Oxalic Acid

Post by NikonUser »

I recently received an Olympus KPA polarizing attachment, but no wave plate.
First use was with salicylic and lactic acids, gave a slightly off-colour B&W image.
Today I evaporated some Oxalic Acid and got the pretty colours I was hoping for.
Oxalic acid is poisonous but is found in many plants including tea and rhubarb. Apparently can play havoc with one's kidneys.

Quote – Holmes on ‘Entomology’
” I suppose you are an entomologist ? “
” Not quite so ambitious as that, sir. I should like to put my eyes on the individual entitled to that name.
No man can be truly called an entomologist,
sir; the subject is too vast for any single human intelligence to grasp.”
