Italian espresso machine manufacturer La Marzocco has introduced a new finishing technique that uses an open flame to create unique color patterns on its equipment. Developed at its Officine Fratelli Bambi workshop in Florence, the process is an alternative to traditional paints and pigments for customizing machine bodies.
The method, called the Fiammata Technique, involves the controlled application of fire to copper surfaces. The intense heat causes the metal to oxidize, which naturally produces a spectrum of iridescent hues including gold, amber, violet, and blue. According to the company, the resulting color patterns are permanent and impossible to replicate exactly, making each treated panel distinct.
This development points to a growing industry interest in artisanal customization for high-end café equipment. By treating the metal itself rather than applying a coating, the technique offers a novel aesthetic for roasters and café owners seeking distinctive hardware. La Marzocco has confirmed that a protective finish is applied after the flame treatment to ensure the durability of the surface in a commercial environment, and the technique is now a permanent part of its creative offerings.
