“…The finding that neither in Experiment 2 (unfamiliar shapes thrown with familiar wheels) nor in Experiment 3 (unfamiliar shapes thrown with unfamiliar wheels) the mass of clay used to throw the vessels affected the degree of standardization of assemblages may appear surprising at first. As reported earlier (Gandon et al 2011(Gandon et al , 2013, in the present study the use of larger quantities of clay resulted in larger vessels. Because larger vessels are more difficult to throw (Roux and Corbetta 1990) one might have expected a lesser degree of standardization.…”

“…They only briefly practiced the task the day before the experiment, producing one or two vessels under each condition. ***** Table 2 about here ***** 1 The use of predetermined quantities of clay allows comparisons with the results of our earlier study on expert French potters who demonstrated mechanical optimization when reproducing the same model shapes with the same quantities of clay (Gandon et al 2011). Using two different quantities of clay ensured that for each model shape potters threw vessels of different size.…”

“…Because larger vessels are more difficult to throw (Roux and Corbetta 1990) one might have expected a lesser degree of standardization. However, part of the difficulty of throwing larger vessels resides in the stronger mechanical constraints that they engender (see Gandon et al 2011) which in turn limits the range of possible variations in shape. Within this framework it is also interesting to note that the shapes that were produced with the lowest degree of standardization, the bowl (C2 and vase (C4), were also those that have been demonstrated to deviate most from the model shapes provided (Gandon et al 2014), probably for reasons of mechanical optimization (Gandon et al 2011).…”

“…Though Middle Minoan IB as a chronological period shows the greatest degree of parity in terms of RKE manufacture proportions, the greatest diversity of RKE manufacture methods appears during Middle Minoan II. Furthermore, there is a progression in terms of vessel shapes within the Minoan repertoire over time, which may reflect a synergy of sorts between these shapes and the use of the wheel; the changing methods most likely altered the replication of particular forms, necessitating shifts in wall angles, thicknesses, and overall dimensions (a topic which is covered in much more detail in Gandon et al 2011).…”

A Re-Examination of Early Wheel Potting in Crete

The manner in which Minoan potters first employed the pottery wheel has become a matter of some debate. A growing body of work has taken a sceptical approach to the transition from hand-building to wheel-throwing techniques in a number of contexts, finding that the idea of a technological transition of this nature is not supported by the ceramic evidence. Although a small number of publications have addressed this topic as it relates to Minoan Crete, in light of the evidence from contemporary areas around the Mediterranean and Near East it has become necessary to establish firmly what types of techniques and methods were being used as potters first employed this tool. In order to assess the types of primary forming techniques used by potters during the periods between Middle Minoan IB (when the wheel was first regularly used) and Late Minoan IA (by which time vessels of all sizes were regularly formed with some type of rotation), an experimental type set was produced. Analysis was conducted by correlating the macroscopic features produced with specific forming methods, and then comparing those features against material from Knossos, Palaikastro and Myrtos-Pyrgos. The results of that comparison challenge the established notion that potters had developed wheel-throwing skills during these early periods. Instead, a more complex picture emerges which reveals a process of gradual acquisition of combination techniques (wheel and coils). The pattern of uptake indicates a level of cohesion across the potting community of central and eastern Crete, irrespective of the geographical distance between the three sites studied.The Annual of the British School at Athens, (), , pp. - © The Council, British School at Athens doi:./S

“…The Von Mises stress index [J. Lemaitre et al, 2004] has been used to measure the mechanical stress operating in the object and it has been related to the throwing difficulty, proposing thus an idea for potters' skills assessment [E. Gandon et al, 2011]. In this object-oriented approach, the pressure is measured by analyzing the mechanical characteristics of the created object after completion, and not in real-time during the creation of the vessel.…”

ACM Journal on Computing and Cultural Heritage, 2014, 7 (2 ____________________________________________________________This research has been conducted in the context of the ArtiMuse project that aims at the modeling and renewal of rare gestural knowledge and skills involved in the traditional craftsmanship and more precisely in the art of the wheel-throwing pottery. These knowledge and skills constitute the Intangible Cultural Heritage and refer to the fruit of diverse expertise founded and propagated over the centuries thanks to the ingeniousness of the gesture and the creativity of the human spirit. Nowadays, this expertise is very often threatened with disappearance because of the difficulty to resist to globalization and the fact that most of those "expertise holders" are not easily accessible due to geographical or other constraints. In this paper, a methodological framework for capturing and modeling gestural knowledge and skills in wheel-throwing pottery is proposed. It is based on capturing gestures using wireless inertial sensors and statistical modeling. In particular, we used a system that allows for online alignment of gestures using a modified Hidden Markov Model. This methodology is implemented into a Human-Computer Interface, which permits both the modeling and recognition of expert technical gestures. This system could be used to assist in the learning of these gestures by giving continuous feedback in real-time by measuring the difference between expert and learner gestures. The system has been tested and evaluated on different potters with a rare expertise, which is strongly related to their local identity.
