Cerium Oxide works best when there is just enough of it, and it likes
lean conditions. I would suggest most of the issues mentioned with using
this polish are caused by having too rich a mixture of polish. A little
bit goes a long way. Its my favorite polish.

And as mentioned, if you keep your polish clean and uncontaminated, you
can reuse it for quite a while. But remember, the longer you reuse it,
the more contaminents will be included from what you have polished. As
mentioned in MSDS5309 on Cerium Oxide...

This material, if discarded as produced, is not an RCRA "listed"
hazardous waste. However, it should be fully characterized for
toxicity prior to disposal (40 CFR 261). Use resulting in chemical
or physical change or contamination may subject it to regulation
as a hazardous waste. Along with properly characterizing all waste
materials, consult state and local regulations regarding the proper
disposal of this material.

...and...

Container rinsate could be considered a RCRA hazardous waste and
must be disposed of with care and in full compliance with federal,
state and local regulations.

...so you should probably call your local fire deparment (non-emergency)
number and ask about where to properly dispose of your polish. You can
probably run it down the drain (or put it in the trash), but you should
check first.

BTW, the main risk from Cerium Oxide appears to be inhaling or ingesting
it in quantity. Use wet, take reasonable precautions, and clean up after
use. Its pretty safe stuff until contaminated.

 hello
    I am selling my gem collection due to poor health.I facetted and
cabbed for many years and have been selling on Ebay for 2 years.I just
came across a half boulder of what thay call icey-green jadeite which I
bought over forty years ago and I think I paid approx. $600.00 for it
then.My priorities have change in life and I am willing to sell this
piece of jadeite for $300.00US.It was up for auction at one point and
still has the auction markings on it.

For filtering saw oil, I use a scheme similar to the paper bags and chicken-wire, but
maybe a bit easier to construct and manage.  Stack two 4 or 5 gallon buckets, with a lid
on the lower bucket.  (I get used buckets from a local donut shop.)  Cut a large circle
out of the lid, leaving enough around the edge to support the upper bucket.  Then drill
holes through the bottom of the upper bucket and nest two paper grocery bags in it.   Fill
it up with saw sludge and let it sit a few weeks.  Clean oil slowly drains into the lower
bucket and the rock sludge stays in the bag.  This would work with polishing compounds,
too.

Very funny, guys; Paxil sounds great! Tumbling results are starting to
improve and so is my equanimity. Thanks for paper bags and chicken wire.
Another question: if you have only a few rocks to be tumbled, which is
better - lots of filler, or very small tumblers?  I have a gallon size and
1/2 gallon. Thanks again.  Naomi in New York

TODAY'S FUNNY ~

A young man who was also an avid golfer found himself
with a few hours to spare one afternoon. He figured if he
hurried and played very fast, he could get in nine holes
before he had to head home. Just as he was about to tee
off an old gentleman shuffled onto the tee and asked if he
could accompany the young man as he was golfing alone.
Not being able to say no, he allowed the old gent to join him.

To his surprise the old man played fairly quickly. He didn't
hit the ball far, but plodded along consistently and didn't
waste much time. Finally, they reached the 9th fairway and
the young man found himself with a tough shot. There was
a large pine tree right in front of his ball - and directly between
his ball and the green.

After several minutes of debating how to hit the shot the old
man finally said, "You know, when I was your age I'd hit the
ball right over that tree."

With that challenge placed before him, the youngster swung
hard, hit the ball up, right smack into the top of the tree trunk
and it thudded back on the ground not a foot from where it
had originally lay.

The old man offered one more comment, "Of course, when
I was your age that pine tree was only three feet tall."
