## sieve mesh

### beardiepaw on mon 29 oct 07

Can anyone tell me about mesh sizes? I use sieves WIth 100 and 80 mesh. I
saw on ebay metal sieves thtat I would be interested in, but they give the
sizes in decimals of an inch, I think, and mm sizes, even micron sizes.
What does the 100 and 80 measure on the glaze sieves?

I never thought of it before, just took it for granted. Sher morrow

I think that mesh sizes refer to the number of holes per inch. So to
convert a decimal inch measurement to mesh size just divide 1 inch by the decimal
number. So for example, for a mesh size of 0.0165, divide 1 by 0.0165 to give
you ~60. So 60 holes per inch.

For micron sizes it would probably be easiest to go to an online conversion
calculator (_http://www.onlineconversion.com/length_all.htm_
(http://www.onlineconversion.com/length_all.htm) ) and convert the microns to inches. So
again, for 425 micron mesh, that converts to ~0.016732 inch. Then divide that
number into 1 as above to give you ~60 holes per inch.

A mesh size of 50 would be about 0.02 inch or 508 microns.
A mesh size of 80 would be about 0.025 inch or 318 microns.
A mesh size of 100 would be about 0.01 inch or 254 microns.

I think this is right...

HTH,
Leigh

Sieve data is abundantly available.
