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.

This petrified heart has taken,
Because, created deathless,
Nothing but death remained
To scatter magnificence....”

and I will be soft wood and you the nail
and we will make fiery ovens for Jack Sprat
