Ox-horn Rulers

These rulers are decorated in flower and bird patterns using the Hwagak (ox horn) technique. Ox horn was sliced as thin and translucent as possible and the reverse side of the ox horn was painted in splendid colors. The prepared ox horn was then attached on the surface of wood. One side of the ruler bears markings in red and white along with flower designs in between the markings, while the other side has patterned flying dragons. During Joseon Dynasty, different measurement units were used depending on purpose of usage; for example, when tailoring fabric, a 'sewing ruler' was used.
