All that glitters, experiment 5 a corner of tenth-century europe easy ways to make money online

It’s getting a little silly now to re-summarise the project every time I do one of these easy ways to make money online posts, however far apart they may be, so I’ll invite you to look here for the premise and easy ways to make money online just say where, by december 2015, the project had got up to. In brief, we had started from a belief that we might be easy ways to make money online able to find out about sources of metal for the easy ways to make money online byzantine coinage and how those changed and maybe why by easy ways to make money online analysing them using a technique known as X-ray fluorescence (XRF). We got money to investigate this possibility in april 2015, and either before that or thereafter moved through the following easy ways to make money online developmental steps:

At the former of these presentations we got some pushback easy ways to make money online from the numismatists whose work we were implicitly questioning, which was understandable, but in the latter we got lots of pushback from easy ways to make money online one or two archaeometallurgists who felt that we were not easy ways to make money online people properly trained to do such work and that in easy ways to make money online fact it was pointless, which I saw as one of those ivory-tower problems; people are out there doing such work badly anyway, so would you rather just let them publish it and easy ways to make money online be accepted or shall we aim to do at least easy ways to make money online a bit better? 2 admittedly, we were having trouble doing much better, but that was what we now set about solving…

On 17th december 2015, therefore, three of us brought our test set of coins back easy ways to make money online to the department of chemistry, but this time with a difference. We’d already tried cleaning the coins in acetone, as said, so we had decided that we needed to try harder. But how hard should you try to clean a relatively easy ways to make money online soft precious-metal object of considerable value? Thankfully, this was a question that the team working on the easy ways to make money online staffordshire hoard had already faced, and since I’d been able to talk with one of them earlier easy ways to make money online in the year, we had a kind of answer, which was, berberis (or barberry) thorns: tough enough to shift surface dirt, soft enough not to scratch the metal! 3 so before the test, maria vrij, by now in post succeeding me as interim curator of easy ways to make money online coins at the barber following my move to leeds, had taken the coins and more acetone down to the easy ways to make money online barber’s most suitable room for the purpose and, with the windows wide open, had laboriously worked over their surfaces with thorns under a easy ways to make money online magnifying glass. 4 I can only say that this made me very easy ways to make money online glad to have moved jobs before this could have become easy ways to make money online my task, and I remain very grateful to maria for doing it, but of course the real question was, what difference did it make? And the answer was, sadly, ‘a bit’: the levels of presumably-surface material that shouldn’t really be in the coins (calcium, silicon, potassium, aluminium) dropped, but were not gone.

This was, in many ways, not the answer we wanted, as with so many of the findings thus far. We would much rather not have had to use the easy ways to make money online big, fixed machine to which the coins had to be brought, rather than one of the portable ones we could have easy ways to make money online taken to other collections; we would rather have been able to use a shorter easy ways to make money online test cycle and thus test more things in the time easy ways to make money online we had; we’d rather not have had to clean the coins at easy ways to make money online all; but if we had to clean the coins, we’d rather it had been possible just with a wash easy ways to make money online and a rub in acetone, not with hours of picking at them with thorns with easy ways to make money online your face close over a bath of solvent. If we had (and by we, I really mean maria, sorry maria), to do all that, however, we’d at least have liked it to produce good results. What it actually produced, however, was only measurably less bad results, which was not the exciting scientific conclusion for which we easy ways to make money online might have hoped. But it might be a bit more like actual science, and sadly, it’s a lot more like real life; messy, never quite sorted out, but still interesting…

The former of these papers is now published, in fact, as rebecca darley, “all that glitters…: the byzantine gold solidus, c. 300-1092″, in maria caccamo caltabiano (ed.), XV internationa numismatic congress, taormina 2015: proceedings (rome 2017), II, pp. 982-985. A cite for the latter would be rebecca darley, “what does the science mean? Interpreting metallurgic analysis of byzantine gold coinage”, unpublished paper presented at the british museum/institute of archaeology joint seminar, university college london, 15th december 2015.

2. It seems mean to point fingers, but once it’s being cited it is probably fair game and, on the basis of our experiments, I might raise questions about rasiel suarez, “A metals analysis of silver roman imperial coins using X-ray fluorescence spectroscopy”, online here, whose precision just seems impossible with the equipment he used easy ways to make money online despite his checks (which were not carried out against a standard), and one would like at least to be able to easy ways to make money online ask more questions about the methods and reproducibility of the easy ways to make money online tests in monica baldassarri, gildo de holanda cavalcanti, marco ferretti, astrik gorghinian, emanuela grifoni, stefano legnaioli, giulia lorenzetti, stefano pagnotta, luciano marras, eleonora violano, marco lezzerini and vincenzo palleschi, “X-ray fluorescence analysis of XII–XIV century italian gold coins” in journal of archaeology (2014), pp. 1–6, online here.

Rehren, “A (not so) dangerous method: pxrf vs. EPMA-WDS analyses of copper-based artefacts” in archaeological and anthropological sciences vol. 7 (basel 2015), pp. 387–397, DOI: 10.1007/s12520-014-0198-z, and E. S. Blakelock, “never judge A gold object by its surface analysis: A study of surface phenomena in a selection of gold easy ways to make money online objects from the staffordshire hoard” in archaeometry vol. 58 (chichester 2016), pp. 912–929, DOI: 10.1111/arcm.12209.
