There are many methods to forming metal into a final shape. We have chosen the method of milling from solid 6061 aluminum using a cnc machine in our shop in Brooklyn. All other metal eyeglass frames on the market are cast or bent.
Machining from solid is much stronger than casting, also allowing for a wider range of shapes. Machining is a time consuming and expensive process but we strongly believe it creates a superior product. On the majority of the surface of our Kingsland frames you will see a tight pattern of lines. Each line is the mark of a small tool following the surface of the frame and the finished surface is a combination of those tightly spaced cut paths — over 500,000 on each pair of glasses frames. We believe that truth in process and materials is beautiful, so we have chosen not to remove the cut marks. They are a unique and authentic mark of the milling process.
Another great aspect of aluminum is that it is highly recyclable. 73% of aluminum ever produced is still in use. All the material we cut away is recycled and recycled aluminum requires 5% the energy of mined aluminum.
