I would not recommend using the included glass catch container. The last thing you want is a glass hand grenade should something go wrong. This grinder is generating about 1/3 2F, 1/3 3F, and 1/3 fines the way I have it set right now. You can adjust the distance between the grindstones. If too fine, increase the gap. Too course, decrease it.
