The observation of the presence of massicot, vermilion, azurite and
gold indicates that the sculpture was actually carved in the aforementioned
period and has not undergone any recent modification, as all of
the pigments observed were used extensively during the sculpture
manufacturing period.
The results indicate an accidental mixture of massicot with azurite,
generating a green hue. This mixture was confirmed by comparing the
studied sculpture with other sculptures of Our Lady of Sorrows, which
usually have a blue mantle rather than the green mantle found on the
sculpture under study.
In addition to helping restorers choose the best sculpture restoration
procedures, the results obtained in this study also contributed to
improved knowledge of the manufacturing techniques used for polychrome
statues during the baroque period in Brazil, which produced a
large collection of religious art.
