Several years ago I wrote a piece called "Measure for Measure" PMI =3D
published. In preparing it I weighed out, then measured, "all" my glaze =
=3D
materials. I found that there IS a difference in the weight of some =3D
materials--clays in particular--whether the weather is dry or,--as right =
=3D
now--wet. In practice it made no difference.
It must--regretfully--be remembered that our materials change in and of =3D
themselves. There just was this thread on "different" lithiums..We have =
=3D
had those about other materials--differences in neph sy depending on =3D
place of origin, and so on. One must test each glaze if it includes a =3D
new supply of a material.
As to dust and weighing out glaze:
Get a bunch of the cheapest gallon size clear plastic bags--or save the =3D
ones bread comes in.
Adjust your scale so that it allows the bag to sit on it, without =3D
registering its weight.
Measure your ingredient out into the bag. Set aside.
After all the ingredients are in their bags, REWEIGH THEM! A simple, if =3D
primitive, way to double check that you weighed it all our correctly.
SUBMERGE each bag in a big bucket of water. Shake all material into the =
=3D
water, and remove bag. Place empty bag in to another bucket of water. =3D
Add content of each submerged bag to Bucket #1--where your glaze will =3D
be--and then put bag into Bucket #2 to be rinsed.
Next day you can siphon off the excess water in Bucket #2, allow the =3D
glaze to almost dry, add it to Bucket #1--and sieve the whole lot.
I mix up all my glazes by volume using measuring cups and the like, =3D
which are easily submerged and easily rinsed.
