Bulletin Number Four 1986

1. Research on methods for dating stonewares and porcelain in order to cover the dating of all types of ceramics. 2. Measurement of environmental dosage on gamma radiation at various sites in Hong Kong. 3. Research and experiments to verify the unified model postulated by Dr. Chuang and to explain puzzles still extant in the field of TL research. The completion of the above work will lead to the establishment of a standard method for dating all types of ceramics. It is anticipated that this will be achieved in early 1987. By then we shall be able to commence dating service of ancient ceramics for the public and to conduct collaboration projects with other institutions in the neighbouring countries. —Philip Y.C.
