the Black-topped Pottery in Predynastic Egypt. One of the most accomplished and sophisticated wares in ancient Egypt is the black-topped pottery that was mainly manufactured during the Amratian (Naqada I) and Gerzean (Naqada II) Periods (4000-3000 BC). This pottery has the distinctive feature of having a polished red body with black on the rim and on the inside. The greatest concern on the black-topped pottery is the chemistry used to produce the black coloring and the firing method, which have engendered much discussion and debate over the years. Based on the scientific investigations, we came to the conclusion that the black color is due to a carbon adsorption caused by the organic materials and the firing under reducing circumstances. The firing method of the black-topped pottery is, however, still in controversy. Hypotheses are generally divided into two interpretations. One is the firing in which the red of the body and the black of the rim are produced simultaneously. The other is the two-step process in which the red-hot vessel is removed from the hearth and placed immediately rim down into organic materials.
