Clean Soiled Crucibles
This is frequently a difficult task. Whenever possible, try to get badly soiled
crucibles into water as soon as possible (after they have cooled, of course).
We recommend trying our cleaner named “Flinn-It” on page 66. This cleaner
may do the job. Allow the porcelain crucibles with carbon deposits to soak in
this mixture for at least 8 hours. Do not allow this mixture to remain in contact
with glass for more than a few minutes.
The black residue that is sometimes present in a porcelain crucible after
the high-temperature combustion of magnesium experiment is difficult to
remove; however, it will not affect future use of the crucible. The residue is a
nonreactive complex inorganic compound composed of Mg and the elements
found in porcelain (Al and O). Teachers wishing to avoid “dirty” crucibles may
prefer our stainless steel crucibles (Catalog No. AP7615).
