Wooden shapes (x3)

Wooden forms were used to teach solid geometry and mathematics in schools from the late 19th century to the first half of the 20th century. Three turned shapes—a sphere, a truncated cylinder, and a cone—crafted from three types of wood: pear, walnut, and corm tree, each with its own story to tell. Some species, like the service tree, are becoming increasingly rare, while others are still part of our daily lives. The wood is carefully selected by artisans committed to supporting sustainable forestry and respecting the environment.
