In late August of 2011, in the course of archaeological excavations of the Ancient town of Mursa, an antique flagon was discovered, evidently well-preserved, with a threefoil mouth and an associated ...handle. The flagon was cast from copper alloy, while portions of the anthropomorphic relief on the handle were further decorated with inlaid and later finished silver. Based on its typology, a comparison with the previously examined analogues flagons, as well as a preliminary analysis of the archaeological layer in which it was found, the flagon can be dated to the end of the first, i.e. the turn of the second century AD.
The flagon is characterized by a wide three-foil mouth, i.e. an opening in the form of a three-leaf clover, a round body and tall handle in the shape of an (unfinished) letter S and decorated with an anthropomorphic high relief. By comparing analogous flagons and relying on previous research of Ancient Mursa, the paper proposes hypotheses on its origin and explains the mythical anthropomorphic depiction from the relief of the handle. A detailed account is given of the procedures of preliminary conservation research and the cleaning trials by which the well-preserved original surface and silver inlays on the relief of the handle were located. The removal of solid and coherent layers of corrosion was performed by way of mechanical cleaning, with all the conservation procedures of cleaning, integration, partial reconstruction and protection of the flagon described in detail.
The paper presents a comprehensive overview of all conservation work performed on the flagon, describing all the procedures and methods used to produce its facsimile. A special emphasis is put on arguing for the proper use of electrolysis in conservation, and also for the disregarded but advisable and often necessary production of high-quality facsimiles of precious and endangered artefacts.
A facsimile of the flagon was made as part of the project through which the Museum of Slavonia wishes to form a collection of facsimiles of its finest artefacts that are to be used in the museum’s education programmes. A facsimile of the flagon body was electrotyped in copper, while the handle was forged by casting the subsequently copper eletroplated tin. This paper presents a comprehensive overview and analysis of all the techniques, especially electrotyping, used for making the facsimile. Although electrotyping is poorly developed in the Croatian conservation practice, it does not mean that it is impossible to make facsimiles of metal artefacts in local laboratories and workshops, by using the very technique of electrotyping that even in today’s world of highly-developed nanotechnologies still represents a method that produces the most faithful copy.
This paper, among other things, attempts to show that even with relatively little technical equipment and with the knowledge of specific conservation methods and electrochemical processes, a superb copy of an artefact can be manufactured, and be rightfully called a facsimile.
U radu se istražuje i predlaže izrada faksimila katastarskog plana Varaždina iz 1860. godine. Opisan je način izrade katastarskog plana Varaždina, koordinatni sustavi, njegov sadržaj, korištenje i ...održavanje te oštećenja plana. Odabirom triju uzoraka koja sadrže sva zamijećena oštećenja istražene su mogućnosti prekrivanja tih oštećenja s neoštećenim dijelovima plana digitalnim metodama. Raspoloživi izvornik za ovo istraživanje je katastarski plan Varaždina u boji kao glavni izvornik, a dodatni su izvornici katastarski plan linijskog sadržaja i terenski katastarski plan, tj. kaširana indikacijska skica. Glavni izvornik i plan linijskog sadržaja skenirani su skenerskim sustavom DeSkan Express za velike formate. Terenski katastarski plan skeniran je stolnim plošnim skanerom formata A3 UMAX Mirage II. U radu za istraživanje digitalne izrade faksimila katastarskog plana Varaždina primijenjen je uređivac rasterskih slika Adobe Photoshop CE 7.0, koji je ponajprije namijenjen za obradu fotografija. Metoda odvajanja boja je odbačena u početku, budući da je karta izrađena ručno. U radu se raspravlja o mogućnosti kopiranja i umetanja nedostajućih dijelova s pomoćnih izvornika, zamjene boje papira bijelom ili nekom drugom bojom, uklanjanje naknadno dodanog sadržaja crvenim tušem i olovkom i drugo. Rasprava se osniva na praktičnim primjerima na digitalnoj slici. Zaključkom se predlažu metode digitalne obrade slike za optimalan rezultat faksimila katastarskog plana Varaždina.

U tekstu se donose rezultati istraživanja provedenih tijekom konzervator-sko-restauratorskih radova na dosad neobjavljenoj kopiji znamenite slike Paola Vero-nesea Otmica Europeiz Duždeve palače u ...Veneciji. Slika se danas čuva u Povijesnom i pomorskom muzeju Hrvatskog primorja u Rijeci, no muzejski inventari bilježe da potječe iz zbirke baruna Georga Hütterotta koja je bila smještena na otoku Sv. Andrije kod Rovinja. Multidisciplinarnost tima kemičara-analitičara, povjesničara umjetnosti i konzervatora-restauratora omogućila je pouzdanije odgovore na pitanja o tehnologiji i vremenu nastanke slike, odnosu kopije prema izvorniku i drugim kopijama iz 18. i 19. stoljeća te optimalan odabir restauratorskih postupaka i materijala.
