Keep it Clean
Many of us love that beautiful brown pattina that forms on copper over time. It creates lovely random patterns that make your copper cookware look like a piece of art. However, leaving the oxides along with buildup of grease and carbon on your copper can negatively affect its performance. Together, these elements will form an ever growing laquer-like layer that will prevent even heat distribution, creating hot zones on your cooking vessel as well as etching your copper. These etch-marks will deepen over time and become impossible to treat without destructive welding procedures.
Keeping your copper cookware clean will prolong its life and ensure good heat conductivity and distribution throughout, delivering delicious meals every single time.
