| 520 | _aThe primary pictorial components of two easel paintings named “San Agustín entre la Sangre de Cristo y la Leche de la Virgen” and “Agustín se presenta en una visión a Santa Gertrudis”, from 17th century were analyzed to provide relevant information to curators and restorers about Miguel de Santiago's palette, the Ecuadorian painter to whom both paintings are attributed. Three samples from each painting were collected and analyzed by FTIR and Raman spectroscopy. Also, following ancient recipes were prepared two organic dyes, the carmine lake from dried and ground cochineal insects with alum; and yellow saffron from dried pistils of saffron flowers, to compare with the samples. However, none evidenced the presence of those pigments by the used methods. The painting called “San Agustín entre la Sangre de Cristo y la Leche de la Virgen”, revealed among its components: ochre pigments (yellow and red), bone black, carbonates associated with lead white and calcite, protein binders, and vegetal oil. Moreover, this painting showed a particular compound, which was starch, being a hint of a probable restoration as from 18th century, due to literature reports. The painting materials were the same for the painting “Agustín se presenta en una visión a Santa Gertrudis”, a remarkable finding was the presence of lead-tin yellow type I and the possible existence of terpenoid resins. | ||
