This was used in my GFO reactor. This material is very fine-grained. It can easily slide through the holes in the reactor's jaws. Luckily I had a filter sleeve over my outlet tube on the reactor to catch it all. Serves its purpose, but I have a line of defense to catch grains flying out of the reactor.
