Making my rounds this a.m. after a marathon night studying toxicology and=
metals. ^6 glazes are fast becoming a norm for allot of reasons and artis=
and for me I have dedicated myself exclusively to the study of that heat-=
and am gathering information for a book on the subject.
How do cats come in here? I asked myself that too but I can't help but th=
of those letters about cat litter and then seeing my daughters cat (Who
usually cuts a wide path around me) come into my bedroom where I just pla=
I noticed how involved this cat became when he seen those fish and he wou=

I have also noted on occasion that people say well, "Frits are just so hi=

These materials are leading us to better chemistry through practical mean=

They sell the stuff in tons and train loads to many companies that use th=

because they are consistent and have been fixed with various oxides and o=
materials to meet specified qualities.
We potters are smart. We lost gerstley borate and already have pottery
companies taking it on themselves to provide the replacements where those=
frit companies haven't looked our way. But we also found that they alread=

Here is where I fit in I suppose: I hate anything that isn't simple and e=

years left to do it!
We usually can replace a host of chemical needs with frits only upping ce=

I thought about all that work that was lost among hundreds of tests and o=

The basic 1234 approach is only a drop in the bucket but it is another dr=
that will help fill an otherwise empty bucket. I have contacted my old
reliable laboratory people in regards to testing for me again. They are
approved FDA and use NIST comparisons and also ASTM criteria. Also Alfred=

some friends there.
Have a safe New Year and a progressive one for 2001.
