Polishing edges - Rimless tank help

[rastaangel]

Most of the time when ive seen a rimless or euro-braced it has polished edges as there espensive, high end tank.
A edge doesnt have to be polished to be clear, it depends on how much they arris (sand the sharp, clean cut edge off) the peice will determine what the clear to frosted look of sanded glass will be. It also depends on how thick the glass is and how they cut it will determine how nice the edge will look with a arris vs a polish.
If they can do nice clean cut then a 1-2mm arris with a 400-600 grit, you would have a hard time telling the difference unless you were told...
Altho a polished edge is far stronger and more resistant to damage as its harder to knock a peice out
