Abstract: This study employs an integrated, multi-technique, minimally microinvasive investigation of the material composition, stratigraphy, and technique of the Portrait of Farrokh Gaffari, which was created in 1959 by Qollar-Aqasi, an artist of the Iranian Coffeehouse Painting workshop, thereby closing the element → phase → molecule evidence chain by combining whole-field macroscopic X-ray fluorescence analysis (MA-XRF) with X-ray diffraction (XRD) and micro-Raman, complemented by cross-section microscopy and fiber analysis. MA-XRF resolves two subsurface narratives: Continuous Sr and Ba-K line patterns that expose hidden Persian lettering on a reused shop-sign support (blue ground with white lettering), and an Fe-mapped pentimento masked by Fe-poor overpaint, documenting a localized compositional revision. Mapping and section analysis reveal a zinc-rich gray priming beneath the paint and multi-campaign varnishes. Using Bruker Gamma Filter technology, effective separation of substrate-derived and surface zinc signals was achieved, thereby improving the accuracy of spectral targeting. Raman identifies lithol red (PR49, likely PR49:2) as the principal red and Prussian blue (PB) as the main blue. Ultramarine occurs as deep-blue accents. XRD identifies lithopone (BaSO4+ZnS), zinc oxide (ZnO), and lead chromate (PbCrO4), rationalizing why the red is XRD-silent while whites/yellows are phase-visible. Together, these data resolve a compact, high-saturation palette logic: mixture-greens from PbCrO4 + PB, lithopone-moderated whites and reds, and area-specific combinations (e.g., canopy: PbCrO4 + PB + iron oxide + lithopone; fountains and flowing water: PB + lithopone, flowerbeds/red blossoms: lithol Red (PR49) + carbon black). Fiber microscopy identifies a cotton support assembled from two panels with orthogonal warp orientations. Furthermore, it is worth noting that this painting was executed on a repurposed blue-background-with-white-lettering advertising sign, which is a substrate choice that not only aligns closely with the pragmatic “local material adoption” principle of the Coffeehouse Painting workshop but also echoes their typical painting-on-a-sign practice, with the original sign’s material composition specified as follows: the blue ground comprises CaCO3, BaSO4, and PB, while the white lettering is formulated with BaSO4.

Zástupci Izraele a Hamásu uzavřeli na základě plánu Donalda Trumpa příměří. „Klíčová otázka v momentě, kdy proběhne první fáze, je, kdy začne rekonstrukce Gazy,“ říká ředitelka Herzlova centra izraelských studií na Univerzitě Karlově Irena Kalhousová.

První fáze Trumpova plánu je zásadní. Ukazuje ochotu Izraele a Hamásu dohodnout se, říká Kalhousová
„Ukázalo se, že Donald Trump prostřednictvím svého vlivu jak na izraelského premiéra, ale i na arabské země, má schopnost obě strany donutit, aby dohodu uzavřely,“ říká Irena Kalhousová.

Nifty! Ty

Surface treatments will definitely mess up xrf 😭

Yeah, if you crank up the ma on the xrf you can go deeper, but then you returns get all messed up. I've had to explain that too far too many people 😂

Beautiful torc, for sure!!!!

The Hidden Standard in Chinese Materials Analysis
Skyray XRF Fluorescence Spectrometer A single instrument now governs compliance decisions across China’s manufacturing, recycling, and mining supply chains. The Skyray XRF spectrometer is that gatekeeper. For metallurgists sorting scrap alloys and environmental inspectors screening soil for heavy metals, the bottleneck is the same: time. The Skyray XRF eliminates it. Using energy-dispersive X-ray fluorescence technology and a high-resolution silicon drift detector, it identifies elements from magnesium to uranium in seconds.

(Fragments of) medieval manuscripts were often re-used in bookbindings. MA-XRF scanning can penetrate the bindings without having to take them apart and so make long lost texts legible. One of the finds is a 12th century manuscript containing a text by early 8th-century English scholar Bede.

Out! We wondered what information is retained in the elemental chemistry of an animal poop 💩 that has fossilized - could it be a proxy? 🐊🦖🐢

I sometimes take advantage of the analytical equipment at my real job. This is a Cambrian arthropod (probably not a Beckwithia) from the Wheeler shale of Utah. I used the XRF (X-ray fluorescence) to highlight iron and phosphorus. This is a 500 Ma digestive system.
