Esculturas em bronze da Praça Coronel Pedro Osório, Pelotas, RS: uma metodologia de conservação à partir de um estudo de caso.

Abstract

This research proposes a diagnosis methodology related to the conservation of outdoors bronze sculptures from a case study. Located on Colonel Pedro Osório Square, the core of the historical center in the city of Pelotas, Rio Grande do Sul, the seven bronze sculptures were produced by reputed artists and are part of the city's cultural heritage, under historical and artistic values. The bronze sculptures are inflicted by several pathologies, in a state of continuous degradation due to the exposure to the outdoor environment, vandalism and the lack periodical conservation. In addition to a historical reseach, the stages of this work included in situ organoleptic exams on the seven artworks. In one single sculpture, exams of chemical composition analysys towards the base metal were performed through sample extraction and tests of cleaning solvents on general and superficial dirts. From the achieved results, a work methodology was elaborated in order to be practiced on future conservation procedures towards outdoors bronze sculptures related to cultural heritage.
