- Solid ink sticks are one of the greatest inventions in ancient history because they allow
knowledge to propagate to further generations; more benefits include easy transportation,
long-term storage, and mass production. The solid ink-sticks are made from soot, animal
glues, and, if necessary, small amounts of fragrance. The ink-sticks are identified as pine
tree soot, vegetable soot, or mineral types. To scientifically understand the traditional ink
stick, it is important to distinguish the different kinds of soot used. The present work
introduces Ultra small angle neutron scattering (USANS) and Small angle neutron scattering
(SANS) techniques to characterize the size and the spatial distribution of soot in the solid
ink sticks. We will discuss the preliminary results and the neutron scattering techniques.
The proposed methodology can also be extended to characterize the soot trace of letters
written in calligraphy and ancient documents. This enables us to track the history of
traditional ink sticks in a chronicle manner.
