Lead-free alternatives to Nigerian traditional glazes

Over the years, Nigerian potters have used lead-based formulations due to their low melting temperature, excellent luster, and vibrant colors. However, the health and environmental hazards associated with lead have necessitated exploration of safer alternatives. In this paper, the development of lead-free alternatives to traditional Nigerian ceramic glazes was investigated. It looks into various lead-free flux materials like boron, alkaline, and zinc-based compounds, analyzing their potential as substitutes through experimental methodology. It was discovered that borosilicate formulations show particular promise in replicating the desirable properties of traditional lead glazes while maintainning traditional integrity and artistic expression. Sustainable ceramic practices in Nigeria and practical guidance for cottage potters transitioning to safer glaze technologies are the gains of this pilot experimentation, as reported.
