The author would like to share his experiences in the study and collection of ancient Thai ceramics over more than ten years with readers and collectors about the identification of real and fake ceramics, the background of Siam (now Thailand) and Thai ceramics which are related to each other in terms of cause and effect. This book also contains articles from experts in Thai ceramics, such as Dr. Dawn F. Rooney and PariwatThammapreechakorn. The details on artifacts which were illegally found at the Thai-Burma borders are based on the information of Dr. Sumitr Pitipat. In addition, brief information on research from Dr. Roxanna M Brown that she conducted in 2004 about maritime trade and shipwrecks in neighboring countries, which provides clear evidence to precisely date Sawankhalok and Sukhothai ceramics, is also included. The usage of those ceramics which are included are based upon Mr. Thanyakarn extensive research, which proposes the use when the owner was alive as well as after he or she died. The Buddha votives are also included because most of them were created from fired clay probably manufactured at the two important kilns, Koh Noi or Payang kilns, and they demonstrate the religious beliefs of Thais at that time
