Grit Table / naturals / Guangxi (广西)
Product, no published size
Natural stone
The maker states no particle size. Anything shown is our inference, drawn as such.
Each grade below shows its size in microns, its spread (the published distribution, where a maker or standard gives one; most makers publish none), and where that size lands on the reference scale, a shared yardstick for reading grit numbers across makers.
Range 1 to 2 µm. none-published.
