Hi All,
At my raku party a this weekend a friend asked if I could help her
locate a recipe for Josh's Idiot Raku glaze. She's had her nearly gone
batch for several years now and has lost the recipe in the meantime.
Anyone able to help?
TIA

Judith Enright is looking for a volcanic looking glaze.
By mixing grog of different sizes into your glaze you can get a variety of
interesting textured, cratered, and lumpy effects. I use it often in luster
glazes to add more depth and interest and to heighten the reflective
qualities of the surface! Mix the grog only into what you are planning to use
during that glazing session.

with a metallic sand finish. I fire this on dark stoneware (Death Vally -
doubt if you have it in Holland, but you surely have something similar). I

Silver nitrate is poison and corrosive. In solution, if spilled, it stains
the surface a revolting liver colour forever. If splashed on hands or
skin...liver again for many weeks. Rehearsal for age spots.
Crystals are the way to go.
Silver nitrate crystals are weighed by grams and added to distilled water.
The ratio is one gram to 10 mls of water. So 5 grams go into 50 mls. etc.
Store the dissolved solution in a coloured bottle and keep it out of light.
When measuring the solution to be added to your glaze WEAR RUBBER
GLOVES,CLOTHING YOU HATE and open the windows wide. This stuff doesn't smell
at all but it's powerful .
Add the needed amount to the MIXED and SIEVED glaze and stir carefully. It
will make the texture of the glaze peculiar at first, sort of curdled but
keep on stirring and it will smooth out. Wash the stirring implement
thoroughly especially if it's metal. This glaze is best painted on in three
smooth coats. Use a special brush for this glaze as it will be perm. stained
black.

I saw a woman firing raku, five years ago or so, using this glaze and it
came out a lovely burgundy matt. I just recently got my raku kiln up and
running and my first try with this recipe yielded a glossy green :-? It
was suggested to me to fire it to a lower temp and to reduce it in a
smaller chamber. At any rate, this is the recipe and any other suggestions
to make it "work" would be welcome.

I'm new to ClayArt and a novice potter. My potting pals and I are
experimenting with raku and are very much interested in a matt glaze. If
any of you have a basic recipe to share I would truly appreciate it. Thanks
in advance.
Bert A Stevens on sat 14 mar 98
try 35% lithium, 30% colemanite(gerstle borate) 35% bone ash, add 6%coper
2% ritile, 1/2% cobat makes a cone 08-06 raku the lithium and colemanite
may have to be adjusted, more colenmanite will make it less matt, and make
it less likely to run, firing in light reduction or oxitation gives
brighter colors

I am a high school art teacher. We do raku firings on a regular basis.
Three of our matt glaze formulas which we like seem to degenerate after
a few months and we dont know why???
The formulas all contain bone ash. Could this be the problem? For
example, one of the formulas is:
Rinbow Glaze
Gerstley Borate 3200 grams
Bone ash 800 grams
add: copper carbonate 120 grams
copper oxide 40 grams
Another is;
White Matt
Gerstley Borate 3200 Grams
Nepheline Syenite 800 grams
Bone Ash 720 Grams
The formula is fine when mixed and placed on bisqueware. After a few
months the glaze, when placed on bisqueware, separates and falls off
when fired. What could be the problem?? If anyone knows please respond.

Hi,
I am wondering if anyone out there knows of any Raku glazes that can =
be applied with a slip trailer so that the glaze will stay on the pot =
without spreading or running. In more or less of a bead look. I am not =
sure whether there is a special recipe or there is something that you =
can add to a favorite glaze to make it have this quality. I tried =
looking in the archives with no luck. Thanks in advance to all who can =
help.

Use a frit-based glaze*. Anything with gerstley borate in it is going to
bubble, flow, and ruin the design. My experience indicates that the frit
glazes stay where put. Frit glazes dry to a very powdery surface. You cannot
reliably put anything over top of them. If you insist on applying something
over top, do it while the frit glaze is still wet and the two glazes at
least have a chance of sticking together. Also, you probably will want to
add some CMC or similar material to harden the glaze somewhat.
Bruce Girrell
* Typical frit glaze recipe:
Ferro frit 3110 or 3134 100
Opacifier (tin oxide/Zircopax/etc) 10
Any other colorant you want as needed
Bill Merrill on sun 4 mar 12
Since there is a discussion about Raku...here is a very low firing glaze
that Richard Behrens developed to be similar to the old Raku glaze
develop near Kyoto . The rocks used to make the glaze was pounded rocks
from the Kamo River and those stones were lithium based. The glaze
melts at cone 016.
Frit 25 Pemco I used Frit 3304...43.6 I have used many frits
that worked in place of the original ones used by Behrens.
Frit 3134 Ferro I used 3110...26.3
Lithium Carb 9.9
China clay 6.2
Flint 14.
Coppper will make a floating green and can go red in reduction: Kenzan
made an apple green with copper. =3D20
The lithium has several advantages. Like the original glazes had lead,
lithium lowers the melting point of the glaze. It also allows a wider
range of temperature, and does not liberate any poisonous gases, like
lead does
This melts at about 1640-1650 degrees Fahrenheit.
