Luis, all this may be true, no doubt is true, but I don't see the
relevance. I don't deny the varieties of carbon printing. I speak of the
general effect of gelatine coating on so-called "luminance" in printing.

However, I'm glad you mention ceramics. Photo or not, glazed ceramics
have a glorious "luminosity" that makes anything on paper, tricolor, or
sculptured jello mold, seem dead next to it. I would hesitate to show any
kind of print next to ceramics (although that seems beyond the scope of
the original question).
