got a tumbler and still in the learning process....some of the bottles are coming out great, just cloudy..like a milky cloudiness on the glass.or a fog......do i need to run the bottle again with a polish?.....
I agree, But you may find it varries with different colors of glass. Takes a lot of time and documentation. RandyORIGINAL: chosi
Probably yes.
When I use 1200 Grit, which is a fairly coarse cutter, the bottle comes out resembling a frosty mug just out of the freezer. To remove the "frostiness" I tumble a 2nd time with Aluminum Oxide for at least 2 - 4 days. 2 days is usually enough, but if you take it out after 2 days and it's still frosty looking, you may end up tumbling it a 3rd time and that's a lot of work. On the other hand, if you tumble it too long, it tends to get very "mirror-like", and some people don't like that effect.Â
When I use 1500 Grit (a less coarse cutter), I find that if I just let it go for 3 or 4 days, I don't need a 2nd tumble. The Jar Doctor claims that 1500 Grit will start out as a cutter for the first 24 hours and then end up as a polisher. That doesn't seem to work for everybody, but it almost always works out for me.

You should be able to look at the bottle through a polarizing lense and see stress points in the glass which would make it unsafe to polish.
