These solid coloured ink sticks are traditionally used for calligraphy and chinese brush painting. To create ink from the stick, it needs to be continuously ground against an ink stone to grind up the pigment and then a small quantity of water is added in order to make the ink. This ink can then be picked up with a brush and used directly onto a surface. 

Each coloured ink stick has a gold dragon painted on one side. The colours included in this set are Red, Yellow, Green, Blue and White. These five colours have significance within Chinese culture - Red, corresponding with fire, symbolizes good fortune and joy. Yellow, corresponding with earth, signifies neutrality and good luck. Green/Blue is generally associated with health, prosperity, and harmony. White corresponding with metal, represents gold and symbolises brightness, purity, and fulfilment. 

The colours can be used on their own or mixed together to create new shades and tones.
