PRODUCTION OF REFRACTORY STUDIO KILN SHELVES FROM AFOWA CLAY

Abstract

ABSTRACT

This study investigates production of refractory studio kiln shelves using Afowa clay. In solving firing problems, kiln was the earliest tool used to revolutionalize pottery productions, while shelves are among the furniture inside the kiln where ceramic green/bisque wares are stacked for firing. Most scholars in Nigeria who have written on kiln focused on construction of kiln, little has been done about kiln shelves production. Firing of pottery wares plays important roles in production of earthen or glaze wares. This paper deals with the production of shelves and suggests possible ways it can be used for stocking the kiln. It x-ray the problems associated with cracks on shelves and how to check them. The researcher also elaborates on different methods of propping shelves (bats) in stocking a kiln. Kiln setting for glaze firing follows a general principle of proper foot-cleaning and non-contact. The mechanical and physical properties of the composites are determined. Findings are made to show that there are improvement in hardness value, strength and compressive strength of the developed composites. Also, this research will impact positively on potters and institutions and will further open up research and creative development. It will hopefully discourage further importation of refractory materials and serves as reference material to potters.
