The glass bead blast 'freshens' up the satin finish and makes it uniform. After the cleaning and tarnish removal there will be a lot of swirl marks or a faint, hazy, scratchy looking appearance.Chu-Jerry, that is AMAZING!!!
What does the glass bead blast do?
It seems it would remove the gold plate.
Doing it on gold plate is a delicate process. It needs to be done at fairly low air pressure. I use about 40psi in my blast cabinet, but this depends on the equipment. The glass bead media must be fresh and clean. Old media can have fractured beads with sharp edges which will be abrasive, and contaminants and debris can also cause damage. It must only be done just long enough to achieve the desired sheen without dwelling too long in one spot. This goes very quickly. The glass beading should not be used for the major cleaning, though it will reach into tight spots and can clean spots that can not be reached otherwise.
If done correctly it will not remove gold that is sound, rather it just 'taps' it down with millions of tiny smooth beads. If there is loose or flaky gold it can remove that though, but simple polishing would also do that.
