Premium burls have been selected and cut for maximum color and grain patterns. A burl results from a tree undergoing some form of stress. It my caused by an injury, virus or fungus. Most burls grow beneath the ground, attached to the roots as a type of malignancy that is generally not discovered until the tree dies or falls over. Burls yield a very peculiar and highly figured wood, prized for its beauty and rarity.
Many of our burl pen blanks are stabilized by injecting an acrylic resin. This virtually eliminates the biggest problem with burl turnings, checking and cracking due to expansion or contraction.
