Resumo

O Museu Nacional de Al Ain localiza-se na cidade de Al Ain, nos Emiratos Árabes Unidos. Este museu preserva uma importante coleção de objetos arqueológicos neolíticos em liga de cobre provenientes de jazidas localizadas na periferia da mesma cidade. Durante o processo de conservação e restauro das peças foi detetada a presença de iões cloreto na maioria dos objetos oriundos de ecossistemas áridos da zona costeira onde foram encontrados.
Este artigo reforça a importância dos procedimentos de dessalinização realizados durante o projeto por se revelarem fundamentais para se alcançar a estabilização dos objetose assim uma preservação mais duradoura dos mesmos. O processo conhecido por B70 foi eficaz apesar de não eliminar a totalidade dos sais dos objetos, o que exige um controlo dos parâmetros ambientais para se assegurar a salvaguarda das coleções.
