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.

“Ashtrays to cry into,
the suffering brother of the wood walls,

the books, each a contestant in a beauty contest,
the black chair, a dog coffin made of Naugahyde....”
—Anne Sexton (1928–1974)
