A friend asked me to post this for him.
He has a glaze that when it is freshly mixed runs through the sieve with =
=3D
little to no coaxing. Nothing remains in the sieve. What he is wanting =3D
to know is if the glaze just pours through the sieve then is it =3D
nessacary to even sieve the glaze in the first place. If yes why??
Please respond to the list, he can monitor the posts but can't get on =3D
the list for some reason.

well he has some clean, well ground ingredients... this time.
no chunks or organic contaminates....
we sieve for quality control and well mixing.. not only does sieving
take out contminates, it also mixes.
you know, stir up all the bits of stuff that make up the glaze.
gotta do it.

Test it unsieved. I fit looks fine, then no!
If not, then sieve it. Results are the only
relevant factor.

What mesh sieve? If it is pouring through an 80 or 100 mesh with no
problem I don't see the need to sieve. If it goes through a 40 then he
will want to increase the mesh.

This is the reason why we rarely sieve glazes. I find that with some
materials, including magnesium carbonate, Cornwall stone, you do need to
sieve in order to break up the particles, but otherwise, when we finish
mixing glazes with a Jiffy-Mixer, they almost always pour right through the
sieve with nothing left behind in the sieve. We always use the true
Jiffy-Mixer drill-mounted impeller-mixers, available from many ceramic
suppliers, and for mixing glazes they do a better job than any of the other=
s
I have tried, and I have tested them all extensively.

You don't say what mesh!
With Stoneware Glazes, if I sieve glazes at all it's through a 60, I don't
go finer. Ash Glazes I Ball Mill anyway, so I never sieve them.
