I would like to know which abrasives to use to polish quartz in a
tumbler. I know that I have to start with a coarse grit until
finishing with a fine grit.
My questions: What abrasives should I use:
alumina (Al2 O3): what grits? silicon carbide (what grits?) cerium oxide?
Is there an internet site where to get such ? Which books
should I buy about this topic?
Please send the answer in pvt directly to my address. Thank you very
much in advance.
