I got a chance to do some "pickup" after the closing of a manufacturing
plant locally. Found some industrial plastic material, green in color, one
inch thick. Any idea what it might be?

It could be any of dozens of plastics. PVC, polypropoline, nylon, etc
etc. Some standard simple tests are to see if it melts (and what temp),
see how/if it burns (SMALL sample), see how it cuts. I've found that the
usefulness to a hobbist is determined by how well it cuts. If you can
bandsaw it cleanly, that is good. If you can machine it without gumming
up, that is a plus. I have some 1" polypropoline that is just a pain to
work with.

If you submerge it in water (and eliminate any bubbles clinging to
it), does it float or sink?
If you burn a thin section, what does it smell like?
Does the flame keep burning or stop by itself?
What color is the flame and does it drip?
Is there soot?

If it floats, then it is probably a witch, procede to the next step.
If it smells like a witch be prepared to explain just exactly how you what a
burning witch smells like.
This helps because the degree of evil the witch has obtained the bore they
resist burning. If they spontaniusly combust by tying them to the stake,
then they are in fact not a witch but a pure demon, if they do not burn at
all no matter how hot the fire, then they are innocent and you are in a big
heap of trouble.
This helps those who witness the trial be firm in their faith and allows
them to to postulate the degree of the wiche's guilt.
If so, you may gather the soot and use it to prove global warming is going
to destroy the planet, and that George Bush should have never been on the
ballot in Florida or Ohio as neither state should have been admitted to the
union, it is only a plot of the tri-lateral comission and a zionist
conspriacy.

My first thought was "What does a burning witch smell like?" then I decided
that she must smell like a duck burning in the oven.....

Well ventilated area, blowing away from you, use your hand to bring a
very small sample of the vapor to your nose- just enough to get a
whiff of it. Common sense, eh?

Well, a friend came by today, took one look (and feel) and declared it to be
UHMW. Since it came from a ceramics plant, that would make sense. Thanks
for all the suggestions. I really wanted to burn some but now I don't have
an excuse. All I have to do now is figure out what to do with the slippery
stuff. I haven't determined its value yet.

Sorry Ron, I posted the wrong letters (old age?) and actually *meant*
UHMW (Ultra High Molecular Weight) when I typed it. I get the stuff
from McMaster (usually in rounds) for making some bushings, etc. I
also have made some really indestructible mallets with it as you can
beat on metal objects as hard as you need to without hurting the metal
and not destroying the mallet. Little stringy on the lathe, but it
cuts nice with sharp tooling. Peck drilling works. Have fun with it...
picture frames, cutting boards in the kitchen, etc.
Ken.
Fences and other sliding components for jigs and fixtures, good for
proofing parts (like machinable wax), rack to hold cutters without
dulling or damaging, etc.
Bushings are the most obvious. I use the stuff all the time.
There's a real good chance that it is UHMW as your friend suggested.
Take a knife and shave a sliver off and light it. If it smells like a
burning candle then it is PE and most likely UHMW-PE.
