The Junglans nigra L. of the Juglandaceae family known as Canaletto Walnut is known for its beauty and preciousness, particularly common in the eastern regions of the United States.

The name of the Tabu 51.028 veneer comes from the internal channels that carry chlorophyll, and it is recognizable from other species of Walnut by its pronounced grain and overall darker coloration.

Throughout history it has been used by many great artists, including Leonardo da Vinci and Rembrandt, and even today it remains a prized wood.Among its various historical uses it was used in North America as a dyeing element to dye wool a dark brown/black color, and the same dyeing process was later used, after the discovery of the Americas, in many European countries in large dye works.
