[NHCOLL-L:4574] RE: dyeing forams

[Moore, Simon]

Hi Maggie,
 
I am trying to think of the chemical composition of Foram's - basically
silica?  If they have any Calcium content, then Alizarin dyes should do
the trick, otherwise some general histological counterstain perhaps -
Eosin (tetra-bromo-fluoroscein), Light Green, Methyl or Methylene blue,
Aniline Blue - there are many!  
 

With all good wishes,

Sorry for the cross-posting...

 

Does anybody have experience with dyeing forams?  A local scientist has
recommended food coloring, but I'd like to explore non-organic(?) based
options.  I have read that red food-dye is made from crushed beetle
carapaces, so I can at least recommend that our department not use red
if they do proceed with the food coloring route.

I wonder if India ink would work?

 

Thanks for your input or suggested reading on this topic.
