WOOD SPECIES EXPLAINED
Curious why some woods resist dents better? The Janka hardness scale measures a wood’s toughness by testing the force needed to embed a steel ball halfway into it—named after Austrian researcher Gabriel Janka. Ratings range from soft pine (around 380) to tough hickory (over 1,800), guiding my choice of wood for durable heirloom furniture. Check out our site to see how these ratings shape my custom builds!
White Oak
White oak (Quercus alba) is a premium hardwood native to eastern and central North America, characterized by its light to medium brown heartwood with occasional olive or grayish tones, and a coarse, straight grain that often features ray flecks for a distinctive quartered appearance. It has a high density and is renowned for its exceptional strength, with a Janka hardness rating of about 1,360, making it highly resistant to wear. The wood contains high levels of tannins, which contribute to its natural resistance to decay, fungi, and insects, and it has closed pores that enhance water resistance.
