Hidden in the Glaze: Cobalt Blue Decorations of Catalan Tin‐Glazed Ceramics From the 16th to 18th Centuries

Archaeometry, EarlyView.
ABSTRACT This study investigates technological evolution in 16th–18th century Catalan tin glazes and cobalt blue decorations. Analysis reveals three glaze strategies, highlighting shifts in tin oxide use and cobalt pigment composition. In the 16th century, tin oxide acted as an opacifier and cobalt pigments exhibit low arsenic content with CoO/NiO and ...

An Uncommon Instance of Egyptian Blue in the “Pigmented Intonachino” of the Fishpond Wall Painting From the Roman Villa of Torre di Pordenone (Northeast Italy)

Archaeometry, EarlyView.
ABSTRACT The increasingly close integration of analytical techniques in the study of Greek and Roman wall paintings has shown that Egyptian blue was a common pigment, widely documented in the production of blue and greenish hues in ancient painted production.

The Massif Central as a Centre of Roman Brass Production? New Geochemical Data of the So‐Called Hemmoor Buckets

Archaeometry, EarlyView.
ABSTRACT New analytical data of the so‐called Hemmoor buckets, a group of brass vessels from the Roman period of the 2nd to 3rd century ad that are widespread throughout central and eastern Europe, show considerable similarities with the polymetallic Cévennes ore deposits in south‐eastern France in terms of their geochemical characteristics and lead ...

Scientists’ warning on the global destruction of rock outcrop ecosystems

Conservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...
