Best way to farm Volatile Earth?

[Cephalio]

Like someone mentioned, those elementals in mt hyjal by the starting inn are good for volatile earth.

Prospecting can be profitable to just buy ore and resell the results plus you end up with tons of that stuff

1) Collect a couple of "Potion of Treasure Finding" from a friendly alchemist.
2) Proceed to Mt. Hyjal
3) Set out slightly north of teleport point to the rock elementals
4) Proceed to merc all Scolding Rock Elementals in sight and looting them

In about 4 hours worth of farming - I picked up over 1k Embersilk Cloth, over 200 Volatile Earth & assorted Volatiles, Greens & Ore from the Tiny Treasure Chests.
