Towards the Preservation and Dissemination of Historical Silk Weaving Techniques in the Digital Era

2019

Historical weaving techniques have evolved in time and space giving as result more or less fabrics with different aesthetical characteristics. These techniques were transferred along the main silk production centers, thanks to the European Silk Road and creating a common European Frame on themes and techniques. These had made it complicated to determine whether a fabric corresponds to one century or another. Moreover, in order to understand their creation, it is necessary to determine the number of weaves and interlacements that each textile has, therefore, mathematical models can be extracted from these layers. In this sense, three dimensional (3D) virtual representations of the internal s…

A funerary perspective on the Bell Beaker period in the Wester Mediterranean Reading the social context of individual burials at La Vital (Gandia, Va…

2013

[EN] The discussion about social dynamics in recent Pre- history is supported by the study of funerary practices. The presence and significance of individual and collec- tive burials in Final Neolithic/Chalcolithic societies in the southeast of the Iberian Peninsula provides new evi- dence for the debate concerning the emergence of social inequalities in this region. Our contribution is based on the recent discovery and excavation of several individual pit burials in domestic contexts at the site of La Vital (Gandía, Valencia). The particularities of the identified burials (different ritual episodes) and their content (Bell Beaker pottery, metal objects, animal offerings) together with an …

Documenting carved stones by 3D modelling – Example of Mongolian deer stones

2018

Rock art studies are facing major technical challenges for extensive documentation. Nowadays, recording is essentially obtained from time-consuming tracing and rubbing, techniques that also require a high level of expertise. Recent advances in 3D modelling of natural objects and computational treatment of the modelled surfaces may provide an alternative, and reduce the current documentation bottleneck. The aim of this study is to examine the extent to which such treatments can be applied. The case study presented here concerns the famous deer stones erected by ancient Mongolian nomad populations. The 3D acquisition workflow is based on structure-from-motion, a versatile photogrammetric tech…

Conflicting needs of the thermal indoor environment of museums: In search of a practical compromise

2008

Thermal indoor microclimate conditions in museum buildings refer to two important requirements: the preservation of works of art and the comfort of visitors to these buildings and/or those working inside them. Unfortunately, different works of art have different internal parameters which render the management and control of the indoor thermal microclimate difficult. In this work the values proposed by various standards for the thermal environment of museum buildings have been revised. Moreover, the indoor microclimatic conditions relating to people's comfort have been described, with the aim of singling out possible common ranges for these parameters. With this aim, a useful simultaneousnes…

Control of indoor environments in heritage buildings: experimental measurements in an old Italian museum and proposal of a methodology

2005

Abstract This paper describes some results from an experiment carried out regarding a procedure to be adopted for temperature and R.H. monitoring of indoor spaces designed for exhibiting events, such as museums and similar institutions. The monitored data employed in this study has been collected by the Department di Ricerche Energetiche ed Ambientali of the Universita degli Studi di Palermo in co-operation with the Regional Gallery ''Palazzo Abatellis'' of Palermo. The study analyses a simple method for characterising the environmental quality of museums so as to ensure the optimal conservation of works of art. This methodology is based on the procedure (where thermal and hygrometry parame…

Two operative risk indicators as tools for negotiating contracts between curators of Museums and HVAC technical services providers

2020

Abstract The purpose of Heating, Ventilating and Air-Conditioning (HVAC) systems in museums is to properly control important microclimate parameters; such systems, in fact, apart from ensuring the visitors’ wellbeing, are requested to guarantee suitable indoor conditions for the proper conservation of the important cultural goods hosted by museums. Hence, in case of disservice, or interruption due to maintenance interventions, it is important to quantify the economic damage induced to exhibited and/or stored works of art (or even to the building museum itself). Accordingly, it is essential to guarantee the shortest possible period of disservice during which probable damages for the works of…

El prestigio de los objetos: mangos de marfil en el mundo ibérico

2020

El estudio se centra en una serie de mangos de marfil de características morfotécnicas similares, recuperados en espacios de hábitat y funerarios ibéricos y datados entre el s. IV y el s. II a. C. Se trata de objetos de prestigio al alcance de una élite aristocrática, que han sido elaborados con materias primas exóticas (marfil) y técnicas decorativas inusuales que indican una especialización. A través de análisis de composición por infrarrojo cercano por Transformada de Fourier (FT-NIR) y de fluorescencia de rayos X (pXRF) se ha podido documentar la presencia de incrustaciones de ámbar adheridas a la superficie de los mangos mediante el uso del estaño como soldadura blanda y el empleo de a…

A Late Roman industrial complex with glass furnaces in the northern area of Valencia

2008

Abstract Information from excavations in Conde de Trenor street (1997) and Cisneros square (1986 and 1998) has confirmed that this area situated in the north of Valencia was a river port district dedicated to commercial activities and storing goods during the Roman Imperial period and maybe also in the Republican period. At the end of the third century A.D. the function of these port buildings changed and the evidence suggests that they became industrial workshops. The bases of three circular furnaces were found with fragments of glass containers, bottles, glasses, window panes and some slag. The recent excavation which took place in 2004–2006 in the Palau Cervero , 4 Cisneros square also s…

Different methods for soluble salt removal tested on late-Roman cooking ware from a submarine excavation at the island of Pantelleria (Sicily, Italy)

2014

Abstract This paper deals with the comparative evaluation of different procedures of salt extraction designed for archaeological ceramics from submarine burial environments. The experimental work was carried out on a particular type of late-Roman cooking ware finds (Pantellerian ware) found in a shipwreck near the shoreline of the Island of Pantelleria (Sicily). The studied ceramic test-pieces were first recognised in terms of bulk characteristics (mineralogy, petrography and chemistry). SEM-EDS observation allowed verification of the presence of various secondary minerals at the surface and in the pore spaces formed after the prolonged permanence in seawater under oxidising or reducing con…
