bubbles. The maximum foam volumes obtained by shaking are also rather lower than
that in the other two methods. The flow chart of the process is as given in Figure 5. 1.

5.2. FOAM CHARACTERISTICS

The most desirable characteristics of a foam honey comb is that it should consist of a
large number of small and uniform bubbles which should retain their honeycomb struc-
ture during drying. Foam bubbles usually burst because of air and thus surface energy of
the resulting drops is smaller than that of the original system. Adequate amounts of sta-
