How to do a Sieve Analysis
· Most assay labs report the results of a screen analysis in mesh size instead of microns. The range of sizing usually is between 65 mesh and 325 mesh. As a point of interest, 400 mesh is so fine that cold water won''t go through it. Gasoline will, this means that if you have gas that has water in it gently pour it through a 400 mesh screen.
