His paste ingredients are soy flour, lime and water. This paste is very gritty and not at all similar to Japanese rice paste. As a result Chinese stencils must be cut with larger openings to allow the less plastic paste to be deposited. Japanese rice paste is very elastic so the stencils are very fine. In the summer, after mixing, the paste can be used right away. In cold weather it should sit for a day before being used.
The stencils are made with paper soaked in tung oil. Tung oil comes from the seeds from a deciduous shade tree native to China. The seeds are rich in unsaturated oils.
Lui Da Pao uses natural indigo.
