Well, another instance of not believing what you read comes to our
attention. I read in at least one catalog that the Rives BFK was buffered,
if memory serves it was Daniel Smith (possibly others). I'll check & see
if it's still there.
Of course maybe we don't necessarily believe company info either. (Or
maybe that river in France is full of Perrier water?) What does the pH pen
say? Fact remains that for our cyanotype formula, Rives BFK often does not
print well. It tends to white flecks, too.
Meanwhile, an interesting point -- I've clipped an item from newspaper
that says, "Sulfur dioxide emissions, which cause acid rain, have been
reduced by 2.6 million tons since 1990."
Could it be all that "buffering" will soon be de trop?
