to wheel in my garden cart from the cold night
A house sparrow flew in , 𝔹𝕒𝕕 𝕄𝕚𝕤𝕥𝕒𝕜𝕖 😼 ❗️ Washe awoke from a nap on the couch and leaping, snagged the birdy one foot lower then the ceiling🐱
I spent an hour cleaning up bird shit and feathers & bones
2 ½ story’s up on the new ‘Cat Condo’
I temporally removed the six foot tall ‘crows nest’ whilst my CPU,s where the only thing within landing distance ❗️
Seems like every thing I own has a clock, some automatically adjust to DST or ST some don’t (wish they would leave it alone) I leave my Timex wrist watch set to time zone Zulu (Universal Coordinated Time) but then I have to remember if it is winter or summer (not to hard) then to deduct 4 or 5 hours from the display ❗️ Time means nothing to Washe cat whilst he nibbles on my eyebrow at 5 AM all winter and 6 AM all summer to open up the ‘seafood buffet’ 🐱 ( And he never misses by more then 10 minuets❗️)
In 44 BC Julius Caesar was worried about other things on this date ❗️
