With Thanksgiving a recent memory and December in full swing, many folks have put up a Christmas tree (or a Yule tree, or a Hanukkah bush, or a Solstice shrub, und so weiter und so fort). Of course, those bits of greenery will be decorated as well. We'll deal with the pine greens themselves in an upcoming trivia post. Today I want to focus on the decorations, particularly those of the glass ornamentation persuasion that many people are so fond of.
Your question today: In what country were glass Christmas ornaments first manufactured? (Bonus points if you can point to who started it and in what year). Feel free to submit your answer in the comments!