Zusammenfassung
Thermopapiere werden zum schnellen Ausdruck von Belegen eingesetzt. Sie enthalten ein thermochromes Dreikomponentengemisch aus Leukofarbstoff und einem sauren phenolischen Entwickler, ...eingearbeitet in einen langkettigen Alkohol, das Solvens. Der Entwickler ist wegen der Verkapselung des Leukofarbstoffs im Solvens nicht in der Lage, diesen zu protonieren und damit in seine farbige Form überzuführen. Erst durch Einwirkung von Hitze schmilzt das Solvens, wodurch die Farbreaktion des Entwicklers mit dem Leukofarbstoff ermöglicht wird. In diesem Beitrag werden thermochrome Dreikomponentengemische aus Kristallviolettlacton (CVL) als Leukofarbstoff, Alkylgallat als Entwickler und 1‐Tetradecanol als Solvens vorgestellt, die sich sehr gut dazu eignen, den Einfluss der Löslichkeit vom Entwickler im Solvens in Abhängigkeit der Alkylkettenlängendifferenz ihrer Moleküle auf das thermochrome Verhalten experimentell zu zeigen. Auch der Einfluss hoher bzw. geringer Solvensanteile auf den Farbkontrast wird deutlich. Wir untersuchen, weshalb heißes Wasser Thermopapier schwarz färbt, heißes Öl hingegen keine Farbreaktion auslöst, womit die Thematik um thermochrome Gemische für die Schule in einen interessanten Kontext mit starkem Alltagsbezug gesetzt wird.
Summary
Facsimile paper, so‐called thermal paper, is an example for thermographic recording material which is utilised for fast printing of receipts and tickets. These papers consist of a thermochromic three‐component mixture of a colourless leuco dye and a weak acidic developer mixed with a high melting long‐chain alcohol solvent. The developer is encapsulated in the solvent and therefore not able to protonate the pH‐sensitive leuco dye molecules to build the coloured state of the mixture. A striking colour change occurs upon heating the composition and melting the solvent whereby the developer is free to react with the leuco dye. Thermochromic composites formulated from the colour former Crystal Violet lactone (CVL), an alkyl gallate as developer and 1‐tetradecanol as solvent are presented in this article. The simple contact with hot water leads to colour reaction on thermal paper, whereas no colour change occurs after contact with hot oil. Based on these phenomena on thermal paper, we have found an interesting concept to demonstrate thermochromic behaviour for science education in school.
Zusammenfassung Carlos Montúfar (1780-1816) war ab Quito das dritte ständige Mitglied der amerikanischen Humboldt-Expedition zusammen mit Aimé Bonpland. Das Tagebuch, das er vom 9. Juni bis zum 10. ...September 1802 kurz vor Cajamarca führte, ist von Interesse für Humboldt-Forscher, zumal Bonpland scheinbar keine Zeugnisse weder in Brief- noch in Tagebuchform überlieferte. Recherchen am Original des Montúfar-Tagebuchs ergaben, dass die 1888 veröffentlichte Transkription durch Marcos Jiménez de la Espada aus verschiedenen Gründen problematisch ist. Es muss deshalb ein Desiderat der Humboldt-Forschung sein, eine korrigierte und kommentierte Transkription vorzulegen. Das geschieht hier zusammen mit einer digitalisierten Kopie des Originals.

Resumen Carlos Montúfar (1780-1816) fue, junto con Aimé Bompland, el tercer miembro permanente de la expedición de Humboldt a Suramérica cuando partió de Quito. El diario de Montúfar abarca la porción del viaje entre el 9 de junio y el 10 de septiembre de 1802, hasta justo antes de llegar a Cajamarca. Es de particular interés para los estudios sobre Humboldt, ya que Bompland no parece haber dejado ningún relato sobre la dicha expedición ni en forma de cartas ni de diario. La transcripción del diario de Montúfar publicada en 1888 por Marcos Jiménez de la Espada resulta problemática por diversas razones. Este artículo contribuye a los Estudios Humboldtianos con una transcripción corregida y anotada del diario de Montúfar, junto con una copia digitalizada del original.
