Pyrography, better known as wood burning, is an art form that has been around for hundreds of years. Recently, a new variation has evolved – solar pyrography. In solar pyrography, artists burn designs into wood using a magnifying glass to concentrate the sun rather than a heated wire or metal rod. Some examples can be found on the web galleries of Bud Hnetka and Jonathan Beartusk. The portraits by Beartusk are incredible. They are so detailed, they resemble antique photographs. I would have to guess that many hours of work go into creating one of these portraits. You can watch artist Art Blakey create one in this youtube video.
