Thanks, Ian. This is the kind of information I was hoping for.

I plan to mix my own from bulk chemicals (for economy) ... I'm not using Thiourea because I don't want to keep lye around the house.

Do you have any insight about the volume solution of sodium sulfide and its affect on tone?

If you want a warmer tone use Sodium Chloride instead of the Bromide. Or better still use a Thiourea toner for greatest variations in warmth.
