My shed is coming next week; I can clear out the garage and get started on
creating my workspace. My nice new second hand kiln arrived last week and
is looking splendid! (18x18x18 frontloading old beast but solid, with ST302
controller. Got it from Corby Kilns - nice people). For the time being I
want to be working with stoneware around the cone 6 - 10 range, only because
that's where I started.
So, as a complete novice, and not getting any tuition until September, I'm
trying to compile a shopping list of glaze chemicals, and I'd really welcome
some feedback before I order half-a-truckload of stuff I'll never use!
Having done some basic checking-out of glaze recipes, it seems that I should
be looking to stock up on the following 'basic materials' (not including any
colouring oxides). My 'preferred' (aka cheapest) supplier is Potclays, and
I suppose I'm looking to buy about 50 or 100kg of 'materials' altogether (in
relevant proportions) - I would really welcome guidance on sensible
quantities, though. I'm trying to save on delivery charges and buy in
economic quantities at the same time (not having a salary any longer is a
major constraint!).
Potash Feldspar
Cornish Stone
Dolomite
Quartz
Flint
Bone Ash
Talc
AT Ball clay
China Clay
{Zirconium Silicate/Oxide
{Tin Oxide
{Titanium Dioxide
Some kind of Borate (Borax frit? GB?)
Is that a reasonable range of materials for a starting point? Is there
anything that I'd really miss not having around if I wanted to experiment
(I'm going to get some barium carbonate and silicon carbide to do some
experiments with - I have recently seen some stunning work at the local
college with barium glazes).
Thanks for any and all input, this is an unaccompanied journey (other than
Clayart, the Internet and books!) into the unknown .....

PS: If anyone in the UK can suggest places to scrounge plastic tubs and the
like, I'd be really grateful - all the local chippies seem to get oil
delivered in plastic bags, not tubs! Bah!

Lewis,
As a relative newcomer to the world of ceramics I stumbled around for =
awhile using glaze formulas obtained from several sources with only =
minimal success. I tried varying proportions, substituting components, =
and even concocting my own formulas but still didn't get anything like =
what I've seen on other people's pots. I even tried commercially =
prepared glazes. I was getting quite frustrated and even quit making =
pots for a few months.
Then I bought 'Mastering Cone 6 Glazes' by Hesselberth and Roy. Every =
glaze formula I've used from their book has been better than anything I =
had tried before. As a plus, their glazes use only a few commonly =
available and relatively non-toxic materials. Now I am starting to vary =
the proportions and components to see what the effects are.
From this experience what I would suggest is that you limit yourself to =
a few basic materials, learn what they can do for you and then start =
exploring with others. If you start out with too many different =
materials you will be faced with too many choices and I believe you will =
just get confused as I did.=20

Whoa, Lewis, 50-100kg of each glaze chemical and you are a self-described
novice?! Are you thinking of going into production? I am smiing here and no
offense is intended. I think you might want to scale down your quantities
until you are deep into glaze making and you find that you love it. You
might not and the price breaks you saved by buying large amounts will be for
naught and you will have a LOT of supplies you might not want. Personally,
I would start out with 20 kg max of the basics such as flint, china clay,
ball clay, potash feldspar and so on.
As for the fancy stuff like silicon carbide, I would keep that for the
future. (I have a special notebook just for fancy stuff that I plan to get
around to when I get the time.) You might want to rethink the barium due to
health issues. (Spend some time in the Archives regarding barium.) The
blues they make may be lovely but... And if you are firing to cone 6, I
wouldn't bother buying any cornwall stone. It's not all that useful at that
temp.
Do you have any glaze books yet? Have you spent some time in the archives
reading about glazes at your temp? The learning curve is steep but
extremely interesting. Spend some time reading and educating yourself.
If you would like a detailed list of what I ordered my first time out, four
years ago, I could try to dig it out.
Best regards,
Carol

Bert Gibson on fri 27 jun 03
Being new to glazing, I have just been through the situation you ask about.
What I did was to start with John and Roy's book and list all the chemicals
I needed to do thier glazes. Next I searched the archives of Clayart and
found the advice of people throughout the years about materials and
quantities. I then put together my list based on that information. What is
interesting is how close my list was to the one Carol provided. The only
significant difference is that on the frits I bought 50# each and the
Manganese Dioxide I only bought a pound. So from my limited experience, I
don't think you could go to far wrong taking her advice.

Bert - I accidently sent my message with my list of materials without taking
the prices off and putting a message on. I also read John and Ron's book -
it was excellent!!! I even sent Ron a message off the list for specifics on
certain chemical. He was so wonderful - he wrote me back with all the
answers. I live in Alaska and had to make a large order so I was worried
that I ordered to much of each. I'm glad to hear that your list Bert was
similar to mine. I guess I am on the right track.
Earl - I am glad that the glazes worked. I am still waiting on my shipment.
I can't wait to start mixing.
To all - I've been on this list for over a year now and I believe this is
only the third time I have written. You are all wonderful. I learn so much
from you. Thank you all for sharing.
