My Dear friend,
Glass bead blasting is the best way to clean your gold and silver
castings with out damaging it.
Two types of glass bead blasting can be used dry as well as wet. I
am using wet bead blasting since 1992 for my gold and silver
castings.
I prefer wet glass bead blasting since there is no dust generated
and water provides a cushioning between the glass beads and casting
surface and the cleaning is of surgical quality. The surface after
wet bead blasting is clean surface which shows the defects in the
castings if any clearly.So the wet or dry glass beads blasting can
also be used as a quality control step.
I clean the wet glass beads regularly of the investment build up, so
the casting surface remains shining and not mat.But Mat surface is
some time good for some designs if no polishing is required.
Test your castings with wet as well as dry glass bead blasting, if
the jewelery tools supplier provides this test before buying the wet
or dry glass beads blaster.
Investing in a wet glass bead blaster will really prove beneficial
in long run and you will be happy as I am.
May all be free of ill will, animosity, anger, hatred.
May all develop goodwill and love, peace and harmony.
May all be Happy and liberated.
Umesh
