Re: Amido-Schwartz

Amido-Schwartz is a "chemical branding" procedure used for marking 
amphibians. It is permanent for at least a year. It is applied using a cotton 
swab dipped in a solution of 0.5 % amido Schwartz in 7 percent acetic acid. 
It is used to create a temporary water resistant label or tattoo on frogs and 
salamanders after their mucous secretions are removed.

Can anyone tell me what Amido-Schwartz is? A colleague is trying to stain
fish otoliths but the method does not give much detail on what this stain
