Excavations at Kouphovouno (Laconia, Greece) have revealed burnt deposits associated with firing structures. The ‘millefeuille’ (vanilla slice) observed was composed of alternating layers of burnt red aggregates and white carbonate. Their description, micromorphological study, and contrast with a more standard structure of the Middle Neolithic allow us to interpret the layers as belonging to a structure for firing pottery: a covered clamp. This study has clarified its method of construction, operation, and use within a domestic context. After heating and cooking, the production of pottery and lime was one of the pyrotechnological activities most consumptive of energy among Neolithic communities, yet direct evidence for firing installations has been elusive. A new approach to the problem of locating pottery firing sites is presented here. The firing of pottery seems the most likely use for this type of structure, though the production of lime is also discussed.

Celtic field research has so far been strongly focused on prospection and mapping. As a result of this there is a serious lack of knowledge of formation and land-use processes of these fields. This article describes a methodological case study in The Netherlands that may be applied to other European Celtic fields in the future. By interdisciplinary use of pedological, palynological and micromorphological research methods the authors were able to discern five development stages in the history of the field, dating from the late Bronze Age to the early Roman Period. There are strong indications that the earthen ridges, very typical for Celtic fields in the sandy landscapes of north-west Europe, were only formed in the later stages of Celtic field agriculture (late Iron Age and early Roman period). They were the result of a determined raising of the surface by large-scale transportation of soil material from the surroundings of the fields. Mainly the ridges were intensively cultivated and manured in the later stages of Celtic field cultivation. In the late Iron Age a remarkable shift in Celtic field agriculture took place from an extensive system with long fallow periods, a low level of manuring and extensive soil tillage to a more intensive system with shorter fallow periods, a more intensive soil tillage and a higher manuring intensity. There are also strong indications that rye (Secale cereale) was the main crop in the final stage of Celtic field agriculture.
