Abstract(s)
A limpeza de superfícies pictóricas com sistemas gelificados tem vindo a levantar diversas questões e opiniões contraditórias que se prendem com a deposição de resíduos de alguns componentes dos géis, nomeadamente os surfactantes, nas superfícies tratadas, e com potenciais riscos que ditos sistemas gelificados podem apresentar para os materiais constituintes das pinturas. Propôs-se neste artigo fazer uma revisão generalizada da informação já publicada acerca dos resíduos de géis, numa tentativa de informar outros colegas da profissão acerca deste assunto e assim fomentar tomadas de decisões mais esclarecidas relativamente a uma das operações que mais riscos apresenta para uma pintura: a sua limpeza.
The cleaning of pictorial surfaces with gelled systems has been raising various issues and opposite opinions regarding the presence of residues, namely of the surfactants, and whether or not they present any risks to the painting materials. In this article, a general review of the information already published about the residues in gelled systems is proposed, thus attempting to inform other conservators on this subject and encourage clearer decision-making about the operation which most risks presents to paintings, their cleaning.
