Mesh sizes

All powders have a particular particle size, usually referred to as a mesh size. This is an indication of what size sieve (or mesh) it will pass through. The higher the number the finer (or smaller) the particles are. Therefore, a 60 mesh powder is coarser than a 300 mesh powder. As an example, a good average for G&G is 80 mesh, we do go as low as 60 mesh on some powders and up to 300 mesh on others. The accompanying PDF gives all the sizes. File:Mesh size chart.pdf
