Hello,
Recently I posted some new recipes and some color oxide arrangements for =
other
formulaes mostly relying on old fashioned calculations methods and out-da=
ted
software left over from my old business.
I must admit my methods have been very effective but I am now getting int=
o the
newer more up-2-date technology thanks to Ron. "Ron you know I like alche=
my
and this new information might turn me into a mad scientist?"
While working with ^10R glazes in the past I have moved down to ^6 Ox gla=
zes
in the last year and have made a good home with the lower firing techniqu=
es
and glaze formulaes.
Alisa has been generous to provide shelves for pots to stick to and for t=
hat I
must apologize. I did test the same glaze my friend and still am using it=
, I
don't know what happened? (Send me a frit analysis of your frit).
The purpose many times for posting a new glaze is to see how well it trav=
els.
I do alot of research and follow-up on the results and replies I get and
record each one in my folders. A prime example was a reduction looking co=
ne 6
oxidation glaze recently tested that was considered great and got many
replies.
I also like to work with the ^6 Reds that are illusive at times and have
mentioned to Lana Wilson that her ^6 red that has always been my favorite=
red
was being re-worked to take out the Gerstley Borate and thus recieved app=
roval
to do so and let her know. (Lana, you will soon recieve the revision). No=
matter what I do to alter it, this glaze was her invention and only my to=
y to
play with.
The opportunity to provide information and share information is vital to =
all
clay workers. Safty and health in our field is gaining new insight and
simplicity is also needed.
I am including a glaze I am working on that seems fixed. I noticed an eas=
y to
make glaze using 50.25.25. mix of ingredients and followed up on adding
additional materials while stretching out the potential for harder glaze =
using
that format to hold the oxide colorants in. Here's the one I wrote that i=
s
easy and yet contains a bit more boron that I normally would like to use.=
It
is setting in white vinegar now after 3 days and not any change in color =
using
2.5% Cobalt ox has affected it at all. Would I still eat off it? I doubt =
that
I would just yet but I am to assume that this one is set to go to the lab=
now
for further research and developement. 4% Copper Carb in one test and 3%
Cobalt in another should tell me something...(This of course would includ=
e the
boron)
Please post anything you will when using this glaze base regarding any ox=
ides
used or testing procedures used when analyzing it for your own personal u=
se.
As always - Do not take this glaze without testing for food service quali=
ty
unless you know it is to be used only on decorative items.
I also have made a matte using this as well with two substitutions for
decorative use. Its still 1.2.3.4. Base but different compounds. More on=
that
latter!!!
Edwards Glossy 1.2.3.4. Base ^6 0x.
Ferro Frit 3134 40.00
Epk Kaolin 30.00
Flint ( Quartz Silica ) 20.00
Wollastonite 10.00
My intent is in helping to move out the old gerstley standards and bring =
in
the newer fritted versions using simple language and chemicals that are m=
ost
easily found while eliminating the use of barium, lithium, and other host=
toxin related materials.
Should anyone need the molecular analysis I have on this I will be happy =
to
supply it and would also appreciate it if Ron Roy would run it through hi=
s set
up. Consider this my News Years 2001 contribution that we all can work on=
and
add to our growing list of newer glazes.
