Tuff

Tuff (from the Italian tufo) is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash is compacted into a solid rock in a process called consolidation. Tuff is sometimes called tufa, particularly when used as construction material, although tufa also refers to a quite different rock. Rock that contains greater than 50% tuff is considered tuffaceous.

Tuff is a relatively soft rock, so it has been used for construction since ancient times. Since it is common in Italy the Romans used it often for construction. The Rapa Nui people used it to make most of the moai statues in Easter Island.

Tuff can be classified as either sedimentary or igneous rocks. They are usually studied in the context of igneous petrology, although they are sometimes described using sedimentological terms.

Volcanic ash

The material that is expelled in a volcanic eruption can be classified into three types:

  • Volcanic gases, a mixture made mostly of water vapour, carbon dioxide, and a sulfur compound (either sulfur dioxide, SO2, or hydrogen sulfide, H2S, depending on the temperature).

    Tuff

    by: Ace Cannon

    When you say it's dead and gone, yes, I know you're wrong
    Cut and slash, sharpest knife, it won't die
    Poison cup, drank it up, it won't die
    No fire, no gun, no rope, no stone, it won't die
    Why you gotta shove it in my face?
    As if you put me in my place
    'Cause I don't care if you or me is wrong or right
    Ain't gonna spend another night in your bed, in your bed
    Laws of man, are just pretend, they ain't mine
    Love so good, love so bad, it won't die
    Some talk too long, they know it all, I just smile and move on
    Words ain't free like you and me, I don't mind
    Why'd you have to be so mean and cruel?
    The dogs are loose I'm on to you
    You ball and chained together from the dawn to dusk
    Can't call it leavin', 'cause it's just, I never came
    I never came, I never came, I never came
