Trade Networks and Consumer Practices in Amedeka, Ghana: Negotiating “Nkudzedze” From the Late 19th to Mid‐20th Centuries

American Anthropologist, Volume 127, Issue 4, Page 757-776, December 2025.
ABSTRACT This paper examines local taste practices in the era of “legitimate trade” when the trade in botanical (e.g., palm oil, palm kernel oil, and cocoa) and nonbotanical (e.g., ivory, textiles) commodities replaced the trade in enslaved Africans. Following the 1807 British abolition of the Atlantic trade in enslaved people, the locus of the trade ...

Fabrication of Novel Acid‐Resistant Ceramic With High Abrasion and Flexural Strength Resistance

International Journal of Ceramic Engineering &Science, Volume 7, Issue 6, November 2025.
ABSTRACT In this research, the innovative ceramic production process begins with the drying and grinding of raw materials to a fine powder, which is then sieved and dampened before being shaped into ceramic forms using a stainless‐steel mold. The material is pressed at 400 bars for 15 s to form a 10‐mm‐thick ceramic.

Stain Resistance of Porcelain Stoneware Tiles: The Influence of Microstructure

Key Engineering Materials, 2004
This work deals with the appraisal of the most important microstructural parameters influencing the stain resistance of polished porcelain stoneware tiles. The correlations between the stain resistance on one side and bulk or surface characteristics on the other side were evaluated through a statistical approach, which provided a previsional model of ...

The Use of Ornamental Stone Waste (OSW) as Raw Material for Porcelain Ceramic Tiles Production

International Journal of Ceramic Engineering &Science, Volume 7, Issue 5, September 2025.
ABSTRACT Despite the relevant contribution of the ornamental stone industry to the international economy, the large volume of waste generated during the production process is one of the main problems faced by the sector. Currently, the ceramic industry has shown to be a powerful alternative for the use of these wastes.

Effect of nanosilica and nanoboehmite in the pyroplastic deformation of a porcelain tile paste

International Journal of Applied Ceramic Technology, Volume 22, Issue 5, September/October 2025.
Abstract Porcelain tiles are low‐porosity ceramic coatings, formed by a mixture of clay minerals, quartz, and feldspars, and fired at temperatures close to 1200°C with formation of a liquid phase that can result in unwanted pyroplastic deformations. In addition, the rectangular formats, large dimensions, reduced thicknesses, and fast thermal cycles ...

Investigation of nano‐SiO2 and nano‐Al2O3 additions in glaze formulation for Brazilian polished glazed porcelain stoneware tile

International Journal of Applied Ceramic Technology, Volume 22, Issue 4, July/August 2025.
Abstract The ceramic‐glaze for polished glazed porcelain stoneware tile is directly linked in determining the quality of the final product, as its characteristics significantly influence surface properties after polishing, including stain resistance, abrasion resistance, and chemical resistance.
