RE: Cyanotype

Will try this later with a glass rod (don't have time for the following
two weeks).

Cool, Michael.
Did you see any graininess or white spots in the 40% coat? What makes
the
40% coat harder to coat?
Is there any way you could post a jpg of the comparison of dmax of the
three? Or do you have a reflection densitometer to measure the
differences?

It seems you are saying that the only benefit to the 20% 2:1 is speed...
