The Neolithic Site of Piano dei Cardoni in the Island of Ustica (Italy): Minero‐Petrographic and Chemical Characterization of the Ceramic Finds and Clayey Raw Materials

Geoarchaeology, Volume 41, Issue 2, March/April 2026.
ABSTRACT This paper presents the results of minero‐petrographic and chemical analyses of pottery and potential local raw materials from Ustica, a small volcanic island off the coast of Palermo (Sicily), inhabited during the Middle Neolithic. Typologically, the pottery shows cultural connections to the Bicromica and Serra d'Alto traditions, linking ...

Smelting Conditions and Smelting Products: Experimental Insights into the Development of Iron Bloomery Furnaces

EXARC Journal, 2020
The material record for bloomery furnaces in Iron Age and Roman Britain is fragmentary and, because of this paucity of evidence, the reconstruction of the ceramic structures used in iron production is difficult. Experiments have nevertheless been carried

Circular Alkali‐Activated Cements Based on EAF Slags and Biomass Bottom Ash Using Rice Husk Ash–Derived Sodium Silicate

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
ABSTRACT This study investigates sodium silicate (SS) solutions derived from rice husk ash (RHA) dissolved in 8 M NaOH as sustainable activators for alkali‐activated cements (AACs), compared with commercial SS. AACs were produced using a 50:50 blend of electric arc furnace slag (EAFS) and biomass bottom ash (BA). The effects of NaOH/RHA ratio (6.6–2.8)

Abnormal Expansion Along the Synthesis of Zinc Stannate: A Way for Porous Ceramics Without Addition of Pore Generators

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
The abnormal expansion associated with the simultaneous synthesis and sintering of Zn2SnO4 from ZnO and SnO2 is due to the reaction mechanism and correlated with the conversion. This phenomenon opens the way to manufacture porous ceramics without the addition of pore generators, simplifying the process, and especially the thermal treatment.

Sustainable Mortar Incorporating Treated Eggshell Powder and GGBS: Microstructure and Performance Assessment

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Eggshells contain a thin organic inner membrane that adheres to the CaCO3 crystals, forming a weak interfacial transition zone (ITZ) between the eggshell powder (ESP) and the cement paste, limiting its use as a cement replacement in mortar mixes.
