The holes on the XL fire grate are pretty good size so I was having a fair amount of small pieces fall through, especially when using the BGE lump as compared to wicked good lump. Picking them out of the ash wasn't practical and I was surprised by the amount so I wanted a way to get them that was easy to do. Also, I hated dumping the last pieces from a bag of lump into the Egg as they came with a lot of dust. I wanted something I could sift that would keep the usable pieces and let the dust pass through. The solution I came up with is to use an over the sink colander. The one I got has a wide grid; the holes are 1/4" x 1/4" so dust will not clog it. It also has adjustable handle length which allows it to sit on top of trash can while I pour stuff into it, yet slide away for storage.
The picture below shows sifted small pieces ready for use.
