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.
