Here are some frits recipes and links to more frits

This is Remboild&Strick home page.They make frits as well as colorants
(stains, like Mason)
Here are the frits I have or I tried, they might have more I am depend on
the decisions of my supplier.
I take the analysis out of Insight.

This is a great composition. without boron.
It can supply high insoluble sodium.
Here are the details of a frit,
the way I copied from the fax, I got from my supplier at that time, word
by word, than my conclusion, through Insight.

REMARKS
An alkaline frit sepsaly developed to cover a large of applications, frit
3701is slightly soluble, this can be suppressed by addition of our
antycrystalising agent RM484 or by using our frit 5009which is more
stable,
but also higher melting point.
Recommended applications:
*Introduction of Na2O/into glaze formulas
*Binding agent for polishing disks
*Base for underground glaze for reactive flooretile glazes

I wrote them an Email, they never answered.
I entered it into Insight.
Played with the: Na2O / K2O / Li2O 16.6 %
The only way I could do it is by knowing the Atomic weight.
Here is my result, I would like to know your opinion,

You may ask Degussa too- they had a similar frit called 90198.
I add here the low fire majolica I used, based on a recipe from were I learnt:

Because of the high B2O3 crystallize after a few days if you use big amounts.
Hobby Colorobbia is a big brand , in the USA they are called Hobby they do only low
fire glazes, frits and claybody. Their's agent told me they add cobalt to their clay body
to make it bluish white.
