For separating fine snuff from the coarse bits after grinding.

What to look for
Sieves are sold by mesh number or by micron size. Each recipe names the micron size it needs, so check that before you buy a sieve. An ordinary tea strainer gives a coarse snuff.
Small aquarium sieves sold for hatching brine shrimp (artemia sieves) are a low-cost alternative to lab sieves, and the listing gives the micron size. A tea ball works for coarse snuff too, and so does a pair of tights stretched over a jar of ground tobacco and shaken.
Tip the ground tobacco onto the mesh a spoonful at a time and tap the rim to move it through. Grind whatever stays on top again.
