Hello
In the Glaze Chemistry course offered at ECIAD, D'Arcy Margesson
demonstrated the possibility of using a granitic rock both in, and as a
glaze.
I am applying for the Student Study Abroad exchange, hoping to study in
Australia at ANU or UWS. While there I would like to pursue this course
of study with rock local to the area.
If anyone has information on work, past and present, of this nature it
would help me a great deal.
Thank-you!

Niki: Lucky you! the Aussies are doing some great pots in wood and using
local materials. You can do no better than to contact sometimes clayarter
Ian Currie. He is mates with some of the potters that work with local
materials. Steve Harrison - his name comes up again. You also would be wise
to contact our Ivor Lewis.
I had a old Aussie that visited me sometime ago . he gave me his book- Rock
Glazes by Ivan Englund published 1983. the book is pretty heavy reading and
deals with the local glazes of Australia.
Coincidently I have the ball mall grinding away at some local granite as i
type this. Would you please keep me posted of your work with granite?
Have a great time Down Under.
cheers,
Tony

Hi Niki, I've been using granite powder for 10 years as a glaze ingredient.
I use around 28 % granite powder along with other materials of course. Best,
Jim

Hey Jim: does this answer really help anyone? I use 28% granite plus other
materials.
How about this?
I use a refractory coating instead of ITC. the salt kiln at Sheridan fired
30% faster, has shown no wear from salt after 8 firings. I am putting it on
kiln shelves and my gas kiln early next week. here is the formula
2 parts zirconium
plus other materials
hope this helps everyone.
cheers,
Tony

Hey Tony,
How about info on the "other materials" or could this be a trade secret? 2
parts to?
I know the itc competitor made by A.P. Green is 95% Zirconium silicate with
5% binder. I will be testing it in the wood kiln in the spring.
Thank you.

Niki ,
if you can get a copy of "Notes for australian potters " by Ivan
McMeekin
will be of assistance to you . I have put most of his rock
analysis data
into " TMT. " for mat for Insight .
If you go to my digitalfire site you can down load them .
they are listed as pre 1980"s TMT.

I use the powder that comes from cutting marble, often misnamed granite, in
a stonemasons yard.
Just get your sample of local granite, marble etc and have it analysed.
Then put the result in your computer glaze program.
Then break all the "rules" and find something really wonderful!
