Resumo

A termografia por infravermelhos (infrared thermography – IRT) é uma técnica não destrutiva e não invasiva que oferece a possibilidade de estudar a superfície das esculturas para a detecção de características e anomalias, tais como delaminação, estratigrafia, preenchimentos e defeitos. O IRT tem sido amplamente utilizado em edifícios e grandes estruturas, assim como em obras de arte como esculturas e pinturas em bronze. Este artigo descreve a aplicação de termografia infravermelha activa, utilizando uma câmara manual de baixo custo, no exame de esculturas de gesso, um material ao qual ainda não tinha sido aplicado. Em particular, foi utilizado em duas esculturas em gesso de finais do século XIX, da autoria do escultor português António Soares dos Reis, como parte de um extenso projecto dedicado ao estudo da sua obra (GEO-SR). Os resultados indicam que é uma técnica com um grande potencial para detectar alterações debaixo da superfície, permitindo um novo olhar sobre a sua construção e conservação.
