Greetings!
I am new to ceramics (and this list!) and stuck at a collage where we have
only cone 10 reduction firing.
I am getting into crystalline glazing and testing Laguna cone 10 'Crystal
Palace' base. Has anyone worked with it and can anyone tell me their results
/ experiences? How thick should this glaze be applied? MUST it run?
Peace and Blessings!

I have used the Laguna Crystal Palace cone 5-6 version and found it a
poor product. The instructions did not tell that zinc oxide had to be
added to get the crystal effects. When I called Laguna to find out about
it, I was told about the need for zinc Ox and informed that a new
crystal glaze was soon to come out. Haven't heard if it has hit the
market yet or not.
Crystal Glazes don't have enough silica in them to prevent them from
running. If they did, you would not get the crystallization so sought
after. To accommodate the runniness you must make special bases for the
pottery pieces to be fired upon, then grind the bottoms after firing to
remove the base which will be stuck tight. It's worth the effort though,
for crystal glazes are very striking.
I think you would be better off making your own glazes, and there have
been some articles this last year on crystal glazes in PMI.

Hiya, Rich and all you guys,
I've been using Laguna Crystal Palace Cone 10 for many years,
my results, for the most part are on the website. Normally I
get really good results from it, and I typically fire only to
cone 8.5 or 9. Unfortunately the last batch I got ... well, it just
doesn't work, no matter what temp I fire it to. Alas I didn't keep the
batch number. But so long as you don't have that batch it should
work great!

John - Thanks for the information. I was not aware that additional
zinc needed to be added to the cone 5 Laguna Crystal Palace glaze. No
wonder I was getting crappy results.
I'll stick with making my own from now on.
Bill
william schran on fri 1 nov 02
Fa - What kind of results have you been getting with the cone 5/6
Crystal Palace? The few times I've tested in with batch of my own
cone 6 recipes, the crystal palace has always come out blistered.
Perhaps firing too high.
Been having a blast with a class this semester on crystalline glazes
at cone 6. One thing we have not been able to determine is a good
temperature to raise to from the holding temperature to create halos.
Any thoughts?
Bill

Well, the lab 'tech' at my university OVERFIRED (took it to cone 14!!!) all
our stuff so my first crystal glaze experiment is ruined. Guess I'll try
again. It's just clay right? :o)

Couldn't you do your crystal firings with gas in a saggar? That's how the
early chinese achieved oxidation (or non-reduction) in a wood fired
(reduction) kiln.

Please keep us updated on your results DJ. I suspect this glaze won't
work due to the loss of zinc during reduction. Now, if your firing tech
(man, got to get me one of those!) knows of spots in the kiln that tend to
not get reduced well, those would be the best place to put your glazed
items (with glaze catching devices attached!).

Fara Shimbo on sun 3 nov 02
Hi, Bill,
About CP cone 5 ... I've tried two different firings with the schedule
Laguna sent me and one on a schedule I normally use and the results have
been ... well, they haven't. After a two-hour soak I once got crystals
about 5 mm across. The other two firings I got none whatsoever.
I did get some really nice crystals with Bory 1, oddly enough (it was
on the underside of a test piece).
As for what temperature to hold at, they said to hold at about 1150 but
I think this is way too high. I'm going to try a whole run of Bory 1
and see what happens.
Let me know what's going on with the class,
Fa

Are you sure that was oxidation? A saggar isn't going
to create oxygen from nothing, if it's surrounded by
a reducing atmosphere. Old-style saggars prevented ash
deposition, but can't have modified the atmosphere.
Nowadays we think of saggars as atmosphere-modifiers,
because we use them in reverse, to create reduction
in a non-reducing kiln by packing the saggars with
combustibles. But I don't know of any way to create
an oxidizing atmosphere on an otherwise-reducing kiln.
Any well-designed gas kiln should be capable of firing
in an 'oxidation' atmosphere, though. Reduction is a
choice, not an inevitable outcome of fuel firing.

Fa - I'll post to Clayart a report at the end of the semester how
things went. I know we probably won't go too far from formulas that
have been working previously.

Actually saggars would adversly affect the fire in that it would prevent
quick firing (cooling and heating) by providing more *stuff* for the kiln
to have to heat up quickly. At least with modern crystal fires that is.
I've been very fortunate with the studio space I'm currently using. I am
renting space from one of Bacia's former students: Lotte Streisinger who
has a beautiful studio and a residential gas kiln.
But Ilene... firing the gas kiln, while fun, makes me appreciate the
programmable variety of kiln. Especially in that 12th hour of firing...

I believe you are right there Snail. There may have been a more neutral
atmosphere in those saggars but in truth I'm sure it was protection from ash
deposit. Sorry about the misinformation.
