I prefer the immersion blenders or "hand blenders" that you lower into a
container when using them. They work extremely well for mixing test-batche=

- we have several in a drawer in the glaze room at the Craft Center. I
think you can pick on up at Target or Walmart for about $25, and it should
last a long time.

locally there is no way of knowing if it will last more than a few batches.

300 g is a good size to start with because it fits inside a soy-yogurt
container and is enough to pour the inside of a mug and even dip the outsid=

of a small cup.

does anyone have a method they would like to share that is a little less of
a fire hazard than what i am doing?

thanks,

We make test batches 100 gm lots, in 250 ml plastic
cups, add 100-120 ml water. Allow to sit a while. Stir
with long-handled brush, use same brush to gently move
through 200# screen. Just enough liquid to dip one or a
few test strips in. If there are any lumpy ingredients,
such as natural bone ash, oxides, etc, they are mulled
dry, in a small mortar & pestle, with teaspoon or so of
the main test batch. This quantity of test glaze is
sufficient for extensive blends & can do the inside of
a cup, (probably not a tankard). Pilot batches, like
the 300 gms you use, are run in a 1/2 gal jar mill for
1/2 hour.

Ric --

It makes for an easy calculation, but isn't
it a little annoying to mix up two pounds of
test only to find it really isn't very good?

Steve Slatin --=3D20

Whose tests are often not very satisfying,
but who keeps trying ...

Hi Paul,

At The 21st Century Glaze Project we use a "stick blender" to mix 300g te=
=3D
st=3D20
batches. For a glaze test, I like 300g better than the traditional 100g.=
=3D
It is=3D20
somewhat more accurate (especially for when you are measuring 1/10 or 1/0=
=3D
0=3D20
gram units) and allow you to dip a larger test tile. I have been using a=
=3D
$19.95=3D20
stick blender for two years now with no problems.

You will have to give up your yogurt containers and use a container with =
=3D
a=3D20
wider base. I use plastic 1 pint deli containers that we buy for about 1=
=3D
2 cents=3D20
each. Get friendly with your local corn beef vendor and you may even get=
=3D
=3D20
them for free. These containers have a few advantages. They are easier=
=3D
to=3D20
label and a small 80 mesh sieve fits them very well.

I hope this is helpful.

all the best... Paul
