Sounds like a good list, but I note there are no frits
except 3134. Get some 3124, too, and maybe some 3195 if
you want calcium matts. How much of each (as with any
material) will depend on the glazes you want to make of
course/ As for the mexh of silica, the finer the better,
get a better melt - usually 325 mesh. 200 mesh ('clay
grade') will work, but maybe plan to soak longer for best
melt. And if you don't buy calcined kaolin, don't forget
to calcine some yourself. And you may want a little tin
and possibly nickel. And a gerstley-substitute. And bone
ash, and wollastonite. And also some CMC.
But maybe just get small amounts, for testing. Then when
you find glazes you like, order whole bags of the stuff
you'll actually need.

Howdy all:
Man we had a bunch of postings to clay art over the holidays. My delete
key got a major work out.
I plan to get my first stock of glaze ingredients very soon and begin
playing with myself. oops. Anyhoo, I did my archive research and found
a suggested list by our own Paul Lewing for cone 6 glaze ingredients.
Here is MY version below with amounts. I do not yet have Ron and John's
book, so I can only go by Paul's suggestions and those few glazes I have
seen in the short time I have been 'doing' clay.
Suggestions with rationale would be welcome, nay, begged.
Pweeeeeeeeese.
Silica (for glaze, what mesh, what mesh, what mesh!?) 50#

Taylor I would suggest getting at least 1/4# cobalt oxide and you might get a
price break at a whole lb. Its not cheap stuff though. I assume you will be
using your start up chemical inventory for lots of testing so you may not want
to invest in large quantities of anything except for the basics (silica, neph
syn., custar feldspar, epk, etc). How about some Tin Oxide? I've got a few C 6
glazes that call for that.
And there are a few chemicals that I got for "just in case" in small
quantities: Bone Ash, Frit 3124, Strontium Carb, Wallastonite.
What I do when I plan on testing new glazes is get my glaze journal and
record all the glazes I want to test and I leave plenty of space between the glazes
so I can later go back and record my results and have room to do so. Then I
make columns of each chemical I will need for each glaze and record the amount
I will need for the batch size I am making. Then I add up the columns to make
sure I have enough of each chemical or to let me know how much I need to
purchase. There is nothing more frustrating then weighing out ingred. for a glaze
at midnight and then find out you don't have enough cobalt carb (or whatever).
Good luck, and most of all, have fun!
P.S. don't forget the cones!!!!
P.S.S. don't forget Ron and John's book!!!

Hi Taylor,
Just my thoughts on this....
Would it be easier to make the grocery list if you have an idea what you
wanted to make for dinner? :o)
That way, you can be sure to get enough of what you really need, and
postpone purchasing things you may not really need now or ever. Sure,
staples are one thing...i.e. EPK, Silica, etc. Just like milk, bread and
eggs. But when it comes to oxides, carbonates and frits? Well, I'm not sure
I'd buy pickling spice or saffron without knowing that I really needed it.
What I would do is select three or four glazes to start working with, then
make the shopping list based on those recipes.
Best!

Suggest you up your quantity of ball clay to 50# and frit 3134 to 50#
(this will end up being a very important and often used flux for you).

Hi Taylor,
A few things you might want to think about when stocking your larder...
Whenever possible I would suggest buying glaze materials in unopened 50
pound bags.
Picture this, Joe ceramic employee is in the back room weighing out 5 pound
bags of frit. He gets interrupted to
load a half ton of clay in someone's pickup. When he comes back he can't
remember what material he was
working with and mistakenly writes neph sy on the bag. This can cause big
problems in your studio. I've gotten mislabeled bags twice and now I never
buy a repackaged bag unless it is obvious what it is (like mag carb or
copper carb).
And yes, a 50# bag of superpax keeps me supplied for a long time.

the finer mesh, 325

Since materials like whiting, dolomite and talc are so cheap anyway, why not
get 50#?
You are paying a lot for labor for the smaller quantities.

Same for ball clay.
> Bentonite 1#
> Magnesium Carbonate 1#
Unless you want magnesium carb for crawl or bead glazes (in which case you
want more than a pound),
you will have less problems with glazes cracking and falling off while
drying if you sourced your
magnesium with talc and/or dolomite. (Computer programs are great for this
kind of thing.)

Get a pound from one of the places in CM that sells cobalt cheap.

> Chrome Ox 1#

A couple other materials that I use a lot at cone 5 are gerstley/laguna
borate and alberta slip.
Have fun. Glaze materials can be addicting.
The more you get, the cheaper it is.
(I'll take a thousand pounds of this, and 100 pounds of that...)

Hey There,
How fun, getting the glaze room together. So how much glaze will you be mak=
ing all at once? 100 grams?1000 grams, or 5 gallon buckets? First, I'd get =
more Neph Sy, maybe even a 50# bag, you'll use it. Maybe a little more ball=
clay too, like at least 10#-15#. I also like to have frit 3124 around, or=
for high boron, 3195. I don't know if you do functional work or not but if=
your working with cone 6 oxidation and like color for nonfunctional work s=
trontium carb is a must have or if you like the more "dangerous" route bari=
um carb is fun at cone 6. Maybe 5# or so. Soda ash is good to have around, =
maybe 5-10#. Although I remember using a lot of pearl ash in my research an=
d I got some interesting results, but now I'm just getting wierd! I think I=
remember using a 200 mesh silica more often than not, but I'd see what oth=
ers have to say on that. And if ya like crawley glazes get way more Magnesi=
um Carb, those are fun at cone 6 too. Ooh! Ohh! and crystalline glazes too,=
are interesting at cone 6, then you'll need plenty of zinc ox. But I don't=
know if I would attempt those without a computerized kiln that you can pro=
gram, unless you like checking the kiln all the time. Well, have fun! Go cr=
azy!!

Hi Taylor,
200 mesh silica is fine - the 400 is almost the same - the grinding
machinery has become so efficent that it's mostly (like 95%) microfine
(over 400M) anyway.
For cone 6 - as others have said - buy a bag of 3134, EPK, Custer and OM#4.
You can use some wolastonite 10 lb and 10 lb F3124.
If you are going to get our book (and you should) you will also want 10 lb
each of F9195 and F3269.
If you are going to make red glazes you will need some tin.
If you can't make decent glazes with that lot you are in trouble.
Check out the price for the smaller amounts - you will find - in some cases
20 lb of a material will cost about the same - or more than the original
container.
