GLAÇURES

- Généralités
:
-
- Ce
petit recueil de recettes Nord-Américaines de
glaçures pour cône 6 Orton a
été édifié à partir
de documents courants dans les groupes de discussions
et dans les archives de messages parus sur internet.
L'exploitation de ces recettes en Europe
nécessite souvent des substitutions. Par
exemple, le fameux Gerstley Borate très courant
dans ces recettes qu'il faudra remplacer par des
frittes très riches en Bore et en calcium...
- En
règle générale, pour chaque
matière Nord-Américaine n'ayant pas
cours en Europe, des indications de substitutions
seront fournies soit directement dans la recette soit
par renvoi vers d'autres pages du site
documentées sur ces produits.
-
- Les
frittes utilisées sont fournies avec leur
formule de Seger, ce qui permet de les assimiler aux
frittes courantes en Europe ou de procéder
à des substitutions partielles ou globales de
la base de la glaçure indiquée. Dans
tous les cas il faudra procéder à des
calculs moléculaires en tenant compte des
produits disponibles ici.
-
- Les
notes indiquées par les auteurs ou par les
personnes ayant transmis les recettes n'ont pas
été traduites. Si ce point pose
problème, il suffira de nous signaler le
n° de recette par e-mail et nous renverrons la
traduction.
-
- Les
indications relatives à la température
de cuisson sont fournies par rapport au cône
Orton.
-
- Les
auteurs de ces recettes sont cités lorsque leur
nom figure dans les documents d'origine.

- Notes
: Vary the amount and kind of
pink stain to obtain lighter
pinks. 12% of darker pink stains
will give burgundy colors. Good
as a semi?transparent glaze when
used without colorant additions,
or with other colorants or
stains, although it may craze and
be opalescent if thick. You must
use a Chrome?Tin Pink Stain to
get a good pink,
Manganese?Alumina stains don't
work well with this glaze. Also
try direct additions of Chrome
oxide and Tin Oxide ? 5% Tin and
0.15% Chrome give a nice burgandy
red. Less chrome will give
lighter pinks. Possible Health
Hazards: Flint: free silica?wear
a NIOSH approved dust mask when
handling dry material.

Notes
: MIXING: weigh ingredients very
carfully, mix in a clean jar. Premix
ontents and add distilled water,
then add 2 teaspoons CMC, shake
vigorously. Sieve two or three times
through 60 to 80 mesh screen. Store
in airtight container. APPLICATION:
stir occasionally during use, as
iron tends to settle. Apply to the
thickness of a dime by brushing,
dipping, or spraying, using clean
tools. Allow glaze to dry slightly
between coatings and to dry
completely before firing. Take care
that dust does not settle on the
surface during drying. FIRING: Fire
to cone 5 oxidation exactly, cool
normally.

- Notes
: From Harold J. McWhinnie.
Glazes of this sort can be
strongly marked with rich visuakl
textures due to their high flux
content.
- Substitutions
for albany slip: (1) barnard clay
25, (2) ball clay 12, iron 12.
Also according to a computer
analysis of the above glaze the
addition of 5 % rutile would
improve the durability.

- Notes
: submitted by Janet Price.
Doesn't add to 100 because of the
strontium/barium substitution,
the bentonite, and the ash. This
may be closer to cone 5 than cone
6 but seems to work over a range
of a couple cones. This is
Zakin's GK base with 15%
unwashed, mixed fireplace ashes,
with strontium substituted for
barium and superpax for opax. By
itself over porcelain, the glaze
is not particularly interesting.
But other
- glazes
on top of it run and drip and
blend together nicely. I've found
that if I glaze the lower 2/3 or
3/4 of a pot with a well?behaved
glossy glaze, brush a coat of
this ZGK ash glaze on the top 1/3
or so and then brush or dip some
third glaze on top of the ash
glaze, I get a nice pattern of
runs that don't go off the bottom
of the pot onto the kiln shelf
(usually). Different glazes give
different kinds of runs and bands
of different glazes are
interesting too. The few times I
tried a matte glaze on the
bottom, the pots cracked. Could
have been coincidence. But I've
been sticking with glossy glazes
on the bottom since
then.

gr bentonite , for blue add .5%
Cobalt Carbonate AT cone 4-5 these
glazes are a wonderful matt; higher
they turn 'glossy'. I especially did
not like the green at this
temperature - too hard and glassy
looking. These recipes came from
Capilano College in North Vancouver

- Notes
: I have never ommitted
Barium in this ^4-^8 oxidation
glaze actually i have not used
the glaze in years. But it is a
great oxidation glaze and I
considered using it next year at
the school where I teach.
However, the barium scared me. IF
barium Carb can not be ommited is
there a safe substitute -

- Notes
: I was looking for something
like Warren MacKenzie's Glassy
Green that would fire at ^6
instead of ^4. The Boron Lithium
in Chappel's glaze book looked
close so I added the same oxides
as MacKenzie uses in his ^4.
MacKenzie doesn't use his ^4
anymore, but found a ^1 glassy
green he uses instead. This is
also a nice transparent ^6
without colorants.

- Notes
: I'm sending this to the
group rather than directly
because
- it's
such a nice glaze some others
might like to have it too. It's
cone 6, from Coopers Electric
Kiln Ceramics, Vol.2, p122.
Called
- "Mexico
Point Green". It's a lovely soft
matte green on the
white
- burning
stoneware I use. submitted by Dan

: Finely Textured Satin matt
- Do not apply too thick as
it
- will
bubble. I substituted Rutile for
Titanium Dioxide because
I
- didn't
have any and it worked fine. Just
don't double dip
unless
- glaze
if very thin. I liked how this
worked over texture.

- Notes
: In oxidation at C6, It is a
transparent green that
crackles.
- In
reduction, at C6, it will turn
blood red if heavily reduced,(
has a tendency to run).
- In
reduction, it works best at C10,
a beautiful purple.

- Ball
Clays Nord Américains :
- (Explications
d'Édouard Bastarache, edouardb@colba.net
)
-
- les
ball clays américains ont la formule
générale suivante :
- SiO2
59.25%
- Al2O3
36.19%
- Fe2O3
0.91%
- TiO2
1.71%
- CaO
0.23%
- MgO
0.23%
- K2O
1.03%
- Na2O
0.46%
- Point
de fusion : 1710 °C
-
- Les
ball clays anglais sont un peu différents
:
- 1 -
Ils sont plus plastiques
- 2 -
Ils contiennent peu de d'oxyde fer comparativement aux
ball clays américains.
- 3 -
Ils contiennent par contre de très grandes
quantités de carbone qui disparait à la
cuisson.
-
- Le
point de fusion moyen des kaolins est de 1785
°C
-
- Donc,
il est vrai qu'ils sont des argiles très
plastiques mais, il faudrait aussi dire qu'ils sont
très réfractaires.
- Ici
quand on manque de kaolin pour une glaçure, on
le remplace par un ball clay.
