I just want to say, I appreciate so much all of your posts. There are some glazes I see and wonder...what do they look like...I read your tests and based on your description and opinion I decide whether to give it a try.
Just wanted to say Thank you :)

Sometimes when I make a glaze test from a recipe, I think, I think I have
tested this before.
I am coming to the conclusion that if I have tested 1000 recipes, I have in
reality only about 300 different recipes. Sigh. But the learning continues.
Just in the last batch I just posted, I found the recipes that were nagging
me.
The Barium Blue is the same, slightly adjusted amounts, of the Turquoise Mat
I have on my site, because
I tested it a few years ago, and use it.
Cartwright Black is a slightly tweaked version of Glossy Black, that was
published in CM Sep. 2005, Jayne Shatz article.
If I had the time and gumption to return to all of my glaze test pages, I
may find a pattern.
I liked what Peter Pinnell said in his last column in Clay Times "As far as
I know" column in the Vol. 12, nr. 5. "There are two rules you'll have to
follow if you want to better understand glazes. You must mix, apply and
fire a lot of different glazes; and the second is that you must pay close
attention to the results"
To get to know materials you have to make a lot of tests.
I think it helps not be hysterical about gram splicing, such as an amount
like 23.3 gr. Try running the recipes through a glaze calc. program after
you round up the percents. You may notice no great change in the formula.
I round up and down to the nearest half gr. because I cannot weight one
third of one 10th. This is not to say to get sloppy, I mean make your recipe
approachable, especially for beginners. All this makes for a lot of good
experience
and good learning.
I just wanted to put that to bed as well, because I thought I saw those
recipes before. So many recipes get slight additions or revisions and
appear with a whole new name. I wish I could remember them all and save
myself some time, but then, I wouldn't have the two test tiles to compare.
That is a big part for me.
