Hello Ivor,
thanks for your very kind words.
Smart told me the day after his article was uploaded that he sets the
firing temperature according to the ways used to glaze pots at the
factory where he works as a R&D technologist.
They produced 125,000 high-quality pieces per month:

So, I have already asked him to elaborate more on this point
and add any explanation to his original text, I find that very
intriguing also, but very interesting.
By translating his technological posts, I may end up being a good
technologist (Hehehehe).
Later,

I think the article should be called the surface tension of the raw -
applied glaze, because surface tension for me as far As my playing with
Matrix means how smoothly or unsmooth the fired glaze will flow on the
ware. But if I said it wrong do not start a war!
Both Eduard and Smart are good friends, reliable and do not get panicked
when it is not needed.
This last word for both of you: As the only user of cryolite in Israel
thank you very much about your cryolite article. I will be more careful!

Ivor,
Here's my own observation:
Due to the lack of space, I need to organize my way of glazing. So I always
apply my glaze tests by brushing and spraying, and sometimes by dipping when
the test batch is big enough. My tests are usually on mugs and bowls to be
accurate.
Depending on the glazing method used, the same glaze looks definitely
different. The firings are up to ^8 or ^10 in an electric kiln.
Regards,
Marie Claire
