Salut Tony,
here is Smart's comment
" That is the question !!( I wont translate this one)
P't'ête ben que l'ulexite apprécie pas trop les hautes températures de la
porcelaine et que le bore se barre, pffffuitttt !! plus de bore, plus de
fusion."
Maybe ulexite does not appreciate too much the high temperatures of
porcelain and that it disappears, pfffuitttt !! more boron, more fusion.

"Ulexite is the best melting material I know of so I put it
into a porcelain body to replace feldspar. I expected it
to drastically reduce the firing temperature of the porcelain
but it did the opposite. How is this possible. Ulexite melts
to a crystal clearn glass at cone 06, feldspar does not even
do that at cone 10. Then why is feldspar a more effective
body flux?"
