If you decide to make other peoples glazes, you must know how to
understand them - in order to have the best out of them.
Please print=20
The limit tables at:
http://www.digitalfire.ab.ca/cermat/education/206.php
To avoid confusing choose the limits Tony has chosen for Insight.
You can print the limits from my site too.
From John's site, his and Ron's limits in their article to the CM
ftp://ftp.frogpondpottery.com/stableglazes.pdf
You can choose any of them for this test.
In Tony's site there is a big article confusing somehow, perhaps, most
of you understand English better than me, will understand it faster.

We, the members of the clayart community using at least partly -the same
glazes.
Many of these glazes can be found at the CeramicsWeb.

The next words are mainly to these of you that when they see computer's
outlet, are skipping to the next recipe.
I am sure you will find some familiar glazes.
I will not deal or hardly with the expansion.
The limits you have printed can help you to decide if a given glaze
might melt properly in the given cone or rang or better to say: In your
kiln.
Difficult?
Give it a try.
Please choose three to five glazes that are working good in your kiln.
Choose one of the limits and compare.
You may have now guiding limits.
Please note in most limits there is not LiO2
But the LiO2 must be consider as a lower of the expansion and as a very
strong flux!
You can add it to you own privet limits!
I would take the Matrix limit graph from my site and draw on it the new
lines.
You can have gloss limits
You can have matte limits.
CTR limits or is in TCR?
Out of several glazes you will write KNO or KNaO from this to that
CaO from here to there
And so on.
Please note to the Si:Al relations telling you if your glaze is gloss
silky or matte.
There are of course exceptional.
MgO rich glaze where the Si:Al is 9:1 still will be mate or silky.
It will be easier to read the new recipes to be tested.
It will not substitute software but to these of you that hardly find
time to raise your heads from the wheels will save some wasting of time
and=85 money.
Talking about money, two out of three programs I have used allowed me to
see the costs! A very important function.
The net suffers all!
When I entered to the net in the first time 9/98 there was a site that
offered glazes with 60-80% lithium carbonate! He leaned on Lana Wilson.
Yes she has a few glazes like that but in that site he had about 20 or
more; a concept. Not every written word should be tested you money your
wares and your heath are in danger!
Because I make a lot of unconventional glazes I have a different look.

If it is too dry remove the alumina hydrate!
I feel I start to be too complicated.
So this is the end of this mission, anyway the spirit of clayart has
returned and we bite no more each other.
