Volcanic Ash - Item - World of Warcraft
As of Jan. 11, the inability to loot the volcanic ash is a known issue per a discussion with a GM. Someone on another board mentioned that you have to have at least the gloves if not the gloves and belt to be able to loot the ash. My druid didnt have the gloves, but was able to loot 6 before it stopped working, so who knows. Hope that helps.

Energetically modified cement - Wikipedia
Energetically modified cements (EMCs) are a class of cements made from pozzolans (e.g. fly ash, volcanic ash, pozzolana), silica sand, blast furnace slag, or Portland cement (or blends of these ingredients). The term "energetically modified" arises by virtue of the mechanochemistry process applied to the raw material, more accurately classified as "high energy ball milling" (HEBM).

Volcanic ash - Wikipedia
Volcanic ash is formed during explosive volcanic eruptions, phreatomagmatic eruptions and during transport in pyroclastic density currents. Explosive eruptions occur when magma decompresses as it rises, allowing dissolved volatiles (dominantly water and carbon dioxide) to exsolve into gas bubbles. As more bubbles nucleate a foam is produced, which decreases the density of the magma ...
