Dear
ahmedezat,
(
ahmedezat, - You are missed.)
“
Gooch crucible” as “Platin
um crucible” too, are pieces of laboratory equipments
for “
High Temperature Chemistry” as Reactions, “Incineration”, and so on.
Pictures you may see on:
en.wikipedia.org/wiki/Crucible About “Turbidity of water“:If you paint the inner bottom with an adequate
PIGMENT, you are able to estimate with certain reliability
the turbidity of
“not too strong coloured” water/”waste water”, in case
you have done before a reliable as possible calibration.
It can be a very handy method for “on the field”, as the “
pathlength” of your “
cuvette”
is all times quite well defined (and
?doubled?)!
Good Luck!
