More on using Camellia oil

To illustrate the effect of moisture on Camellia oil, I applied the oil to half of a plane blade, then misted the blade with water. Fig.1A shows the initial state of the blade with water on oil (left side), and normal blade (right side). Fig.1B shows the blade after an hour of being left in the open – rust is beginning to form on the RS as the water droplets dry, with some rust also materializing on the LS where the larger droplets have aggregated.


Fig. 1: Effect of moisture on Camellia oil

Fig.1C shows the blade six hours after the initial misting. The un-oiled side shows large rust spots, whilst the oiled side (LS) has rusted forming on near the larger droplets of water. Fig.1D shows the middle portion of the blade – small specks of rust on the LS, larger regions of flash rust on the right, untreated side. This experiment is of course a worser-case-scenario, the normal workshop would by no means have this much moisture (one would hope!). Camellia oil offers a barrier against low levels of moisture, but should not be used as a corrosion protectant in an environment with high moisture content.
