The Ceramics Seminar, held in Jakarta from 3- 7 September 1979 was the first of its kind in Indonesia. It was attended by specialists from Indonesian Institutes, the Ceramic Society and by scholars from abroad. Present were participants from the University of the Philippines, the University of Hawaii, the Chinese University of Hongkong, the National Museum of Singapore and the Muzium Negara of Malaysia. Ceramics, namely the "local ceramics" or earthenware and the "foreign ceramics" are found on nearly every archaeological site, classical or prehistoric. Foreign ceramics found on sites are considered to be of great importance for the dating of the sites. As research on ceramics is still rare in Indonesia, it is hoped that by holding this kind of seminar several problems can be tackled together.
