^6 clay bodies

updated mon 5 jul 99

 

Maria Elaine Lanza on tue 29 jun 99

I know from past postings there has been discussions about the disadvanatges
and advantages of Laguna's ^10 B-Mix clay body... but, I'd like to know what
your opinions are of the other brands such as Miller, Highwater and
Standard... don't know if there are others... for ^6 oxidation work... does
Laguna have a ^6 white stoneware that anyone has tried?

I have been using Standard's ^6 white stoneware... which I like... throws
well... ..have also tried a black clay with manganese, but am very leary of
the manganese content... may be my imagination, but my skin itches after
throwing.

The problem I have with Standard is that its manufacturer is up north...
although we have a distributor here in Florida... I suspect its more costly
than another brand produced more locally... any recommendations? Thanks in
advance, Marie Elaine

Marie, I have tried many clays for use at cone 6. Standard 112 vitrifies =
well
at 6, but can be rather stiff to throw. Standards 153 is a good buff at 6, =
but
is somewhat porous. I've tried Highwaters clays and some of the cone 10 =
clays
have a low absorption a 6 and they work well for me--Hestia, Trina Buff and
Helios. I've also tried some Laguna clay, but have not been satisfied. =
B-mix 5
was a big disappointment--warped and cracked a lot. My favorite clays come
from Kickwheel in Atlanta. I love the spotted owl for cone 6--light =
speckling
looks great with a clear glaze and it vitrifies well. They have lots of =
clay to
try and pay half the freight. If you would like some more info., e-mail me =

Have you tried "Lizella" from Lizella, Georgia? It comes right out of the
river and is great for handbuilding, some people are not crazy about it for
throwing, others love it.

I used to use Lizella and I liked it a great deal. I don't know how good
it would be for large pots, but for domestic ware, it's terrific. I fired
it to ^7 & 8, and although it was very dark, almost a chocolate brown, it
did not seem to become especially brittle, as you would expect with such a
high iron content. (This was in oxidation, of course.) I have a lasagna
pan, very thinly thrown and with a flat bottom, which has been through the
oven hundreds of times, the glaze is crackled but the pot is still going
strong.

I used it with a white slip and the texture would still break through-- it
was as close as I've ever come to the rich surfaces of reduction in an
electric kiln. If I weren't tranced out on porcelain, I'd probably still
be using it in my oxidation work.

I liked the lizella clay, color and throwing but was told by my supplier
that it never truly vitrifies even at temperature.

I don't understand this. What temperature? I fired at ^7 & 8, but it sure
seemed tight. I just went and got an old mug out of the back of the
cupboard and tried the handydandy tongue test. You apply your tongue to
the base and if you feel a sucking sensation, the pot is still pretty open.
Then you look to see if the pot absorbs the spit quickly. The Lizella mug
passed both tests, though they aren't very scientific.

I could be completely wrong, though, since it was far away and long ago.
Might be worth testing a sample for fired absorption, though. I used a
glossy glaze opacified by tin, and it was a beautiful surface, for an
oxidation-fired pot. Edges broke through a rich red brown, and the
speckling was much prettier than clays articially speckled with ilmenite
and such, in my opinion.
