[Lex Computer & Tech Group/LCTG] Mystery I'm trying to figure out

[Ted Kochanski]

Steve,

I  think someone has got it -- you need to isolate the system [put the
stuff in a closed container -- if you want put the  powder in a "teabag"
that you can drop into the "milk" without exposing the system to air  --
ala Lavoisier circa the French Revolution and combustion*1


*1
from wikipedia
Antoine-Laurent de Lavoisier .. also Antoine Lavoisier after the French
Revolution, was a French nobleman and chemist who was central to the
18th-century chemical revolution and who had a large influence on both the
history of chemistry and the history of biology.

It is generally accepted that Lavoisier's great accomplishments in
chemistry stem largely from his changing the science from a qualitative to
a quantitative one. Lavoisier is most noted for his discovery of the role
oxygen plays in combustion. He recognized and named oxygen (1778) and
hydrogen (1783), and opposed phlogiston theory. Lavoisier helped construct
the metric system, wrote the first extensive list of elements, and helped
to reform chemical nomenclature. He predicted the existence of silicon
(1787) and discovered that, although matter may change its form or shape,
its mass always remains the same.
