The thing is, Peerless isn't Peerless anymore. I found some at the hardware store and was really disappointed at how dim and yellow-red they were compared to their reputation. In fact, they were worse than current production cheap Coleman mantles from Walmart. I sent them to a safety lab at the local university and it turns out they weren't radioactive which means they switched to Yttrium instead of the older Thorium formula. After some back and forth on another forum, there's at least two separate product lines appearing under the Peerless name and in identical packaging. There's no way to tell which version you have unless you know who imported them into the US. American Mantle is importing Peerless mantles that are doped in Yttrium and not radioactive. These are duller and redder than the Coleman current production. Some guy named Sam (not joking) is importing different Peerless mantles in the exact same packaging but he's special ordering mantles that are doped in Thorium and therefore radioactive. Unless you have a way to detect radiation, there's no way to know which you have. Supposedly, the Thorium-doped mantles should be whiter and brighter than any Yttrium-doped mantles. However, I've seen some user reports that say this isn't the case anymore. So, I have the following lined up:^^^
Depending on which lantern I’m using I’ve had good results with Peerless mantles.
So, send me all your vintage mantles!Paying attention. I've finally exhausted my supply of mantles I got in Mexico years ago...
My current job is analyzing stuff for elemental content. I know I can do yttrium, not sure about thorium. I can do a library spectrum search and probably figure it out, It's in the lead range of elements. shouldn't be too tough.
Actually, the mostly just came up with reasons it wasn't valid in order to fit their pet theories. A few were pretty appreciative, but far from all.Outstanding analysis, Sir! If you were to copy and paste this over at The Coleman Forum (The Coleman Collectors Forum - CCF - https://www.colemancollectorsforum.com/) you would likely be greeted as a long lost brother, worthy of admiration and showered with kudos and thanks for all eternity - and I mean this honestly!
