The Rotary sieves are great for fast sieving of glazes without wrist strain. The Talisman screens can be interchanged between the Rotary and Standard sieves, which is an advantage if you have multiple sieves. The Talisman Studio sieve fits on smaller size buckets. While the Cole LLC Lab sieves do not have removable screens, but they fit most 5 or 3.5 gallon buckets.
Lower number meshes are coarser and are typically used for clays and slips. High number meshes are finer and used for glazes. The number (40, 60, 80, 100) represents the number of wires in the mesh per linear inch.
