i for one, have always been frustrated with
just the recipe. it almost tells us nothing.
if for certain, clay is the most important aspect
to glaze, then those that promote a certain
glaze idea, should indicate the clay body that
it works with...in concert with (for ivor).
rhodes 32 was made to go on a rich iron body.
without the rich iron, the glaze is total crap.
pasty white, death warmed a bit.
it is like a wonderful chat steve branfman and i
had last weekend.
no matter how many glazes a school or center has,
they want more.
it is like a joke:
`we have 37 glazes, but they want 44.`
most folks don't know how to use even one of those glazes.
or have a clue how to layer, or match the glaze to a clay body.
it so much about new recipes, and not about clay body
and how things work together. not to mention the actual
temp and amount of reduction used in any one kiln. (cone ten
can be many things, to many people, and some folks can make
more smoke than fire and call it light reduction.)
here is a tiny story.
met a nice, hard working couple in ny. they have a gas/electric
kiln. fires to cone 10 in about 5 hours. it works every time.
they use it all the time. it reduces well, good back pressure.
they said.
`we don't think we are getting very good reduction`.
i said.
`what clay and glaze are you using?`
`Bmix and a white clear.`
i said.
`Bmix and a white clear won't show you very much reduction.`
`oh`.
`try firing a copper red, shino or such, then you will know.`
you see, Bmix and a white clear will probably give you white pots.
like steve said....the kids want a new recipe to make their pots
look like steve's. the joke is...he is using the same glaze buckets.
he just knows how to use them.
having just the recipe for a glaze is like saying you are a chef because
you can boil potatoes.
mel
john is not being mean to potters...calling them names.
in fact, no one i know wants better glazes for potters than john.
he just wants folks to understand that more information, and good
science will only lead us to better and better pots. if you want to
share knowledge, give us the entire system, not just the formula.
like this:
bob's bluegill glaze (soft blue)
use with bmix
apply in thin layers no more than a total of six seconds
in the bucket. glaze should be like cream in thickness.
cone 10/over and touching the shelf.
reduction: .06 on the oxyprobe starting at 1800F. hold
the entire firing.
clear the firing, and down fire for two hours at 1900F.
fels 60
whiting 5
ball clay 10
epk 10
dolomite 10
mother earth clay 5 (found under a stump behind
the out house at truck stop 63 near boulder, colorado.
dig only at night when no one else is around...smells funny.)
ground up blue gills 2
mix with bottled water only. we like french water better.
and you will still have just a 50/50 chance that your pots
will look like mine.
if anyone on clayart asks me for more information
about this glaze recipe/and wants to make this, or
needs a map...i will publish your names....but, you
know it will happen.
`mel, i want to make bob's blue gill glaze and i need
a map to get to that outhouse, and how big are the
blue gills suppose to be. or, can we use bass instead?`

In addition to notes for mixing and using glazes, I think all
glaze recipes should include the unity molecular formula.
Of course, one can work backwards from the recipe to
get the formula, but it is better to be supplied with the
glaze author's calculation of the formula.

Mel,
Are the blue gill gutted & washed first?
If you don't wash them, won't they introduce too much flux?
Can you give the analysis of blue gill, in case I want to do my own
calculations and sub a bass?

.
If we want to be more precise and informative when sharing glaze recipes,
why not provide the specific gravity of the glaze rather than saying it
should be "like X in thickness"? Hydrometers are not that expensive, and
certainly less expensive than ruining a bunch of pots or spending time
trying to determine if the glaze is "like cream".

Just remember you are going to have on *heck* of a L.O.I. with either
the bluegills or the bass.
Also, would those be caclined blue gill, or do we need to switch to
Lee's wet measuring method?

I'm with Mel on this. I teach in a community art
center. As a teacher I tell my students how I apply a
particular glaze. And how it should look in the bucket
after it's stirred up. It is up to them to use this
extra information. If someone sees a glaze they'd like
to try, it can be made. Knowing the clay body color
can save the expense and frustration of a bucket of
glaze just sitting there because it looks awful on our
clays.

>Mel,
What is a blue gill? I don't think we have that kind of a bird here
in California. Dp you think a blue jay would work. I don't have the
formula for any of our birds as I never heard of putting them in a
glaze.

Mel,
"i for one, have always been frustrated with

That is why I post many of glazes with the recipe
and a picture

That little "tab" on the training edge of the gill is blue--hence...
And I'm afraid you'll not find many blue jays in Californy--
Stellers jays and scrub jays in profusion,
but a blue jay in CA is... a rara avis!
But I do have good news for ya--my redoubtable

(Edition 5, authors Hammer & Hummer)
says scrub jays will work just fine!

I admit to be a neophyte when it comes to mixing
my own glazes. I've found three recipes I like for
my clay in my kiln with my firing schedule. I am
continuing to test some new ones and tweak my old
ones and trying out various combinations of these
in every firing.
Perhaps it would be great to know all the variables
when people post recipes, but I'm still going to
want to test something to see how it works on my
clay in my kiln with my firing schedule. I'm not
going to program a new firing schedule to test a
glaze (unless it's a knocks-my-socks-off one that
I just have to try).
If I get to the point where someone asks me for one
of my glaze recipes, I'll gladly share all the info
I have for it--the source, what I've done to tweak
it, my clay body, my firing schedule, etc.

after seeing the picture, I think that a scrub jay would give you a
week powder blue, I think that you would need to double the amount of
birds to get a real rich Mother-in-law blue. anyway. how many birds
do you need to substitute for each fish?
now if you used a few Toronto Blue Jays, we Baltimore Orioles fans
might just buy the resultant ware regardless of how it turned out.
