how to glaze two color clay

Smith, Judy on mon 12 feb 07


Last week I had some leftover SB red clay. I decided to add it to a
lump of Bmix. The vase has a nice swirl pattern. I was thinking about
just glazing it with clear glaze, but the color contrast is not very
bright. Do any of you have suggestions on how to glaze this pot? I was
thinking about maybe glazing it with color on some part of the vase. =20

When I'm doing agateware and the swirl pattern isn't fabulous but I still
want to see that it's there, I dip the pot at an angle in a matte black
glaze and then glaze the other side with clear. It's almost like the
solid black highlights the color patterns in the clear section.

The clays when wet and you are throwing them, they get their color
on each other from the throwing slip. To brighten up the contrast,
you need to do a similar thing as done with zogan/inlay: Use a
Japanese style trimming tool, a kana, and scrape the surface of the
pot to regain the contrast between the two colors of clay.

Any transparent glaze should work, especially one that likes
to interact with iron.

I shaved the exposed surface and the agate pattern was pretty. When I
bisque fired the pot the SB red color faded. Will the SB red get darker
with a clear glaze? I am still very new to potting and do not have a
lot of experience with this clay body.

Dear Judy Smith,=20

If the surface of your pots is dull and the Agate pattern not clearly
and sharply defined it may be to your advantage to shave the exposed
surface to remove remnants of slip that remain on the face of the clay.

To begin with, stick to a clear transparent glaze unless you have
several pots to play with.

Hello Judy:

Wet the pot and you will have an approximation of how it would look with a
clear clear glaze on top.

Dear Judy Smith,

Since I have no experience of firing the clay that you use I cannot =
really say.

But you have yet to take the clay up another step in temperature and I =
do know that my terra cotta clay changes from burnt sienna to a dark =
umber if I overfire slightly. So all I can suggest is that you are =
brave, bite the bullet, and fire you pot to maturity. IF you wish to =
treat it as an experiment, glaze one side and leave the other "Au =
Natural". Otherwise, glaze all over. Or you could just put in a liner =
glaze.

Wishing you every sort of success.

All the best,

Ivor Lewis.
