  • All about iron handles Vintage French Copper

    Jun 20, 2020· Based on what I have seen, cast iron handles for French cookware appeared in the 1890s and had supplanted wrought handles by the 1920s. It is simply so much more economical to cast hundreds of identically perfect handles in a day rather than laboring over pieces one by one, and cookware handles are cast in iron, steel, or brass to this day.
