How is it that the carbon does not simply combine with available oxygen at
these temps,
slowly eroding your graphite bricks into CO2 gas?
Bruce "just wondering" Girrell
I do, however, find the neutron moderating qualities useful in my new
plutonium-fired
kiln. Reaches ^10 in about 3 nanoseconds. Still trying to do something about
the
25 million year cool-down, though.
