Memórias ancestrais, traços contemporâneos e aspectos comunais na arte cerâmica Mbyá-Guarani

A análise acadêmica ora apresentada reflete a pesquisa vivencial que, como investigador do Programa de Pós-Graduação em Artes da Universidade do Estado do Rio de Janeiro (em sua linha de estudos em Arte, Cultura e Cognição), aferi em aldeias Mbyá-Guarani nas cidades de Niterói e Maricá desde o ano de 2012 a respeito de sua arte em barro. Com aportes etnohistóricos da sua cerâmica ancestral, esta ação foi assim realizada por levantamento de dados tanto pré-históricos quanto históricos focados sobre si. Porém, reconhecendo a escassez de seu fabrico entre aqueles Mbyá e, paradoxalmente, que ainda existam em seu meio mostras de que os artefatos de barro permanecem memorialmente sendo importantes para esse povo, tal exame não se restringiu a conhecer apenas a morfologia desses objetos, mas procurou vislumbrar um tanto de sua simbologia e recuperar essa ocorrência prática por meio de atividades artístico-pedagógicas junto às crianças dali. Portanto, através da pesquisa-ação e do método educativo de Célestin Freinet se buscou apontar oportunidades de revitalização dentro da sociedade Mbyá dessa memória do exercício de construção oleiro e de seu devido valor às suas crianças

ESPIRITUALIDADE E ARTE: Um estudo do Processo de Transcendência na Produção e Contemplação da Cerâmica

O presente estudo, objeto desta dissertação de mestrado, visa demonstrar a transcendência que ocorre na produção e contemplação da cerâmica. Em outras palavras, apresentar o vínculo entre Espiritualidade e Arte e, para tanto, os conceitos sobre espiritualidade pontuados por Leonardo Boff e de Meishu-Sama constituem os pontos de apoio para o estudo. Acrescentamos igualmente as considerações de Meishu-Sama relativamente à arte, as quais constituem a forma central para estruturação da pesquisa. Todo o processo de produção da Arte Cerâmica desde a escolha da argila até as queimas é descrito na dissertação. Concomitantemente, a fase de contemplação da obra é igualmente levada em consideração a partir do resfriamento do forno até o encontro do ceramista com sua obra. Paralelamente à teoria acerca da transcendência, espiritualidade e arte, fotografias explicam as fases do fazer cerâmico, e peças de cerâmicas auxiliam na compreensão do que pretendemos analisar a presença da espiritualidade durante a produção de uma obra artística aqui, mais especificamente, a cerâmica.

Light curing through glass ceramics: effect of curing mode on micromechanical properties of dual-curing resin cements

OBJECTIVES The aim of this study was to investigate micromechanical properties of five dual-curing resin cements after different curing modes including light curing through glass ceramic materials. MATERIALS AND METHODS Vickers hardness (VH) and indentation modulus (Y HU) of Panavia F2.0, RelyX Unicem 2 Automix, SpeedCEM, BisCem, and BeautiCem SA were measured after 1 week of storage (37 °C, 100 % humidity). The resin cements were tested following self-curing or light curing with the second-generation light-emitting diode (LED) curing unit Elipar FreeLight 2 in Standard Mode (1,545 mW/cm(2)) or with the third-generation LED curing unit VALO in High Power Mode (1,869 mW/cm(2)) or in XtraPower Mode (3,505 mW/cm(2)). Light curing was performed directly or through glass ceramic discs of 1.5 or 3 mm thickness of IPS Empress CAD or IPS e.max CAD. VH and Y HU were analysed with Kruskal-Wallis tests followed by pairwise Wilcoxon rank sum tests (α = 0.05). RESULTS RelyX Unicem 2 Automix resulted in the highest VH and Y HU followed by BeautiCem SA, BisCem, SpeedCEM, and finally Panavia F2.0. Self-curing of RelyX Unicem 2 Automix and SpeedCEM lowered VH and Y HU compared to light curing whereas self-curing of Panavia F2.0, BisCem, and BeautiCem SA led to similar or significantly higher VH and Y HU compared to light curing. Generally, direct light curing resulted in similar or lower VH and Y HU compared to light curing through 1.5-mm-thick ceramic discs. Light curing through 3-mm-thick discs of IPS e.max CAD generally reduced VH and Y HU for all resin cements except SpeedCEM, which was the least affected by light curing through ceramic discs. CONCLUSIONS The resin cements responded heterogeneously to changes in curing mode. The applied irradiances and light curing times adequately cured the resin cements even through 1.5-mm-thick ceramic discs. CLINICAL RELEVANCE When light curing resin cements through thick glass ceramic restorations, clinicians should consider to prolong the light curing times even with LED curing units providing high irradiances.

