·
Pinpoint pale pl light
·
Speckled dull dull white yellow

4- Cut fluorescence((oil shows)) :- Under fluoroscope take some cuttings in porcelains then
add solvent to the cuttings and
describe:
a- Speed B -type
·
Slow streaming ( strmg) poor porosity
·
Medium blooming blomg good porosity
·
Fast
·
instant
C – Intensity D -
color

·
Dull white yellow
·
Bright orange
·
Medium yellow green
5- Natural cut :- Put some dried
stained cutting in test tube, add 2cm of solvent And shake it well then leave it
for( 5-10 minutes ) in normal light describe the color and comparing with
reference color:

·
Very light
yellow Low oil
concentration
·
Light yellow
·
Medium tea
·
Dark tea
·
Coffee High oil
concentration
6- Residual Ring ((oil shows)): - Take the porcelain out of the fluorescence and in normal
light Describe:
