Sand, an important refractory material in founding, significantly influences the properties of the mould and quality of the cast. This work investigates the qualities of sand and clay from Eagle Island (behind Rivers State University of Science and Technology, Port Harcourt, Nigeria). The physical and chemical properties of the sand were examined using sieves, mortar and piston, compaction loading machine, electron meter, ph meter, etc. The test was in accordance with American Foundry Man’s Society specification. Results show the sand and clay to be good for foundry industries.
