Hello everyone,
I've just recently learned of at least two Albany slip-containing glazes
that are dark with GOLD FLECKS in it.
Gold flecks sound great to this Elvis kind of guy but I'm clueless. What
makes gold flecks -- crystals? puddlets of segregated something? nearby
exploding mustard dogs?
And most important, how do I get the black velvet base???

I've had glazes at cone 10 with gold flecks using a tenmoku glaze with
a rutile wash over it. This was a few years back and I don't have the
recipes. I think the rutile wash was 50/50 rutile and gerstly borate.
I also don't remember if it was oxidation or reduction. At any rate,
it's a direction to try.

Jeff,
You can get gold flecks over a tenmouku glaze by applying a wash of Dolomite
and water over the glaze. I have used this technique for the tops of lids,
but you need not be so restricted in your application. Sounds like the
tenmouku would come close to the black velvet base, but I don't know that
the dolomite qualifies as the exploding mustard dogs! Barbara

Janet Price's idea of a wash over temmoku is one approach to gold
flecks. One wash which gives gold flecks on top of a brandy
colored sea is 1/3 red iron oxide + 1/3 gerstley borate +
1/3 rutile all mixed w/ water. Wing it on how much water, weigh
out the materials. Brush on, dip rim or whatever. This is for
REDUCTION and my knowledge extends to C/9-10 only. Tried once in
oxidation & memory says "forget it" - but my memory's been wrong
before. Good luck. Karen Gringhuis

At cone 9-10 I used a simple iron/rutile wash that I have advertized on
clayart before.
The result (over my white) was a saturated iron red but sometimes, when the
gods were right (and I think the high-temp soak was right too) stunning
gold flecks or crystals would develop.
IRON RUTILE WASH
(by volume)
2 parts red iron ox
1 part rutile
bit of bentonite
Hope somebody gives it a try.

Approximately this same iron-rutile wash
was/is being used everywhere I was this
summer. There were variations in the way
it was mixed, but the results were extremely
similar, including small to large gold crystals.
The varying mixtures I've come across:
1/3 red iron, 1/3 rutile, 1/3 gerstley borate,
mixed with water and used as over-wash. Val
Cushing recommends this one. Beautiful over
both matt and glossy glazes. This one also got
tried using black iron instead of red; worked a
bit differently but still interesting.
70 parts rutile, 50 parts red iron, mixed into a
solution of 1/2 of the glaze being used and 1/2 water,
to a wash consistency. Kevin Caufield uses
this, and to remarkable effect, especially in salt
fires.
Les Beardsley in Ladysmith, B.C., uses a similar
wash over a clear gloss glaze, wood fires - gorgeous,
turns the glaze a wonderful rich rust color, with huge
gold crystals. Nice over Shaner's red, too, though
very different from the clear.

Hi...
Been reading your gold fleck in glaze with interest and believe it or
not saw one on 22 Aug at the Tozan noborigama unloading in Nanaimo
B.C.... A potter named Manabu Seki had used Les Beardsley's temoku
glaze over Death Valley Red clay and the wood firing produced just
beautiful gold flecks on the finished pot. Don't know if this can be
repeated but I am sure Manabu will be trying it again. It was
wonderful.
As Dannon Rhudy reported we had a melt down of the chimney but the
dogi and the first and second chambers came out very well. As well as
the fact there are many excellent potters who put their ware in the
dogi firing was exceptionally great.
Regards to all
Maureen in hot and sunny Ladysmith where the blight has attached my
tomatoes for the second year! yuk!

As you all can see I am way behind as usual - but I have done hundreds of
tests on Tenmokus and the only time I really got the gold flecks was when I
used MgO. I am sure it is some kind of crystal. I think the rutile works as
well but the MgO gave a different kind. I think slower cooling will give
bigger crystals. Certainly explains why dolomite works.

The gold flecks are pyroxene crystals, better known as teadust crystals.
Ian Currie has a nice discussion about what's going on in his book
_Stoneware Glazes_. As with other crystalline glazes, pyroxene crystals are
encouraged in low alumina glazes. The make up of the crystals can vary
quite a bit, but usually contain CaO and MgO along with SiO2. There might
be some iron and alumina in there as well. Currie says that pyroxene
crystals will form in a variety calcium glazes, including copper reds as
long as the glaze is reasonably low in alumina and there is some magnesium.
Slow cooling helps also. Currie suggests a series of experiments for both
iron glazes and pyroxene crystal glazes. I've done three of the iron
experiments and gotten some very nice teadust effects over a range of iron
glazes, from honey to temmoku. What's really interesting is to see the size
and number of the crystals vary with the alumina and silica content of the
glaze. Generally speaking, there will be more crystals as you increase the
silica in a low alumina glaze, and there will be fewer crystals as you
increase the alumina and keep the silica constant. The firing schedule has
a big impact on these glazes. You can lose the whole effect with a fast
firing and quick cool.

From what I'm recalling of this thread, the glazes are high-fired---has
anyone usedd this technique (either dolomite, MgO, rutile, etc) with ^6
glazes. I have a great very dark glassy brown, called Temmoku, that I could
try it on---so why am I asking---I'll just go ahead and try it, right? I'll
let you know.
