To create gold vermeil, the item is first crafted in fine or sterling silver and is then covered in gold using the process known as electrolysis. Tidigare, vermeil was crafted using the process of fire-gilding, but this was later banned due to the dangers inherent in this process, especially the issue of mercury causing blindness. Electrolysis, if done correctly, results in a consistent thickness and quality that is capable of lasting for a very long time, and can last for many years.
