Slightly less than half, 240 or 42% of the 567 film developers and 140 or about 55% of 241 paper developers I have listed have Sodium Carbonate in my very unscientific query. Those numbers are less accurate than they look since there are a few duplicate formulations I have not yet weeded out and a few just plain dubious formulas I have sifted off obscure corners of the net. But I suspect the general tendency for carbonate to be used is very closely mirrored by my numbers.
