Petrified Wood - Artificial Petrified Wood

Artificial Petrified Wood

Artificial petrified wood has been produced in a Washington laboratory. In the process small cubes of pine are soaked in an acid bath for two days, then in a silica solution for another two. The product is then cooked at 1400 °C in an argon atmosphere for two hours. The result was silicon carbide ceramic which preserved the intricate cell structure of the wood.

Famous quotes containing the words artificial, petrified and/or wood:

    Before I finally went into winter quarters in November, I used to resort to the north- east side of Walden, which the sun, reflected from the pitch pine woods and the stony shore, made the fireside of the pond; it is so much pleasanter and wholesomer to be warmed by the sun while you can be, than by an artificial fire. I thus warmed myself by the still glowing embers which the summer, like a departed hunter, had left.
    Henry David Thoreau (1817–1862)

    In spite of his practical ability, some of his experience had petrified into maxims and quotations.
    George Eliot [Mary Ann (or Marian)

    This is one of the most serious intrusions into personal life that I can think of, and it’s as bad as anything I’ve ever experienced.
    —Ellen Wood Hall (b. 1945)
