Writing Utensils Celadon

The literati of the Goryeo dynasty enjoyed writing prose and poetry
so they equipped themselves with a diverse range of cherished writing
utensils including paper, brushes, inksticks, and inkstones. Among
the Goryeo celadon writing utensils that have survived to today, water
droppers that were used for pouring water onto the surface of an
inkstone are highest in number.
