huh?
i converted it. i always prefer to make a 1:1 sol'n of cyano, and a two
cup batch (when mixed) can do a class for at least a day or two. here's
the math:
1 tsp = 5ml
1 tbsp = ~15ml
1 cup = ~250ml

to make Christina's A 1:1 (instead of 2:1), just double the ferric am.
citrate--10tsp instead of 5 in 100ml

then multiply everything to 2.5 (to adjust to one cup water):

A:
10 tsp = 50ml > 50ml * 2.5 = 125ml (1/2 cup) ferric am. citrate
100ml > * 2.5 = 250ml (1 cup) water

B:
1 1/4 tsp = 6.25ml > *2.5 = 15.625ml (just over 1 tablespoon) pot.
ferricyanide
100ml > * 2.5 = 250ml (1 cup) water

that makes sense to me; esp. in terms of the quantities i sense i'm
working with when i'm mixing by weight.

ciao,
