16.  Pottali paka should be done only on
Mandagni (i.e, @135 o
C) in Vidruta
Gandhaka as advocated by Acharyas.
 Pottali becomes stony hard with
characteristic metalic sound
 Monitoring of Agni with a thermometer
timely from 120o
C to 150o
C is a must to attain
correct paka and loss of dravya due to
excess heat

17.  During paka ingredients are saturated with
druta gandhaka.
 This helps in increase in shelf life
 After consumption as it is less soluble and
absorbs gradually after ingestion, increases
the safety of the drug.
 Though during preparation Rasa is used, no
traces of Rasa(free mercury) are found in
finished product.This suggests that Rasa
acts as only catalyst in the whole process.

18.  The ultimate advantage of Pottali over
conventional Bhasmas is in its ability to
preserve the therapeutic efficacy of
Bhasmas for a long time, with out
compromising on the basic quality
parameters of Bhasma viz., nischandra,
rekhapurna and varitara.

19.  Contrary to popular belief that Bhasmas
have eternal potency, in practice it is
observed that they also tend to degrade,
become toxic if not preserved properly.
Hence the need of pottali kalpana.
 Pottali kalpana should be looked at as
advanced rasashastra (pharmaceutical
technique) to increase the shelf life,
therapeutic effects and safety of Bhasmas.
