Not steam era but to show the sue of hopper cars.....

The bottle producing plant next to the Coors brewery in Golden CO
gets about 6 hopper cars of "cullet" a week. Don't know where it
comes from but it is shipped in NS conventional open top coal hoppers.

Cullet was also shipped from Oneonta in specal service fishbelly twin
hoppers painted blue.

I don't know about the 1940s, but I remember seeing a photo article

in

Popular Science sometime in the early 1950s depicting a cullet

plant, in California

I believe, showing how the stuff was crushed, metals removed, and

then the

glass was washed and tumbled to remove sharp edges, picked over by

hand to remove

any foreign objects the magnets had missed, and finally loaded into

hopper

cars or trucks.

I suspect that any coloring agents would have been removed when the

cullet

was melted in the furnaces, much as carbon and trace additives are

removed when

scrap iron and steel are melted...the additives unite with the

limestone to

form slag, which is removed, thus leaving pure iron.
