Stain

A stain is a discoloration that can be clearly distinguished from the surface, material, or medium it is found upon. They are caused by the chemical or physical interaction of two dissimilar materials. Staining is used for biochemical research, metal staining, and art (e.g., wood staining, stained glass).

Famous quotes containing the word stain:

    It is extraordinary how the house and the simplest possessions of someone who has been left become so quickly sordid.... Even the stain on the coffee cup seems not coffee but the physical manifestation of one’s inner stain, the fatal blot that from the beginning had marked one for ultimate aloneness.
    Coleman Dowell (1925–1985)

    The nightingales are singing near
    The Convent of the Sacred Heart,

    And sang within the bloody wood
    When Agamemnon cried aloud,
    And let their liquid siftings fall
    To stain the stiff dishonored shroud.
    —T.S. (Thomas Stearns)

    No more be grieved at that which thou hast done,
    Roses have thorns, and silver fountains mud,
    Clouds and eclipses stain both moon and sun,
    And loathsome canker lives in sweetest bud.
    All men make faults, and even I in this,
    Authorizing thy trespass with compare,
    My self corrupting salving thy amiss,
    Excusing thy sins more than thy sins are:
    William Shakespeare (1564–1616)
