Appearance Residential Kitchen Be ready for spots to appear on the copper countertops within the first few weeks of use. Usually the first marks will occur near work areas such as the sink or cooktop. As spots form, they will eventually overlap and form a mottled chocolate brown look. Frequency of cleanings, minerals in the water and type of use will all play a role in how it looks in your kitchen. All of the countertops on this page began with our Non-directional Matte finish. Note: See our Care and Cleaning page for a better understanding of what to expect. Restaurant or Bar With heavy use and frequent cleanings, a week or two of use will make the bar top look like it has been there for decades. People can't resist touching it and it makes any environment a memorable one. The best part is that copper is non-porous. Tip: See our Gallery for more images Outdoor Kitchens If used near an ocean where it will be in salty air, a whitish green powder will form through oxidation. With heavy use and frequent cleaning, as in most hospitality settings, this coating is not likely to form. In dryer air, the copper surface will turn brown with class and natural beauty.
