******Kodak doesn't make Rapid Selenium Toner in gallons anymore, only quarts, which is expensive. I've been thinking of switching to another manufacturer that sells it in larger quantities.
My questions are:
-Does anyone know about how this chemical is formulated?
-Is there any standardization between the different manufacturers?
If I do switch to another manufacturer I'm afraid my toning times will be wildly different. Thanks very much.

My understanding is that selenium out of solution is not something one should mess with.
Is Kodak brown toner considered a sulphide toner, or is the active ingredient something else? If so, what?

To get round the odor, there are sulfiding thiourea toners that supply sulfide from the thiourea rather than sodium sulfide. Thiourea is alternately known as thiocarbamide.
Hypo-Alum toners also have a lesser odor than the famously smelly sodium sulfide toners. Hypo-alum toners are not the most convenient to use, but do lower the stink.
