Beadblasting

Hi - I’ve read that some of you are using beadblasters in your work.
Just wondering how useful you find them and when you use them… What
finishes are they best for? I’m working in silver and would love to
be able to get a finish as much like untouched cast silver (a sort of
slightly frosty matte, I guess) as I can. Any ideas or comments?
Planning to buy a blasting cabinet this week so please speak now if
this is not a good move!

Thanks in advance

Joseph
