A: No, you will need to get under mount clips that are specific to your countertop material.
A: This sink handles wear and tear very well over time, the living finish on the sink can get damaged, but will always come back on it's own, returning to the dark, antique look you see in the photos above. This is a copper sink so it will change different shades of color as the metal reacts with food, soap, and water. Copper only turns green in certain circumstances, in the kitchen it happens when you use harsh cleaning chemicals or let acidic food dry on the sink which is why we recommend washing the sink only with warm, soapy water and a soft cloth and just rinse the sink out after use. You can use Sinkology Copper Armor or any high grade carnauba wax on your sink to help maintain the current look of your sink, the wax makes water bead up and drain quicker while it forms a barrier on the sink, limiting the change in color on the metal. Hope that helps!
