Refining

Refining

Refining (also called affining) is the process of purification of a (1) substance or a (2) form. The term is usually used of a natural resource that is almost in a usable form, but which is more useful in its pure form. For instance, most types of natural petroleum will burn straight from the ground, but it will burn poorly and quickly clog an engine with residues and by-products. The term is broad, and may include more drastic transformations, such as the reduction of ore to metal (for which see Refining (metallurgy)).

Famous quotes containing the word refining:

    Involuntary mental hospitalization is like slavery. Refining the standards for commitment is like prettifying the slave plantations. The problem is not how to improve commitment, but how to abolish it.
    Thomas Szasz (b. 1920)

    Artistic growth is, more than it is anything else, a refining of the sense of truthfulness. The stupid believe that to be truthful is easy; only the artist, the great artist, knows how difficult it is.
    Willa Cather (1876–1947)

    The Americans ... are almost ignorant of the art of music, one of the most elevating, innocent and refining of human tastes, whose influence on the habits and morals of a people is of the most beneficial tendency.
