Two - Progression and Adaption

16.08.13 - Day 0

Making the base of Groups A-D end up looking like this (0% rust coverage). Spraying and observations commence for Groups C and D, Groups A and B still being assembled.

19.08.13 - Day 3
Group C:

Observations: Significant rust progression on Group C after one spray. Closer inspection shows a dotted pattern, this may be due to the spaced-nature of the spraying or due to the composition of the nail itself.

Group D

Observations: Almost no difference seen visibly. However close inspection shows just the tiniest of rust formations (approx. 2% total coverage).

22.08.13 - Day 6

Day 6 witnesses the end of observations for Group C and D, along with its dismantling. Preparations complete for Group A and B, observations start.

Group C:

Note: Pictures were taken after dismantling

Observations: Even more rust progression when compared to Day 3. Day 6 shows roughly 90% rust coverage on Group C's nails.

Group D: Noticeable rust coverage on nails with distilled water, approx 5% rust progression. Almost no difference when weighed on scales. 

Groups with electrolysis - after attempts to ensure the circuit was secure (light bulb on), observations commenced.

Group A:

Observations: Sticky tape used to ensure complete circuit (proved difficult). Group A done perfectly in accordance to concepts. Currently 0% rust progression.

Group B: 

Note: Second group of alligator clips from Group A above connect to this, to lessen the amount of power supplies used. So if the top circuit is broken Group B will not work either.
Observations: Minor rusting evident in Group B, almost the same results as Group D without electrolysis.

Adaptations: Frequent breaks in circuit lead to using hairclips/pegs to put a tighter grip on the metal coiled around the nails.

26.08.13 - Day 10

Day 10 witnessed the end of observations for Groups A and B, and addition to its dismantling.

Group A:

Note: Pictures were taken after dismantling
Observations: A significant amount of rust progression (25% rust coverage) for nails sprayed by saline solution. Electrolysis appears to have done little to prevent it, however it may also be due to the periods when the circuit broke that the corrosion may have occurred. Rust minimisation is evident. 

Group B:

Observations: Less rust progression (5% when compared to distilled water on nails without any corrosion prevention measures (Group D), which is an anomaly.
