Small-scale jewellery production has the potential to drive sustainable practices through local studio craftsmanship (Craig in Metalsmith 32–38, 2008), influencing younger generations to adopt greener goldsmithing techniques and potentially impacting larger-scale manufacturing in the jewellery industry. Jewellery businesses, from small to medium scale, play a crucial role in both economic and social development. However, achieving sustainable manufacturing in goldsmithing remains a significant challenge due to material waste, reliance on harmful chemicals, and energy-intensive processes. This chapter presents a research project initiated in October 2021 at Loughborough University, School of Design and Creative Arts, which investigates alternatives to traditional soldering methods due to environmental and health concerns. The study examines the potential of an adapted flat inlay technique, influenced by the Japanese metal inlay technique-Zogan, in comparison with conventional piercing and soldering methods, particularly for producing decorative effects that involve the combination of two different metals. Both qualitative and quantitative data are collected and analysed, with findings discussed alongside limitations. The research aims to provide informed recommendations for researchers, educators, and jewellery makers, encouraging the adoption of fabrication methods that reduce environmental impact and material waste. Ultimately, the study contributes to the advancement of sustainable practices in contemporary jewellery manufacturing.