Light curing through glass ceramics with a second- and a third-generation LED curing unit: effect of curing mode on the degree of conversion of dual-curing resin cements

Objectives The aim of this study was to measure the degree of conversion (DC) of five dual-curing resin cements after different curing modes with a second- and a third-generation light-emitting diode (LED) curing unit. Additionally, irradiance of both light curing units was measured at increasing distances and through discs of two glass ceramics for computer-aided design/manufacturing (CAD/CAM). Materials and methods Irradiance and spectra of the Elipar FreeLight 2 (Standard Mode (SM)) and of the VALO light curing unit (High Power Mode (HPM) and Xtra Power Mode (XPM)) were measured with a MARC radiometer. Irradiance was measured at increasing distances (control) and through discs (1.5 to 6 mm thickness) of IPS Empress CAD and IPS e.max CAD. DC of Panavia F2.0, RelyX Unicem 2 Automix, SpeedCEM, BisCem, and BeautiCem SA was measured with an attenuated total reflectance–Fourier transform infrared spectrometer when self-cured (negative control) or light cured in SM for 40 s, HPM for 32 s, or XPM for 18 s. Light curing was performed directly (positive control) or through discs of either 1.5- or 3-mm thickness of IPS Empress CAD or IPS e.max CAD. DC was analysed with Kruskal–Wallis tests followed by pairwise Wilcoxon rank sum tests (α = 0.05). Results Maximum irradiances were 1,545 mW/cm2 (SM), 2,179 mW/cm2 (HPM), and 4,156 mW/cm2 (XPM), and all irradiances decreased by >80 % through discs of 1.5 mm, ≥95 % through 3 mm, and up to >99 % through 6 mm. Generally, self-curing resulted in the lowest DC. For some cements, direct light curing did not result in higher DC compared to when light cured through ceramic discs. For other cements, light curing through ceramic discs of 3 mm generally reduced DC. Conclusions Light curing was favourable for dual-curing cements. Some cements were more susceptible to variations in curing mode than others. Clinical relevance When light curing a given cement, the higher irradiances of the third-generation LED curing unit resulted in similar DC compared to the second-generation one, though at shorter light curing times.

“Let the American potter be a professional amateur" Laura Anne Fry and the American art pottery movement

"Artist Laura Anne Fry blended the concepts of professional and amateur, and helped raise the merit of ceramics in the United States. Fry influenced American art pottery with her contributions to Rookwood Pottery of Cincinnati—changing the course of the company. Her successful experiments with decorating techniques helped Rookwood become a national leader in art pottery, and eventually led to over a decade of controversy between Fry and Rookwood"

Promoting interculturalism through art education : a case study Portugal and Latvia

This study examines art student’s awareness, understanding and practices of intercultural art education in higher institution of art. Specifically, the research focused on Art Academy of Latvia, Riga. The purpose was to promote “interculturalism’’ among students and to acquaint them with the knowledge and skills of developing and reflecting on their cultural values and that of others’. For 10 weeks, 7 students in the Art Academy of Latvia explored the Traditional African Ceramics. My research included data gathered from student questionnaires, class discussions, interviews, observations, student artwork and photographs from their personal activities. I likewise took note of the students’ practical works and their approach to African-based ceramics. First, in literature review, I discuss my purpose of study, why the study is important, limitations, statements of problem, and further research. Secondly, I examine culture and paradigms of cultures, comprehensive context of the African history and traditions of the African ceramics, the importance of intercultural art education. Then, I describe how the case study in Latvia was carried out among 7 participants’ who are students from 2nd year – masters’ level. The case study involved 7 students from the department of graphics, glass, ceramics and painting with the aim of promoting intercultural learning among art students. The case study reveals participants’ attitude towards intercultural education and reveal the importance of intercultural education in higher institutions of art as well as other institutions of learning. Although the participants were positive attitude towards other culture, the study reveals that creating awareness through intercultural art and exposing students to other culture enhances their creativity ability to explore other culture and they are more likely to be opened in sharing their experiences and their cultural perspective. Experiencing culture based- art create awareness of other cultures
