Karl,

Tnks for the reply.  Crystallization could well have
an impact on whether there is or isn't diamagnetism,
I just don't know.  Impurities could well also play
a part...perhaps even as low as .005 parts in a
million.  Of course being as the likely hood of
finding out, could go on forever......we'll leave
that up to others.

Have done and seen enough with carbons problems
with temperature effects, to where, I'll probably
go more into bismuth as the "sandwich" element
of choice.  Although its not the carbon being
floated, it strongly responses to temperature and
that changes the diamagnetism level, with the 
magnet being floated.

Another note; Bob Lamb forwarded me a 1/2 ounce
neo shaped like a tooth.  Was able to float it,
but had to do frequent adjustments to keep it
from contact.  The entire sandwich was carbon.
I also used acouple bar magnets on the side of
the sandwich to eliminate tilting for the most
part.

Bob also forwarded some bismuth.  I used that
for the bottom half, and carbon for the top.
Strange combo but it works.  

................

Some time back someone wanted the internet 
address for Colorado Futurescience, article 
on "Testing the Superconductors", that was
forwarded to PSN.  Seems there is two, one
is a mirror.

http://www.futurescience.com
http://www.websom.com/cfsc/welcome.html

The orginal article of "testing the super
conductors", no longer appears anywhere on
the site.  They sell small superconductor
kits, and go into other "different" subjects.

Thanks,

Meredith Lamb
