Resumo Este artigo considera o artesanato produzido a partir da cultura material arqueológica, especialmente as categorias que compõem essa produção: réplicas, híbridos e objetos derivados. Com base nos objetos artesanais que reproduzem a iconografia da cerâmica Marajoara, reflito sobre o seu papel no estabelecimento de diálogo com o passado. Concluo que as inconsistências criativas do artesanato não deslegitimam a relação com a materialidade arqueológica e com o passado.

Abstract This paper considers the handicraft produced based on archaeological material culture, especially, the categories that constitute this production: replicas, hybrids and derived objects. Based on the handcrafted objects that reproduce the iconography of Marajoara ceramics, I reflect on their role in establishing dialogue with the past. I conclude that the creative inconsistencies presented in the handicraft do not delegitimate their relationships with the archaeological materiality and the past.

The paper summarizes the initial results of a public archaeology project undertaken at Vila de Joanes, a fishing village in the Amazon, on Marajó Island, where I conducted research with a site that was a religious mission from the XVII century. By reflecting about the local communities’ ideas about the site I explore the underlying logic of collecting artifacts -a local practice- and the subsequent organization of "small collections," arguing that collecting in this context should not be considered "destruction" but rather as a particular form of heritage appropriation. By exercising such reflections the study aims to better understand the relationship between small scale communities and archaeological patrimony in the Amazon as well as to aid in the development of distinct public policies which are appropriate for local preservation.

El propósito central de este artículo es exponer los resultados iniciales de un proyecto de arqueología pública realizado en Vila de Joanes, un pueblo pesquero en la Amazonia, en la isla de Marajó, donde hice la investigación arqueológica en el sitio asociado a una misión religiosa del siglo XVII. A partir de las ideas de la comunidad local acerca de este sitio se estudió la lógica que subyace a la colección de artefactos, una práctica local, y la subsecuente organización de "pequeñas colecciones". En este contexto se argumenta que este acto de coleccionar no debería ser considerado "destructivo" sino una forma particular de apropiación de su herencia cultural. A través de esta reflexión, el objetivo de este estudio es entender las relaciones entre pequeñas comunidades locales y el patrimonio arqueológico en la Amazonia, como así también aportar al desarrollo de políticas públicas distintivas, apropiadas para la preservación del patrimonio local.

O artigo apresenta os resultados iniciais do projeto de Arqueologia Pública conduzido pela autora em Joanes - uma pequena vila de pescadores na ilha de Marajó, estado do Pará, Brasil -, considerando as ruínas de um sítio histórico (PA-JO-46) associado a uma missão religiosa instalada na vila por volta da segunda metade do século XVII. As reflexões sobre as percepções das comunidades locais acerca do sítio sublinham o entendimento da lógica subjacente ao ato de colecionar artefatos - prática local comum - e à formação de pequenas 'coleções domésticas'. Meu argumento é de que o colecionamento, nesses contextos, não pode ser classificado como ato de destruição, mas como uma forma singular de fruição do passado e do patrimônio. Acredito que essa discussão contribua para a compreensão das relações entre comunidades de pequena escala e o patrimônio arqueológico na Amazônia.

The paper address the preliminary results of the Public Archaeology project that is being conducted by the author at Joanes, a small fishermen village in Marajo Island, state of Pará, Brazil, considering the ruins of an historic site assigned to a religious mission from the late XVIIth Century. The reflections about the local communities' perceptions of the site highlight the underlying logic of collecting artifacts - a local common practice - and the subsequent organization of small 'domestic collections'. I argue that collecting in these contexts should not be regarded as looting or destruction, but as a singular form of heritage and past appropriation. I believe this discussion will contribute to the understanding of the relationship between small scale communities and the archaeological heritage in Brazilian Amazon.

Electrodeposition of polypyrrole films on aluminum from aqueous solutions containing p-toluene sulfonic acid and pyrrole was performed by cyclic voltammetry and galvanostatic technique. The influence of applied current density on the morphology of the films was studied by Scanning Electron Microscopy. The films displayed a cauliflower-like structure consisting of micro-spherical grains. This structure is related to dopand intercalation in the polymeric chain. Films deposited at higher current density were more susceptible to the formation of pores and defects along the polymeric chain than films deposited at lower current density. These pores allow the penetration of aggressive species, thereby favoring the corrosion process.
