Sieve 80 Mesh

Sieves are usually made from nylon or stainless steel wires. They are available in varying degrees of fineness and sizes are quoted according to the size of the opening or in wires per inch. Sieves used by potters usually have plastic or stainless steel frames. Common sieves are available to 80-100 mesh (wires per inch).
Wires become too fine to see somewhere beyond 100 mesh.

Screens are also used in the production of raw materials and prepared bodies, glazes and engobes.
They often have rectangular openings that follow material flow.

Slurries pass through sieves better when they have a higher water content and are not gelled.
