1. Increasing amount of light circles
(decreasing amount of dark circles
100% dark circles
0% light circles
100% light circles
0% dark circles
Phase “a”
Saturated phase “a”
2 dark: 1 light
Saturated phase “b”
2 light: 1 dark
Phases
“a” and “b”
Phase “b”

2. Start with unsaturated, single phase “a”,
Add until “a” becomes saturated.
Add:
Phase “a” – mostly dark circles
Not saturated
Phase “a”
Phase “b”
Saturated phase “a”
(2 dark: 1 light)

3. Now add more a new phase (Phase “b”) begins forming.
Saturated phase “a”
Add:
Saturated phase “a”
(2 dark: 1 light)
Phase “a”
Phase “b”
Saturated phase “b”
The added “light circles” dissolve
some of phase “a” to form phase “b”
(two phases)

4. Now add more until Phase “a” is completely
dissolved and only Phase “b” remains.
Saturated Phase “b”
Phase “a”
Phase “b”

5. One can approach this from “the other side” starting with
Unsaturated Phase “b” and add until Phase “b” becomes
Saturated. Then keep adding to create Phase “a”.
As more are added, Phase “b” becomes dissolved and only
Phase “a” will remain.

6. Phase “a”
Phase “b”
Add
Phase “b” – mostly light circles
not saturated
Saturated phase “b”
2 light: 1 dark

7. Phase “a”
Phase “b”
Add
Saturated phase “b”
2 light: 1 dark
Saturated phase “a”
Saturated phase “b”
The added “dark circles” dissolve
some of phase “b” to form phase “a”
(two phases)

8. Phase “a”
Phase “b”
Saturated Phase “a”
