Further research and reading of the Four Treasures of the Study informed that the brush, ink, paper and ink stone originated in the Southern and Northern Dynasties (420-589 AD). I learned that the oldest brush dates to the Han Dynasty (202 BC-220 AD) Brushes were generally made from animal hair and in certain situations from a baby's head for good luck. Brush handles were constructed from bamboo, sandalwood, jade, carved bone or other precious materials. Innksticks is an artificial ink developed during the Han dynasty. The most desired inksticks contain musk, borneal or the aromas of Chinese medicine. The paper of highest value was that of the Jingxian in Anhui province. Some of this paper can last up to 1000 years. Inkstone is used to grind the inkstick into powder. Ideal water to use is salty water. The inkstone date back to the Han dynasty.
Its important that students understand how classical scholars used these tools in their studies. Student will certainly gain an appreciation of the Chinese traditions and culture.
