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:
“Europe has a set of primary interests, which to us have none, or a very remote relation. Hence she must be engaged in frequent controversies, the causes of which are essentially foreign to our concerns. Hence, therefore, it must be unwise in us to implicate ourselves, by artificial ties, in the ordinary vicissitudes of her politics or the ordinary combinations and collisions of her friendships or enmities.”
—George Washington (1732–1799)
“In spite of his practical ability, some of his experience had petrified into maxims and quotations.”
—George Eliot [Mary Ann (or Marian)
“bodies wrapped in elastic bands,
bodies cased in wood or used like telephones,
bodies crucified up onto their crutches,
bodies wearing rubber bags between their legs,
bodies vomiting up their juice like detergent,
bodies smooth and bare as darning eggs.”
—Anne Sexton (1928–1974)
