For some reason, the end-of-day terminology has always bothered me. Partly because there are conflicting or obscure definitions of it, and partly because what do we know what the glassworkers were doing at the end of a long, hot, tiresome day? Sticking around to make another marble, or blowing out of the door to go home? How do we know what some call end-of-day are not just end-of-cane?
At any rate, I don`t think the term clarifies anything, so I personally don`t use it. Just my own decision, of course. All are free to also make their own decisions!
