Pyrography or pyrogravure
is the art of decorating wood or other materials with burn marks resulting from
the controlled application of a heated object such as a poker. It is also known
as pokerwork or wood burning.
The term means "writing with fire", from the
Greek pur (fire) and graphos (writing). It can be practiced using specialized
modern pyrography tools, or using a metal implement heated in a fire, or even
sunlight concentrated with a magnifying lens.
When wood becomes art
Pyrography is entirely a craft. The wood is not colored, but it is the
pressure of the red annealed top on the wood and the residence time that
determines the shade and marking of the engraving.
