Here I will introduce some process of manufacturing mirror etching stainless steel decorative:
Metal is metal with a unidirectional satin finish. It is produced by polishing the metal with a 120–180 grit belt or wheel then softening with an 80–120 grit greaseless compound or a medium non-woven abrasive belt or pad. Brushing gives metal a distinctive look, as it retains some but not all of its metallic luster and is given a pattern of very fine lines parallel to the brushing direction.
The coloring of stainless steel can be achieved by chemical surface treatment which actually modifies the surface oxide film on the metal. The colored finish is attractive but susceptible to finger-marks, which results in a color change and is not hard-wearing, and this should be considered when deciding on the use. The process uses acidic solution which, due to the variances in composition of the stainless and the process variables, can be guaranteed to be the same every time.
A sandblasting setup usually consists of three different parts: the abrasive itself, an air compressor, and a blaster nozzle. For etching and small object cleaning, a workstation to hold the piece of glass is also needed, as is some sort of collector to gather up excess dust.
