Hi. I can't add much re glass colors (ever tried to describe colors in glass canning jars--variable from top to bottom in same jar after reconstruction). However, at last I can use data from a 1910 house we rehabbed in Pine Bluff, AR. When we pulled the baseboards on this frame house, we discovered that all the exterior walls had a "layer" of glass 1'-2' deep resting at the bottom of the wall. It was all broken, none had mold seams all the way up to the lip, vessel function varied from medicinal to straight alcohol to personal grooming. The walls had no fireblocks so it made it easy to rewire the house. We realized that the glass had to have been deposited at least while the wall was being sheathed (interior and exterior 1" thick boards). I asked old carpenters, and they said, after giggling about drunken workers, that this was a technique to discourage mice. We did find 2 dessicated mice, but that was out of a total linear run of 300' plus of glassed wall. We recovered most of the glass and now it's in the artifact collections of the Arkansas Archeological Survey. The walls were pumped full of cellulose insulation after we finished wiring, and I can't report on if there were new mice but we did live in the house without problems for 12 years. Bye for now.
