 Yes, I apologize. You will have to make the line, Rubina. Although this talk will be more focused on chemistry than probably she would have given you a much more urbanized view on Geras and the whole project. So I apologize for that in advance. But this is a project we've done together. So Rubina and Akim Liegenberger are the directors of this big excavation in Geras that's been going on since 2011. And we became involved in the Geras studies. So me and Ian Freestone, looking at the chemistry of the Geras, and Hunter Schwarzter have been looking at the typology. And so that way we have kind of tried to cover all angles to try to understand the Geras that came to Geras. Geras, and I really wish Rubina could introduce Geras, but it's at the eastern end of the Roman Empire. And then when the Byzantine Empire is slamming, it becomes either any great part of that. But in 704, there's an earthquake, and that's the end of the city. So that's also the end of the story of the Geras. It's a big temple area. And here are some of the temples. But what they chose to do was to work in one of the more areas away from the temples to look at, hopefully, what they were hoping was the more domestic settings. So not the glass used for the big temples, but maybe the glass used and also in the house. And this is what it looks like. So you may not guess it, but there will be fantastic house structures and beds and things like that, and cisterns for water and all of this. And so here is Jared with the city wall. Looking exactly like the Millennium Falcon. But it actually is actually two hills coming down, and then there's a river, the Barney that runs down in the middle, and it runs through the city gates on either side. And their area, the ones here, the big temple area, this is now all occupied by the city. So there's no access to the ruins on that side. And here's the area with the domestic houses away from the big temples. So a little bit about the stories is there is fine from the stone age, very little from the Hellenistic period, although we find less from this period. And then the city really blossoms in the Byzantine and in the Islamic period until he goes quick, wipes it out. And after that, there's a little bit of settlement in that area from the man looks. One of the contexts that they have, or the most fantastic context they have is when the earthquake hit, there are these houses that are preserved, and they have this house. In particular, they have the most fantastic finds. So not just here at the blast, but also metal and this gold-weed necklace, lots of jewelry, but otherwise, not as rich houses as this one. And this is where we actually right before the earthquake. I'll come back to that because we also find some really interesting glass types in this particular house, whereas we find the more common glass types in the other areas that they have excavated. So they've excavated a lot of trenches within this area. And so what we chose to do was to, actually, Hallberg chose out a selection that would include the most typical of the typology. And it turned out that most of the typology was based on time at early Icelandic, and that's what we did the glass analysis on. And this formed the basis for a very big study that we have then been working on since then. And there's just to show what I couldn't see, that this is a cosmetic flask, so these typologies. OK, so at the time, and I don't have to go through this, but of course, we had the production in Egypt, and we had the production at a different time coast with the different types of glasses coming from the different factories. And so we didn't only want to see what the prominence of the glass was. We also wanted to understand in the workings of the city, so what can we say about the recycling? What can we say about the type of fuels they use because they would all contaminate the glass, it burns through the plate, like we showed for reason a little bit, and also contamination for flow types, pipes and tools. So basically, I understand that. And this seems to be a very big thing. So we did electron microchrome analysis and ICP analysis for the trace element, and here I just want to find out steep, because steep is actually the student who was working on the late context in the lever. So here she's not working on glass, she is actually working on paper glass. The results were that we find, so here are just the different groups from Chabille and Freestone. And what we see is mostly in time of 11 time glasses. We also see Roman glass and a couple of Hellenistic glasses in the selection we had. We can now say from the big selection that this represents really well what it is. There's lots of business time glass. There's also quite a bit of Roman glasses in the Roman context. And then there are some excellent glass types that comes right in the end. And it fits also the stratumizer tools, which we did. We have one here, anti-molar glass from Egypt, and it also had a different stratumizer type of composition, so that was showing that it's from a different stand than the ones along 11 time coast. And we saw lots of signs of recycling. So it seems that Geras really was a talent. Even in the Roman glass, we also see, but this is for the business time glass that was reusing the glass. And I'm about to say that the business time glass is coming from Avalonia, so it has the chemical signature of Avalonia. And we see a very strong correlation between Tegermann phosphorus coming from remelting the glass. We also see that elements that are related to the raw materials in the glass, they had a very low coefficient of variation of glass colorants, so mixed in color glass in the remelting and shows a very big variations within these glass. And we know that there was a lot of recycling for it, because we see in the Artemis temple that under the stairs, there were just these piles of glass, but here they were collecting the glass, taking them back probably to recycling. And this is a photo of this glass from Avalonia, so she's working on that glass. So it's a little bit away from the Northwest quarter that we were working in, but it's just showing that there was a very systematic system where they collected the glass and remeltered it. This is a experimental study by Panger, where she gives, oh, I see that some of the elements are missing, I don't know why, but it's just showing the different contaminants you get in the glass from the different components or from the ash, for instance, this should have said calcium, phosphorus, and potassium. And from the clays, you get alumina, titanium, and iron, and from the blowpipe, of course, iron. And what we see in the Byzantine glass along with the contamination of phosphorus is we also see potassium, but we don't see an increase in calcium. And this seems to be significant for what kind of fuels they were using in their remelting ovens, and that also disappeared. Interesting, it must be a PC, Mac thing, but in Umelge-Mau, there's a study also of these alumina-type Byzantine glasses where they see a build-up of potassium, calcium, and phosphorus, whereas in Geras, we only see a build-up of potassium and phosphorus. So it seems like they were using two different fuels in the two towns when they remeltered the glasses. And this would be a very typical wood fuel, where you have a lot of calcium, wood-ass glass, and we were trying to figure out what this fuel could be where you don't have a build-up of calcium. And so we looked at, since the North West quarter was studied from all angles, Kaniele Magsdorff was looking at the type of animals they had, so we tried to look in these databases for different fuels, or different ash compositions of bone from sheep and goat and pigs and cow, and that actually has a lot of calcium. We also looked at the different trees that everybody had been observed, and so the oak, olive, and pine nut tree will also resolve the contamination of calcium from the fuel ash. But one thing that does not do it is olive pits and pop, so you could take the remnants of your olive oil production, use it as a fuel, that might be what could result in low-protection calcium. And this was kind of a fantastic observation for us, to see that, since we know there are lots of olive presence in gel ash, that they were using a different fuel. So the question is, of course, why did they, we know that they changed the fuel, so it used to be that there was calcium in the contamination from the fuel ash. Is it because they're looking for a cheaper fuel to keep up the man? Is it because they ran out of wood? That is, of course, an open question. But for the newer study we looked at, we actually found some more of the glass types. So in the house that was hit by the earthquake, we see Egypt one glasses, we see plant ash glasses from East, so it seems like there were a lot of trade routes that went open to Gerrit. And the reason we don't see them before the earthquake is maybe Gerrit didn't open up in the business time, or because they were easy to get glass from the 11 coast. Or maybe it's because when they did get them and they broke, they put them back in the recycling piles and then, of course, the signatures disappears. We don't know that, but they are there. There is glass coming from the south and there is glass coming from the east but we can only see it in the context that there's so much problem in the south. So I hope I look up to Kuvina and what she would have said. I know she would have said it differently, but I'm going to... Thank you.
