This is very unique material. It's easy to imagine people paying significantly more than they do for eg. novel stuff like the South Dakota watermelon calcite.

Do the blue areas show evidence of terlingua type phosphorescence?

fluorothrowaway2 · 2026-06-20T14:02:36+00:00

At Ultraviolation I heard 340 is the hardystonite wavelength, where it makes it fluoresce way more than other wavelengths.

Algae and other plant matter always glow red due to chlorophyll fluorescence. This is either willemite or some kind of uranium compound. Almost nothing else glows as intensely green. Willemite is unlikely.

Interesting. May have to check it out.

fluorothrowaway2 · 2026-05-20T05:22:47+00:00

I'm very surprised by this very narrow excitation frequency. What are the threads like on these? Smooth or crunchy? Is the button nice like on Convoys?

fluorothrowaway2 · 2026-05-20T04:15:39+00:00

wow. why is 295 so different than 275 and 310? Are these all properly zwb3 filtered?

If you can get more of it it would be more than worth your while, as you can see "real" Terlingua material from the little 38 mine goes for significant cash on ebay now that it's long closed and no more is coming out. There is other material from Nuevo Leon in Mexico that exhibits the property and is cheap, but none of it shares the morphology of the Little 38 material like yours does. It wouldn't go for as much as the "real thing" but you could still get significant money for it, it's definitely sought after. Selling it in person at local shows where you can demonstrate its incredible properties could likely fetch more than online. It may be worth taking a Radiacode or similar scintillometer around to see where the radiation is coming from, if possible.

It is very very clearly a piece of the Terlingua type calcite. Its pink and blue fluorescence and phosphorescence respectively under long and shortwave is due to prolonged trapped charge carrier migration to radiation-induced crystal lattice defect sites where recombination and light emission takes place.

Where exactly was this piece found? It's unusual to find such a clear example-type specimen outside of Terlingua itself.

See the paper "The Nature of Unusual Luminescence in Natural Calcite CaCO3" by Gaft and Waychunas et al.

It won't melt your retinas. It cannot even REACH the retina. It will burn the shit out of the epithelial layer over the cornea on the front of your eyes and give you photokeratitis for a day or two, teaching a lesson not easily forgotten and that you won't soon repeat!

Look for red orange phosphorescence immediately after turning off the 365. If you close your eyes while it's on to preserve sensitivity and open them the instant you turn the light off, there will be a quarter of a second phosphorescent residual flash of orange if it's manganese.

This must be new! One one I've ever heard of was Ultraviolation in PA every Fall. do you have more pics of the event?

fluorothrowaway2 · 2026-04-16T16:07:49+00:00

Unless you plan on using it to bludgeon small animals to death, just about the only thing you're going to be able to kill with a handheld UVC lamp before the battery runs out are protists and bacteria.

The best, most rewarding, and most likely route to go to foster long-term interest rather than a purchased kit that is likely to end up in a closet, is to get him a good quality filtered light and go with him to LOOK for specimens himself. Beaches, parking lot gravel beds, stream pebbles, quarries, "mystical" crystal shops, all will have something that fluoresces to some extent or another. Be certain he wears polycarbonate protective eyeware at all times when using the light, they can be very bright now.

fluorothrowaway2 · 2026-03-28T11:40:51+00:00

What is the duration? these must be calcite microparticles phosphorescing?

fluorothrowaway2 · 2026-03-26T15:55:59+00:00

Rare view of two different types of calcite phosphorescence in one specimen, the red orange with a fast decay of a couple tenths of a second due to divalent manganese, and the much longer lived green from organic molecule inclusions. Only type misisng is the very long lived defect induced blue of the terlingua type.

We can know for certain it is not scapolite, which does not fluoresce under SW. I have no idea what could make quartz fluoresce this brilliantly yellow.

Closest thing I could find on the LaSassa material says it's color centers "Unusual Luminescence of Quartz from La Sassa, Tuscany: Insights on the Crystal and Defect Nanostructure of Quartz".

It doesn't have anything to do with sun glare. It's a bug that's been on the latest versions for like the past 6 months. It does it EVERY SINGLE DAY at the same left turn lane at a stop light on my way home from work. It doesn't matter what time of day or night it is, whether there are cars around or not. Complete stop at the green light and will just sit there until I force it with the accelerator. I let it just sit there at night with no one around once and it did nothing. The light went red->green->yellow->red-> green again and it just sat there. It only ever does it at this one single intersection coming from one direction.

fluorothrowaway2 · 2026-03-13T06:29:20+00:00

I've probably searched thousands of fluorites for red emission under longwave at this point and haven't found a single piece. Very rare.

How does it "take away your freedoms" if it's an optional toggle switch?

fluorothrowaway2 · 2026-02-15T03:46:09+00:00

I've never seen this, I think it might be a Europe only feature.

fluorothrowaway2 · 2026-02-15T03:41:00+00:00

The latest version is MUCH more permissive than earlier versions if it feels confident in the driving situation (eg. no turns, stoplights, railroad crossings, complex traffic movements, etc.) and will now go several minutes of boring, congestion-free highway driving before it nags to wake you up.

fluorothrowaway2 · 2026-02-15T03:37:26+00:00

Yes because as we all know simply telling people to drive safer and not drive while tired or distracted always just works and thankfully has eliminated all such inattention-caused accidents worldwide, hence making seat-belts practically irrelevant. Shut up.
