The article delves into nineteenth-century recipes for the conservation of prints, focusing on the book “Restauração de quadros e gravuras”, written by Manuel de Macedo (a museum curator in 1884) and published in 1885.
Macedo’s treatise is highlighted as a valuable source detailing methods for cleaning and restoring prints, offering insights based on extensive experience in the field. Although this book has often been cited in scientific articles and research works, it was never properly dissected in all its parts, by its own merits, and therefore the author proposes to share the information it contains, in an effort to promote Portuguese treatises of the nineteenth century.
Macedo’s compilation stands out as a comprehensive guide to restoration techniques, particularly in the context of artistic materials and processes used in the late nineteenth century. The text underscores the rarity and significance of Macedo’s work in European print restoration literature. Specific restoration techniques discussed include the use of various materials like wax, varnishes, resins, and even unconventional substances such as blood, tea, and tobacco for treating tears, reinforcing support, and retouching.
Furthermore, the process of washing prints is detailed, highlighting the delicate nature of separating paper layers with caution to avoid damage. Overall, the article provides valuable insights into historical conservation practices, offering a glimpse into the meticulous methods employed in preserving and restoring prints during the nineteenth century.
