Development of Clay Bodies for Fragrance-diffusing Ceramics through the Application of Waste Glass and Patterned Seashell Fragments

Abstract

This research aims to develop a ceramic body for the production of scented ceramics using porcelain clay as the primary material, while incorporating waste materials—namely glass cullet and patterned seashells—as additives to reduce production costs and enhance physical properties suitable for fragrance absorption and release. A total of eleven ceramic body formulations were designed and shaped into test specimens, which were subsequently fired at temperatures of 800 and 1200 °C. The physical properties of the fired specimens were evaluated in terms of firing shrinkage and water absorption.

The experimental results indicate that Formulation No. 7, consisting of 90 wt% porcelain clay, 4 wt% glass cullet, and 6 wt% patterned seashells, fired at 800 °C, exhibited the lowest firing shrinkage and the highest water absorption. These characteristics make it the most suitable ceramic body for scented ceramic production. This study demonstrates the potential of utilizing waste materials in the functional development of ceramic bodies and highlights opportunities for further application in creative and sustainable ceramic product design.
