Dear Heloisa:

I tried a couple of weeks ago to reach you directly in Sao Paulo. No way=
to
get through. The Helen Bates (thank you, Helen) tried, also no luck. I=20
treid again just now, but,
again, the message was rejected. As I read you just now on ClayArt I hop=
e
you can access this post.


Here are three recipes for c.5. 6.

All based on US recipes I know work. These recipes used Ferro
Frits. I adapted them to use your two frits. I "found" that in two
cases my recipe adaptation resulted in just about (mais ou menos) an equa=
l
amount of each frit.

I would test them and then add some opacifiers--maybe a little rutile as
well as opacifier....The first two are based on glazes that had titanium,
rutile, tin, or zirconium added. All were figured on my GlazeMaster=99
program.

I would be very grateful if you tested these and let me know how they tur=
n
out. Many thanks. NOTHING is as exciting as the international characte=
r
of pottery...

Dear Lili,

Thank you so much for the recipes. I look forward to trying them the next
weeks and I will get back to you with the results.
I am trying to reach Ferro and ask about a high boron frit. n/'/tf
I also had no luck reaching you (my emails also returned). I will try and
find out what is happening with my server and how I can reach you directly
next time.
I don't feel I can thank you enough!

All the best,
