All of our bronze sinks are made of tin bronze alloys, material is: 88% copper, 8% tin, 4% zinc, lead free.

They are made by investment casting, which makes good shape, perfect surface finish possible.

The process we make cast bronze sinks is the same like others else, but when we treat the surface to achieve the patina, ours is different.

We put the sinks into the kiln under very high temperature(about 400-500 centi degree), so the patina of our bronze sinks is different from others, it will hardly fade off and take off during usage, because it is applied by high temperature.
