One of Dala and mine's favorite rare treats is to get a fresh loaf of french bread and dip it in a mix of olive oil, cut up rosemary, and a bit of garlic powder. A bottle of rosemary infused olive oil would be an awesome gift. Thanks for filling me in on the origin behind inconsistent coloring. It makes me wonder if the manufacturer did it that way not only to save money, but also as an artistic touch, because it does give the glass another dimension of character. I know a smidgen about how glass is made, partially from what Dala has told me and partially from a friend of mine who blows glass as a hobby (which apparently is a ton of work and I keep hoping they find a way to make a career of it). Next time I'm at one of the niche bookstores, I'll have to see if they have any books on glass making. Similar to the fake rubies and sapphires, people have been known to take mundane glass pieces and expose them to radiation and various gases (like lead gas) to change their colors and then try and resell them as super rare pieces. It's crooked as shit, but if people are willing to pay literally hundreds of dollars for something like a glass insulator cap, it makes sense that people will try and take advantage of that (kind of goes back to that whole fake trilobyte fossil discussion). However, sometimes you get some really cool, non-crooked shit by creative guys, such as photographic glass.
