LONDON — For young craftsmen, making a name among well-established brands is perhaps the hardest part of the trade. To do so, the artisans working at London’s Goldsmiths’ Center have the backing of a group that follows the spirit of medieval guilds.

The center’s parent, the Goldsmiths’ Company, is one of the oldest livery companies, or guilds, of the City of London. It received a royal charter in 1327 to control the standard of silver and precious metals being sold through the hallmarking system. While most of London’s other medieval guilds, such as the Fanmakers, have seen their original trade disappear, the Goldsmiths’ company has kept its link to the profession. Two years ago, it opened a space for trainees and postgraduate students to work and study.

“One of the challenges in London is access to workshop space. A lot of people have been priced out of workshops,” said Peter Taylor, director of the center, which provides training to offset what he described as a decline in technical courses in mainstream education.

“They come to us for up to a year to really kick-start their business,” Mr. Taylor said of his students. “We really work with them on professional development, business practice, as well as product development.”
