4. MATERIAL MADE
Porcelain is a ceramic
polycrystalline materials with
glass structure more than
10%, with the crystal
structure of phase mullite,
quartz and cristobalite.
PORSELIN

5. CRUCIBLE SHAPES
Crucibles have form like a small bowl.
Crucibles and their covers can
come in high form and low form
shapes and in various sizes, but
rather small, about 10–15 ml
porcelain crucibles are commonly
used for gravimetric chemical
analysis.

6. FUNCTIONS
A crucible can be similarly used to
determine the percentage of ash
contained in an otherwise burnable
sample of material such as coal,
wood, or oil.
In the chemical analysis, crucibles are
used in quantitative gravimetric chemical
analysis (analysis by measuring mass of
an analyte or its derivative).

7. Care the crucible
To take care of the crucibles,
we must clean the crucibles
after using it and if crucible is
still hot, we mustn’t directly
put it into water, because
the sudden temperature
changes can cause the
crucible break.

9. MATERIAL MADE
Materials used as dryer
component is usually silica gel
The materials used to make desiccator was a
thick glass, insulating the bottom and the top
made from porcelain
In laboratory, the most common
desiccators used are made from
heavy glass.

10. Dryer material in
underneath, and a
cover that to removable
in the cold because it is
coated with vaseline.
Desiccator has a shape like a pot.

11. Desiccator is used as a place
to store the samples that
must be free of water, by
drying the solids and the
water vapor in the desiccator
is inhaled by the dryer
materials.
FUNCTION

12. CARE THE CRUCIBLE
To take care desiccator we can
clean it after using it and don’t
leave the desiccator in open
state, meaning when it is finish to
used, the desiccator must be
closed again.
