Bentonite is an absorbent aluminium phyllosilicate, essentially impure clay consisting mostly of montmorillonite. There are different types of bentonite, each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminium (Al). Experts debate a number of nomenclatorial problems with the classification of bentonite clays. Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. However, the term bentonite, as well as a similar clay called tonstein, has been used to describe clay beds of uncertain origin. For industrial purposes, two main classes of bentonite exist: sodium and calcium bentonite. In stratigraphy and tephrochronology, completely devitrified (weathered volcanic glass) ash-fall beds are commonly referred to as K-bentonites when the dominant clay species is illite. Other common clay species, and sometimes dominant, are montmorillonite and kaolinite. Kaolinite-dominated clays are commonly referred to as tonsteins and are typically associated with coal.
I walk among the withered graves
Through the corridors of time
Halls cast in iron and stone.
I speak through the darkness of my soul,
I see a flame flickering in a distant corner
Like the beacon among the stars,
upon the nightblue sky
Far away on tracks unveiled
Beyond the treasures of history
Whispering to me... as the wind among the trees
With the tone of the soft, complaining flute
Thine eyes mirrored in chaos
Exposing thy very self
In the night I shall come to you
An image by your thoughts created.
A child born in thy mind
Created by the illusions of life
So far away from reality
All are forsaken
Take a step through the mirrored halls
The corridors of time.
Voices echoing
From the walls screaming
Telling tales lost in time
Tormention in ages we dimly remember
A distant light shimmering
As one walk through the catacombs
Into the endless spheres
The rays enlightening the void of life
Echoing voices in the dark
Oh How the wounded cries
Twisted voices never fade
Resounding through eternity
No describing words
Into the endless spheres we float
Entranced by the beauty of the tormented spirits
