A short answer to Johnny's question "Which quarry...": the nearest one (just check the yellow pages)....and as Lawrence notes, they all have fines.

Lawrence,

Where is the quarry you used here in NC and what type of rock do they offer? Didi you use "fines"?


All certified rock quarries in NC use linked settling ponds that generate tons of "pond fines", i.e. rock dust.
Martin Matietta-owned quarries, American Stone Co. (MM-owned), Luck's Quarry in Haw River (MM-owned) .
The one on Huhhman Mill Rd south of Burlington on 421 has granite dust., the one near Chapel Hill has volcanic tuff (2nd
hardest rock in NC) dust and one near Hillsboro has Pyrophyllite dust - really fine stuff, no pun intended.
