Comparative study of protective coatings for the conservation of Urban Art
2020
Abstract Contemporary mural paintings are complex artworks for several reasons, including the heterogeneity of the materials used to make them, and the different types of substrate on which the painting layers can be applied. Currently we are focused on a technical-scientific research aimed to solve the issues related to the long-term care and maintenance of murals, by evaluating the performance of several protective coatings applied on these artworks. This paper deals with a preliminary experimentation aimed to: (a) study the interaction of antigraffiti products on common synthetic paints; (b) test the effectiveness and efficiency of several commercial products used as antigraffiti; (c) de…
New insights to assess the consolidation of stone materials used in built heritage: the case study of ancient graffiti (Tituli Picti) in the archaeol…
2020
AbstractTituli Picti are an ancient form of urban graffiti very common in the archaeological site of Pompeii (Naples, South—Italy). They are generally made of red pigments applied on walls of Campanian ignimbrite. This paper deals with a scientific investigation aimed to their conservation. This is a challenging task since it requires a multidisciplinary approach that includes restorers, archaeologists and conservation scientists. The study has provided suggestions on the proper way to conserve Tituli Picti over time. In the present work, several specimens of Campanian ignimbrite were painted with red earth pigment; lime and Arabic gum have been used as binders as well. Such painted stones …
Innovative Industrial Technologies for Preventive Anti-Graffiti Coating
2017
Graffiti is the main issue in terms of acts of vandalism with public transport. Hardly any suburban train, commuter train or goods train, hardly any engineering building, station or noise barrier wall escape graffiti spraying. This means enormous expenses every year which one would rather use to the benefit of its customers. Furthermore, the temporary and permanent anti-graffiti protection systems used up to now do not ensure adequate graffiti protection. The costs for the application of graffiti protection and/or graffiti removal to a large part depend on the circumstances of the individual case in question, i.e. on the size of the surface, the type and size of the ground, the accessibilit…

Short-term response of the Ca cycle of a montane forest in Ecuador to low experimental CaCl2 additions
2013
The tropical montane forests of the E Andean cordillera in Ecuador receive episodic Sahara-dust inputs particularly increasing Ca deposition. We added CaCl2 to isolate the effect of Ca deposition by Sahara dust to tropical montane forest from the simultaneously occurring pH effect. We examined components of the Ca cycle at four control plots and four plots with added Ca (2 x 5kg ha(-1) Ca annually as CaCl2) in a random arrangement. Between August 2007 and December 2009 (four applications of Ca), we determined Ca concentrations and fluxes in litter leachate, mineral soil solution (0.15 and 0.30 m depths), throughfall, and fine litterfall and Al concentrations and speciation in soil solutions…
CREATIVE TOOLS FOR THE FORMATION OF PUBLIC SIGNS IN THE URBAN ENVIRONMENT OF THE BALTIC STATES
2014
<p>In public space there is the information, that is always designed with a specific purpose. For example, signposts are placed to provide direction guidance and to highlight some of the most important objects. Public signs function as the visiting cards of some institution or enterprise, creating indirectly a definite image of these institutions or some ethnic or social groups, while graffiti is written to create and maintain a public image and to express emotions or attitudes towards some person, a group of people, events or processes. To achieve the expected objective the authors of signs often use the eye-catching texts that differ from linguistic and para-linguistic means, such a…
Degradation study of XVIII century graffiti on the walls of Chiaramonte Palace (Palermo, Italy)
2010
A systematic investigation of the original materials and the degradation phenomena induced by soluble salts on the wall matrix and on the graffiti of the Inquisition jails of Chiaramonte Palace in Palermo (Italy) was carried out. Built in the XIV century, Chiaramonte Palace was used as Inquisition court during the XV–XVI centuries. The ancient graffiti, recently discovered, represent a unique historical witness of the prisoners that lived during that terrible period. In order to study the nature, the amount and the distribution of the salts in the masonry, stone materials sampled at different depth from the wall matrix and saline efflorescences were analysed. Different physical techniques w…
Graffiti, Street Art, Urban Art: Terminological Problems and Generic Properties
2013
In the last ten years, street art has become a very important factor in the international art scene. It has become a precious object to buy and preserve, and yet there is considerable confusion about the generic properties and definition of street art in academic research. As a rightful part of popular culture and urban culture, street art is not pure and independent. It intertwines with different art forms and urban subcultures and nurtures spin-off production. Therefore it is quite hard to trace its borders. Street art is not graffiti. They are different visual expressions and even though they might share the same space, artists and techniques, they still produce visually and conceptually…
Inscripción árabe en la ermita de Nuestra Señora de la Vega (Torre de Juan Abad, Ciudad Real)
2019
RESUMEN El trabajo aborda el estudio de la inscripcion que ostenta una lapida de marmol conservada en la ermita de Nuestra Senora de la Vega. Ademas de editar y traducir su texto, analiza el contexto historico y arqueologico de la zona de Torre de Juan Abad y del Campo de Montiel y explora los escasos restos de cultura islamica que conservan. Se concluye que el texto esta en lengua arabe y grafia cufica simple y que fue grabado en la segunda mitad del siglo X sobre una lapida romana reutilizada. Menciona los nombres de dos varones y podria haber sido escrito por uno de ellos, tal vez encontrandose faltos de libertad. PALABRAS CLAVE: epigrafia arabe, graffiti, al-Andalus, califato, Campo de …
Cuatro cerámicas con epigrafía árabe del Museu de Borriana
2021
En este trabajo se da a conocer una muestra de las más destacadas cerámicas de época almohade que se conservan en el Museo Arqueológico de Borriana y que proceden de excavaciones arqueológicas realizadas en la ciudad y su entorno. Se presta especial atención a la decoración epigráfica pintada o incisa sobre la arcilla fresca y la estampillada. Del análisis de su decoración epigráfica se ha extraído información de notable interés que complementa aquella directamente derivada del análisis tipológico. This paper will present a sample of the most outstanding Almohad ceramics that are preserved in the Archaeological Museum of Borriana. These pieces have been found during the archaeological excav…
