One day of immerrsion test in synthetic cutting oil made no difference on 10 mm square sample dimenssions.
Only funny thing is that the is just very little discoroured. Just about noticeable. I started doubting myself, but then I dropped one little blob of new oil and then the difference is quite clear (but still quite small)
Hard to cattch riveting drama on camera - after all it is just a small piece of materil immersed in oil.
Planning to keep it in oil for few weeks and I really don't expect it to expand. If it does then there is something really wrong with the material, but it feels pretty genuine.
Does this makes any sense?
Real test is ofcourse to make something usefull and test it there.
