Trella’s signature Prussian Blue patina was developed in Trella’s Brooklyn workshop in 2017 and has since been applied to a wide range of products in our collection. This specialty finish is one that develops its color, texture, and character through a process that relies on a quick direct application of patina followed by patience and timing. It is a process that once started, cannot be adjusted or altered during its natural development. The custom made patina is applied to raw brass and left to sit for hours as the transformation takes place. At the right moment, the components are then air dried and sealed with a clear lacquer to capture the desired color once it has been reached.
