The mosaic is an ancient art which impacts the history of civilizations. The city of Belém po-sesses a beautiful, peculiar and rare acquis. For being so uncommon, it is not regarded as an autonomous or as well integrated art. This fact becomes visible due to the lack of biblio-graphical data and registries on the theme. This research aims to demonstrate such facts by means of a historical contextualization and a literature review that covers techniques, con-servation, common damages and frequent pathological conditions. The main focus of this study is the mosaic collection of the city of Belém /Pará. It identifies techniques, typologies, datings, physical constitutive characteristics of the employed materials. Materials and me-thods are presented starting from the samples selected. After the analysis of these samples with their features and physical chracateristics by optic microscopy the study comes to its final part, the conclusions based on the necessary preservation of this cultural asset which integrates the memory of the city.

Patologias em fachadas: análises de casos na Universidade Federal do Pará
(Universidade Federal do Pará, 2014-03-28) CARVALHO, Isabella Chaves; PICANÇO, Marcelo de Souza; http://lattes.cnpq.br/4535052395600357; MACEDO, Alcebíades Negrão; http://lattes.cnpq.br/8313864897400179
The system of external cladding of the building acts as a protective layer and contributes to the proper aspect. The facade is subject to the action of agents of degradation as one of the most exposed areas of the building, with the presence of pathology becoming responsible for high repair costs. Research suggests as a general goal, assess conditions affecting building facades of higher education in the Federal University of Pará, guided by a theoretical basis (literature review) responsible for the first information on the subject. To such as research methodology, we sought to first do a physical survey of facades of 30 buildings in UFPA, identifying cadastral records in the main degradation mechanisms. Then, after quantify / qualify the anomalies present in the sample and point out the most critical building with key injuries and their causes, listed up to this, basic intervention measures in order to solve efficiently the problem caused by proposing a document that acts as technical support for inspection of facades generally. We also used the test to characterize samples in order to prove the origins of those damages which at first could not identify the cause. The results showed that the analyzed buildings have pathological damage of different nature and degree of complexity, ranging from the most complex requiring specific tests to discover their origin, even the most simple, with scheduled maintenance can be eliminated. We conclude that much of the damage happen by human negligence, but that even with an emphasis on quality of execution in facades, there is no way rule out failures or ignore the time of use and the actions of external factors lead to degradation Nature of the building. We conclude that much of the damage happen by human negligence, but that even with an emphasis on quality of execution in facades, there is no way to reject the hypothesis failures or ignore the time of use and the actions of external factors lead to natural degradation of the building. Therefore, to prevent the early onset of pathologies in facades, bringing its useful life and reducing extra costs, it is suggested, implementation procedures based on technical standards enforcement of them, following project criteria and presenting periodic inspections so that preventive measures are taken in apt time.
