Just a pinch of salt (or two)
|From:||Jim Elsam <firstname.lastname@example.org>|
1. Potassium ferrocyanide (or hexacyanoferrate II) and its sodium-based
cousin are used in nearly all brands of table salt as "running agents".
Hydrochloric acid is not unknown in the stomach. How come we're not all dead
yet (Okay, so in my case it's hard to tell)?
2. Although it's true that you get brighter trichromes on mercury-fixed
tissue, you can get perfectly good results on formalin-fixed tissue with no
need for mercury- or picric- or iodine- salts. Such practice is pretty much
unheard of in the UK where Masson's trichrome is still performed in dark
