Transmute

Transmutation is a sub-skill of Alchemy. It is highly valued since it allows the transmutation of some metals into more valuable ones, and transmutation of some elemental items into harder to find ones.

Requirements
All transmutations require the alchemist to have a or any of the variants of the  equipped or in his inventory.

Most transmutations are on a shared cooldown. The length of the cooldown varies by recipe, but prevents all transmutations until it has expired (including those which would initiate a shorter cooldown). Of note, however, the following transmutations do not have a cooldown:
 * Transmute: Arcanite and Transmute: Titanium
 * Transmute: Elemental Fire
 * Transmute: Primal Might
 * Non-epic gem transmutes, including Meta Gem transmutes and all Cataclysm gem transmutes

Recipes
There are no transmutation recipes prior to the Artisan level.

Artisan
At 250 Alchemy, Alchemist Pestlezugg in Tanaris sells Transmute: Iron to Gold and Transmute: Mithril to Truesilver. At 275 he also sells Transmute: Arcanite which is noteworthy because it has no cooldown.

At 275, one may learn all of the elemental essence transmutes which are depicted by the diagram and outlined in the table below. These transmutes enable an alchemist to convert one type of elemental essence into another.

At 300, players may obtain Transmute: Elemental Fire from the Thorium Brotherhood with reputation. This recipe does not initiate a cooldown.

Transmutation Master
"Allows an Alchemist to sometimes get greater results when transmuting materials" - When specialized as a Transmutation Master, there is a random chance that you create more than one item when transmuting. It's possible to get up to 5 items in a single process.

It has been reported that, when averaged, Transmutation mastery grants an increase in resulting items of about 20%. Given that a single transmute can result in up to 5 items, long stretches of "no additional results" may result.
