CASTING BRONZE SINKS: Xiamen Granite's unique bronze sinks are formed by using Precision Casting methods. Each bronze sink is then finished, patinated(High-temperature make the patina) and waxed by hand. Our bronze sinks have a living finish that evolves over time. All Xiamen Granite's cast bronze sinks are made from tin bronze alloys (88%copper, 8% tin and 4% zinc, lead free), that is ZCuSn8Zn4, which is equal to ASTM C90300 in USA.

Our bronze sinks have a living finish that evolves over time. Current we can provide 3 colors for you choose: "Aged patina", "Blackened patina" "Old Nickel Sliver" and "Golden Bronse patina". Prior to shipping, each sink receives a coat of beeswax containing carnuba. This gives our sinks a rich, natural luster and slows the natural oxidation process.A maintenance coat of any carnauba-based paste wax, BeesWax may be applied periodically to maintain this finish.
