Use of Waste Banana Peel Ash in Glaze Making

Abstract

Banana peel waste is a very rich source of alkali oxides used in glaze composition. Today, the importance of concepts such as sustainability, recycling, and upcycling has accelerated research into recycling mineral-rich resources such as banana peel, which is considered waste. The use of this mineral-rich resource in the production of ash glaze in the field of ceramic art and the development of new surface suggestions in ceramic art in this context constitute the basis of the research. In this research, the banana peel wastes obtained from Selçuk University dining hall were dried and thermal gravimetric analysis (TGA) was performed, then the banana peel ash calcined at 1000 °C was analyzed by XRF analyzer on elemental basis between Na-U and oxide semi-quantitatively. Using the binary system, glaze recipes developed at 1200 °C from banana peel ash with potassium, sodium and ulexite additives were prepared and the possibilities of using banana peel ash in glaze were investigated.
 The results of the research show that banana peel ash can be used as the main source for obtaining natural ash glaze, as well as an alternative to alkali oxides in standard transparent glaze composition at 1200 °C.
