Lithic analysis in African archaeology: Advances and key themes

open access: yesArchaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

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

open access: yesArchaeometry, 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 ...
