I am nearing completion of a study of the building materials and construction techniques of the architecture of Tsoungiza-Nemea.  One of the issues I still have to address is the variation in form of combustion features including built hearths (of which I have five types) within the LH I period and the significance of different hearth shapes.  Related to this is the question of differential use between primary and secondary hearths.  Can anyone refer me to a study on this subject, either on the Greek Bronze Age or anything ethnographic?
