You guys were so helpful last time I thought I'd give it another shot. I need 
to make up solochrome black calcium indicator and Vogel's says to make it up in 
triethanolamine, but since triethanolamine is a solid I'm confused. I can't 
find instructions on how to make the indicator solution itself anywhere on the 
web. Any clues as to where I should be looking? Thanks.
