BLUE EFFECT ON HANDS
This type of coating provides an exact reproduction of the traditional bluing applied to steel hands, with the advantage of flexibility in terms of choice of the hand’s constituent material.
The color blue can be applied to copper alloy hands pre-treated with a galvanic under-coat, or hands made from gold, titanium or any other type of metal. Hence finishing operations such as diamond polishing or faceting can be performed. In addition, this treatment has proven to be highly stable, with its color not changing over time.
