Frosted or shiny doesn't matter to me. I put my boolits in classes. Grade 1, 2 and 3.
If I see really good cast with no imperfections, of course that is grade one.
One or two slight imperfections are grade two.
Anything above that is grade three and goes back into the pot.
I always check the base first. If the base is not filled and uniform, grade three and back into the pot.
