Rapa Nui (Easter Island)’s Stone Worlds
No full textThis article explores the spatial, architectural and conceptual relationships between landscape places, stone quarrying, and stone moving and building during Rapa Nui’s statue-building period. These are central themes of the ‘Rapa Nui Landscapes of Construction Project’ and are discussed using aspects of the findings of our recent fieldwork. The different scales of expression, from the detail of the domestic sphere to the monumental working of quarries, are considered. It is suggested that the impressiveness of Rapa Nui’s stone architecture is its conceptual coherence at the small scale as much as at the large scale. </div

Archeometric Investigation of the Stone Tools of the Vatya Culture (Pest County, Hungary)
No full textWith the analysis of the middle Bronze Age (2000–1350 BC) Vatya culture findings in Pest county (Central Hungary) comprising of more than 400 polished stone tools and instrument tools this is the first archaeometric study with such scale in Hungary. In order to characterize petrographically the raw-material of the stone tools macroscopic and microscopic stone analyses were made together with mineralogical and geochemical analyses. In the course of the work a new digital database the Archaeometric Stone Tool Database was established. Based on the results, the material of the instrument stones is mainly sandstone and quartzite that were easy to collect from their source areas. Local volcanics, mostly amphibole containing andesite variations dominated among the material of the polished stone tools. Ophiolites (metamorphic basic rocks, serpentinized basic and ultrabasic rocks) were the raw-material of stone axes that indicate either more distant travels for raw-material or exchange import

An engineering perspective on the Industrial Archaeology of the Purbeck Stone Industry
No full textThis thesis is a study of the industrial archaeology of the Purbeck Stone Industry, set within the context of local social and economic history and informed especially by
an engineering perspective on the quarrying and mining operations. A wide range of existing published sources and archive evidence has been evaluated, placing the work in the context of existing knowledge, and an extensive field survey of stone extraction and related industrial sites in the Purbeck area has been undertaken,including the creation of a large photographic archive. Major buildings in which
Purbeck stone has been used as a constructional material have also been examined to illustrate the market for the material at various historical periods and to show
how the various types of stone were able to be used, and the relationship of potential use to methods of extraction and working. The study examines all aspects of the extraction and working of the stone in Purbeck, illustrating how masons quarried, dressed and carved the stone before it was transported to its major markets, and examines the techniques of quarrying, mining, working, carving and transporting the stone providing a much improved understanding of this neglected area of the industry. In addition, the effect of the industry on the local community is examined, and the roles of the craft guild, landowners and stone merchants evaluated and explained. The importance of transport is also stressed, and the changing technical approaches to the movement of this heavy raw material are considered. Finally the thesis explores some important aspects of twentieth century stone
production, noting the importance of changes in planning laws, apprentice training and stone conservation and how these relate to the future prospects for the industry

Tacit knowledge, learning and expertise in dry stone walling
No full textThis is a detailed study of learning in the context of dry stone walling. It examines
what happens in the learning situation. The aim of this work was:
'To understand the nature of expertise in dry stone walling, how it is understood
by those practising the craft, and how it is transmitted to others'.
The main research questions were, therefore:
What happens when dry stone wallers are learning their craft?
How do they acquire expertise in dry stone walling?
How is this learning communicated?
This process necessitated developing a way of engaging with the practitioners,
eliciting descriptive data about what they were doing, and why they were doing it,
through interviews (or conversations) with both individuals and groups, whilst
they practiced their skill. Twenty three wailers were interviewed as they worked,
building walls.
The material obtained was analysed under seven different themes:
'Knowing how'
The use of tacit knowledge or intuition
'Flow'
Constant decision making, reflection and learning from mistakes
Individual and subjective variations and experiences
The relevance of emotion
The use of 'rules of thumb' or maxims.
Learning walling does not fit simply into any of the seven themes. It is
contextualised, complex and individual. It demonstrates tacit knowledge and
intuition. It involves emotion, sometimes consciously, sometimes not. It involves
memory, problem solving, and learning from mistakes, and reflection. Maxims or
'rules of thumb' were a key element in the learning process at all stages. Linear
stages of learning were not evidenced. Deep understanding of the practice is
evidenced, and the wider learning and teaching implications are explored
