Origin of COE as compatibility measure in studio glass

Henry (you up yet?),

Dan tells me that you guys never talked about COE in the '60s in Madison.

He also sez that he thinks Harvey was (maybe) the first to import the German color bars, but he also never remembers hearing about COE in relation to those.

Where did this COE thing first come into studio glass? Specifically as it relates to compatibility? Any recollection?
