Wood meal

From PyroGuide

Wood meal is a form of sawdust, that is much, much finer than your average wood particles. The easiest way to produce wood meal is with a power sanding machine, like a belt sander. Once you have sanded your wood down, it needs to be screened to filter out all the larger particles. I suggest about an 80-100 mesh screen to do this. Veline's superprime only requires about 60 mesh wood meal.
