| dc.description.abstract | ABSTRACT: The patination of silverwork to modify surface color and finish became increasingly popular in 19th-century Europe, particularly among renowned artists such as René Lalique (1860-1945), Henri Vever (1854–1942), and Georges Fouquet (1862–1957). This decorative technique is typically achieved using sulfur-based solutions, resulting in blackish or bluish silver sulfide patinas¹. Patinated silver surfaces often exhibit a characteristic glossy finish, while environmental degradation typically results in a dull, matte appearance, creating visually heterogeneous surfaces that require conservation actions (Fig. 1). However, the chemical similarity between artificial patinas and naturally formed corrosion layers presents a significant challenge - Selecting a cleaning approach that effectively removes the natural corrosion without damaging the original decorative surface². | eng |
