Dr. Ed that was funny. WalSmart you say!
Bleach would be good for dosing the initial water
inparticular some well waters to reduce the available
fungi, bacteria and other inhabitants prior to
application of dry or liquid materials that may or may
not have microbial seed for starting a colony of bad
bugs. The action of bleach would be short lived.
Biocides as I have stated before are expensive, not
easily or readily available to lay-persons but can be
had with significant looking if one is hard nosed
enough to source out a supplier with lax rules. These
are stabile materials usually and job specific. We
used filtration for water and light with a small
bleach rinse of all materials used through handling
and a 0.2% dosing with biocidal material which
provided shelf life and long term stability.
Personally there are some here who choose to first
state the obvious but need to expand on some things.
My understanding is barium is still used to stop or
reduce scumming in clay body preperatiion. It appears
there are no other substitute for this and we hear
about the toxcity of the material like we do about
chromium and manganese dioxide. Glazes and art
products are certified all day long as well as clays
which includes not only barium in small ammounts but
biocides as well. Its a must have for any company that
is going to stay in business over 3-4 weeks. My
toxicologists (Both) at the time I was manufacturing
recommended my use of biocides even though the water
was being treated and the facilities was being cleaned
and everything was mopped down and wiped down several
times a day with bleach. It goes back to good
house-keeping and good practices.
Ron Roy was totally right when he said to watch out
for the toxic issues with biocides, I wish he would
have also included the long list of others as an
over-all statement. (Most or many material are toxic,
damaging or harmful when mis-used or misunderstood)
Un-diluted and ready for commercial use would be
something you'd watch for and understand and would
have an MSDS as well as product literature and
toxicity breakdown on and proper use instruction. The
same as a clay manufacturer would when adding barium
to clay or using mixing equipment. I would bet they
use NIOSH approved safety mask and perhaps gloves
sometimes. Maybe some don't, I don't know? I'd be
certain to tell them their exposure to toxic
substances was threatening to their health if I
witnessed poor practices such as the hypothetical
above. So Ron did us all a favor by pointng it out
because there are some who will do what you are about
to read at the end of this statement and smile at you
in court. And its time I told Ron thank you for the
reminder. We can all keep reminding each other and
maybe someday we can thank our buddies here for all
the gracious help and extra days we been spared to
come back and haunt the air-waves with more of our
discussions.
Whats not toxic or hazardous in what we do in some
form? It would be easier to ask that than to try to
waddle through the other. Is it safer for a company to
send out glazes for long term shelving or a end user
to have a glaze with bugs in it or a diluted bioactive
agent to stop the bugs. You have to weigh all the
pro's and con's. Do I recommend this practice for the
routine pottery and garage potter, NO! It's not a
common enough problem and its limited and most often
there are other ways to avoid most of this in-situ
with typical potters and potteries.
It admirable to be reminded about toxins and toxic
products. Its good to have other information as well
that helps to mold our behavior around what we do and
make as many changes as we can to protect us first
with the end process also protecting others. There
will never be an end to this discussion, it will
return over and over, and it never should end. Time
changes all things and each year the industry, the
artist and the end user all get better and are more
equipped with information. Except those who eat at
Mickey D's and still try to sue people for getting fat
or those who get burned for drinking HOT coffee
because its supposed to be hot. Those you sorta have
to look long and hard at and think, hmmmmmm. Let it
go, just let it go. Who is going to blame who when it
gets down to the wire?
We have a locker room of top notch minds on this group
and its not limited to one or two. If you read what
each has to say, your almost bound to learn something
very vital to your long term potting potential. Tom
Buck, Dr, Ed, Ron Roy, Ivor Lewis, John H., Kaplan,
John P., Vince, Bonnie, Lili, and so many more who
deserve recogition for what they do. I promise to dig
out the rest over time. They have all been a blessing
and if they ever agree, we are all in deep trouble.
Some come straight from Science and others from the
old school, both styles of people are distinguished
parties that I admire regardless of which end of the
spectrum they gained their training from.

Bill,
Dr. Ed that was funny. WalSmart you say!
"Well, we get lots of information for free from him,
in France they call him "The Library of Alexandria
of Ceramics Technology"
The action of bleach would be short lived.
"Right"
Un-diluted and ready for commercial use would be
something you'd watch for and understand and would
have an MSDS as well as product literature and
toxicity breakdown on and proper use instruction.
"Right on, dilution is the main factor, check Smart's text
for the concentrations to be used. They use them at the
factory where he works and nobody has been intoxicated
yet.
Car driving has killed more people than many other
human activities, and still we drive them."
