Don't forget that catechol and pyrogallol give different stain colors. There are times when that makes little difference, but there are times when one color is greatly to be desired over the other, and to be able to choose the desired color without a complete change of development procedure would be a good thing. I don't think Pyro Uno should remain a curiosity. When Sandy is through with its "development" it will be a well documented system as parallel to the Pyrocat series as possible.

I do not wish to compete with anyone. Argue, yes, if it's a civil philosophical argument, but for the purpose of seeking knowledge, not ascendency.
