Archaeologist here: This method is very rare to be used by us. It is inaccurate within a few centuries (worse than c14), it is a lot of effort to recover ceramic this way (can not be exposed to sunlight) and if you have some decent pots usually dating by the shape and ornaments is a lot more accurate.

not an archaeologist, but it sounds like this would be more useful for dating brick structures? since it would be unlikely to have been heated a second time and you can grab bricks that were in the back rows not exposed to the sun and with an easily readable depth and exposure? or am i totally off base?

Ahhh finally a subject I am familiar with. This is actually one of the few scientific methods we archaeologists use. Interestingly we can achieve much better estimates (atleast in certain areas and eras) of when a certain piece is to be dated if we use stylistic analysis. Methods like radiometric dating or carbon dating is only really helpful if we need a rough estimate, because a piece cannot be put into context with other founds.

When scientists wanted to cook pot, I didn't think they did it literally.

Sounds very similar to the way Stars are measured; through luminosity, density, spectroscopy and the such- through seeing the makeup of the star to verify whether the star is full of heavy metals or light elements to justify the age of the star through the peaks of said wavelengths being emitted; in similarity to how the scientists calculate the age of the clay pot based on the amount of light being emitted through the release of electrons by the electron traps.

This is amazing if you really think about how this can be used You can use this one process to find out exactly when a group of people started firing clay pottery, a good sign of permanent habitation; but also when the last fire they ever built died out, marking the end of life in a particular area for one reason or another

Interesting thing I haven't heard/done in us it's awesome ❣️ guys

I think that the photo taken by Jongleur100 was taken in a restaurant in Madeira Island, I love that restaurant and its surroundings.

Thermoluminescence is also very commonly used to measure radiation exposure to people who routinely work with ionizing radiation, such as in nuclear power or radiomedicine. It's extremely precise, and it can even be used to differentiate between different types of radiation by using multiple crystals with different isotopes, impurities, and shielding.

Dude, I dig it! I really appreciate it, it's highly informative! Does pressurization ever produce, or effect/alter results at any stage including unearthed? & on another side note, these archeologists seem to me like Forensic Wizards. We're all pretty fortunate for some of the strategic methods they relay. I really need to watch this twice. I was curious about element residues the containers may have been used for? If traces would still be there without the reheat? If reheating could positively effect a reappearance presence even though it wasn't present at the time of conception with &or without a glaze. It just got thinking. Thanks & take care!

Neat!

Can you use this technique for dating lava flows?

what about emperor of space? is that title still available?

Is that also how dosimeters for measuring radioative exposure work?

Archeologist here: Yeah this is expensive, hard to do due to the conditions it needs to be found in, and wholly inefficient when kt comes to dating pottery. Just comparing art styles and crafting methods, as well as which layer in the dig a pot was found in works a lot better, is faster, and most often preferred. Thermoluminescent dating is much more efficient when used to date ancient tools and sites (its a method used by West and South African archeologists studying the paleolithic for example) but its still incredibly fallible as the sample *needs* to be uncontaminated and even then it might need to be cleaned by experts (that means measuring out individual grains of sand, it's not for the faint of heart).

Chikin Nuggits Spectroscopy refers to a wide range of techniques, each with their own uses and limitations. “How many electrons are trapped in the crystal structure of this material?” Isn’t really a question that can be answered by those methods, and its one of a limited set of properties that changes in a relatively predictable pattern with time. The preferred method of dating old stuff with physical measurements tends to be radioisotopic dating, but that doesn’t work here because the time when the mineral itself was formed, and thus new radio isotopes stopped being added, is not relevant to us. So, the method best method available may well be this one, finicky and destructive as it may be.

Very cool, but given that the vast majority of ancient pottery was relatively low fire by wood or similar plant based fuel, I have to wonder why C14 dating wouldn't work as low fired clays tend to be porous and often suck up carbon during the firing process.

Carbon 14 is constantly being created in the atmosphere therefore allowing the levels to be reasonably consistent with some minor fluctuations (that can be corrected) throughout time and most. Life forms being carbon based have a simmilar ratio of carbon isotopes to the atmosphere around them while they are alive, dead things don't really have a way to take in any more carbon so any change in the ratio of the 2 isotopes can be stributed to the decay of carbon 14.
