Orotone: Seems bit simpler than other alt-processes?

I love the finished products, but even watching the video on the photographers website (towards the bottom of the page), I am still a little unsure how and when the (alternative way to tone) metallic acrylics are used? Just thinking about it, does one just paint the back surface of the glass plate, instead of toning the glass print as one usually would?

He makes pretty much standard gold-toned albumen print, but on a glass plate instead of paper. Then, after he finishes making the positive, he coats the back of the plate with some sort of acrylic paint unlike the real orotones where a gold, brass or copper suspensions or foils are/were used. In that sense, if anything, it would be more difficult than a straight albumen print - having to handle glass plate and make a coating on it, much like the wet-collodion process. So no I wouldn't say this is a simpler than other alternative processes. Cyanotypes would be the simplest and easiest of all, with a single sensitizer and water development.
