Experiments on micrometer and nanosizes of shale and lateritic rock as colorants on canvas / Hushinaidi Abdul Hamid

Malaysian lands are very rich in natural resources especially
Shale and Lateritic rocks. The transformations of coloured
rocks to colorants for artwork can give a huge impact for
the government, industries and consumer. This research
project aimed to process and produce natural colorants
from shale and lateritic rocks into two sizes which are in
micrometer and nano size range. X-Ray Fluorescent (XRF)
was carried out to identify element content in each rock
whilst Field Emission Scanning Electron Microscopy (FESEM)
was performed in order to determine the sizes of the rocks after grinding accurately.
