Final answer:
A hairbrush often is an oval brush with a mixture of boar and nylon bristles, while traditional brushes had handles made from materials like bamboo or wood and used animal hair for the bristles. Lampblack and binders would be used to create the inks needed for calligraphy and brush painting.
Step-by-step explanation:
A hairbrush is generally an oval brush with a mixture of boar and nylon bristles. Traditional brushes were often crafted using natural materials such as bamboo, wood, or porcelain for the handles, and selected animal hair for the bristles. For the creation of inks, lampblack and binders were combined and formed into sticks or cakes that could be ground against an inkstone and mixed with water to produce liquid ink. This method of making ink was essential for calligraphy and brush painting, art forms that value the quality of the brush strokes and the properties of the ink used.
