SEM study of black, blue, violet and yellow inglaze colours of the oldest Swiss tin‐opacified stove tiles (c .1450– c .1512, canton Bern)*

Maggetti, Marino

In: Archaeometry, 2020, p. arcm.12638

The ceramic colours of eight late medieval to early Renaissance stove tiles were studied by scanning electron microscopy‐backscattered electron (SEM‐BSE) images and SEM with energy‐dispersive spectroscopy (SEM‐EDS). Microstructural observations and chemical compositions of these colours give some insight into the colouring agents and techniques used by the potters. All decorations...

Archaeometric analyses of european 18th–20th century white earthenware—a review

Maggetti, Marino

In: Minerals, 2018, vol. 8, no. 7, p. 269

This study provides an overview of the few archaeometric analyses of European white earthenwares from England, France, Italy, Slovenia, and Switzerland. White earthenwares were an extremely successful mass-product between ca. 1750 and 1900. They became “the porcelain of the poor man” and replaced the older traditional pottery such as faïence. The invention of this new ceramic type took...

Finding the adequate location scenario after the merger of fire brigades thanks to Multiple Criteria Decision Analysis Methods

Aldabbas, Mohammad ; Venteicher, Francesca ; Gerber, Lenna ; Widmer, Marino

(Internal working papers DIUF ; 18-01)

This paper addresses the issue of selecting a suitable location for a fire station in canton of Fribourg, as a result of a fire brigades’merger, by applying Multiple Criteria Decision Analysis (MCDA) methods. Solving the problem of determining fire station locations through various methods has been analyzed in-­‐depth by researchers. However, a different approach, based on application of...

Phase and compositional analysis of a Sèvres soft paste porcelain plate from 1781, with a review of early porcelain techniques

Maggetti, Marino ; D’Albis, Antoine

In: European Journal of Mineralogy, 2017, p. -

Optical microscopy, X-ray diffraction, X-ray fluorescence and scanning electron microscopy analyses were carried out on a typical Sèvres soft (frit) porcelain plate from 1781 in order to determine the chemical and mineralogical composition as well as the microstructure of its ceramic body, glaze, overglaze decoration and gilding. The body is rich in SiO₂ (73 mass%), CaO (16) and alkali...

The origin of 18th–19th century tin-glazed pottery from Lorraine, France

Maggetti, Marino ; Rosen, J. ; Serneels, Vincent

In: Archaeometry, 2015, vol. 57, no. 3, p. 426–452

Forty-eight tin-glazed ceramic fragments (faiences) from Lorraine, found in excavations or pertaining to objects in collections, were subjected to X-ray fluorescence analysis to determine the bulk, major, minor and trace element compositions. Sixteen superficially clay layers from the surroundings of Lunéville and Saint-Clément were also analysed. The faiences are, with four exceptions, MgO...

Composition and technology of 18th century high magnesia faïences from Fulda

Maggetti, Marino ; Serneels, Vincent ; Stasch, Georg

In: Journal of Archaeological Science: Reports, 2015, vol. 2, p. 40–50

In 1996, archaeological excavations close to the ancient Fulda faïence manufacture site unearthed a rich deposit of faïence wastes (biscuits, faïences, technical ceramics). The manufacture was founded in 1741 by Prince Abbot Amand von Buseck and closed down in 1761. This first archaeometric study of a German faïence manufacture included 31 samples produced between 1742 and 1760. Analytical...

Paul-Louis Cyfflé's (1724-1806) search for porcelain

Maggetti, Marino

In: European Journal of Mineralogy, 2011, vol. 23, no. 6, p. 993-1006

Seven unglazed figurines from private collections, attributed to Cyfflé's Terre de Lorraine manufacture in Lunéville (1766-1780), were subjected to porosity and scanning electron microscopic analyses to determine bulk element compositions and the composition and nature of their constituent phases. One figurine bears the mark CYFFLÉ À. LUNÉVILLE, three the mark TERRE DE LORRAINE. The...
