Bottle of Essence
A Bottle of Essence is a potion with no effect, being used only as the base for creating Essence Effects.
Brewing
The Essence of any item can be extracted into a Potion of Latent Eyedentification using a Brewing Still. For example, a Stone block distilled into a Potion of Latent Eyedentification becomes a Bottle of Stone Essence. A Name Tag that has been named will distill into the Essence of that player.
Usage
Bottles of Essence are used as the base for brewing Essence Effects. For example, brewing a Scaffolding into a Bottle of Stone Essence creates a Potion of Stone Formation. Using a Bottle of Dirt Essence would give Dirt Formation instead.
