An Analytical Study of Patina Recipes With Reference to Brass Metal Sculptures

Abstract

This paper attempts to explore the new patina recipes for brass metal sculptures. It is based on experiments on new patina recipes with the help of the required percentage of chemical compositions and exploring the new way of surface treatment of brass metal sculptures in the form of texture and polish through a chemical process. This research delves into the development and characterization of innovative brass patina recipes aimed at achieving both enhanced aesthetics and improved durability. Brass, an alloy of copper and zinc, has a long history of artistic and practical applications due to its malleability, color, and corrosion resistance. The patina, a surface layer formed over time, adds distinct visual appeal and protective qualities to brass objects. Traditional patina recipes often rely on the interaction of copper with atmospheric elements, leading to variable and unpredictable results. In this study, a systematic approach was undertaken to formulate new brass patina recipes using controlled chemical reactions. By experimenting with various compounds, solutions, and application techniques, a range of patina colors and textures were achieved. Corrosion resistance testing was conducted to comprehensively characterize the developed patinas in terms of their composition, microstructure, and protective properties. The results of this research highlight the potential for customizing brass patina recipes to cater to specific artistic and functional requirements. The newly developed recipes offer consistent and controllable outcomes, reducing the reliance on unpredictable natural processes. The improved understanding of the patina's chemical composition i.e. Ferric oxide, Tin oxide, sulphate compounds etc. and structural attributes contribute to the preservation and maintenance of brass objects over time. This research not only advances the field of material science by presenting novel approaches to brass patination but also provides artisans, conservators, and manufacturers with valuable insights into creating visually appealing brass objects with enhanced durability in coastal/marine environments. The findings open avenues for further investigation into the broader applications of controlled patina formation on other metal alloys and contribute to the sustainable use and appreciation of brass Sculptures.
