I think it may be misleading to make a general statement about "coating
a colloid on glass," since gelatin is often recommended, by those who
do a lot of gum printing on glass, as a sub for the gum coat. In other
words, I get the impression that gelatin must be a lot easier to coat
on glass than gum is. But at any rate, all the above sounds like more
work than this project is worth to me.
