    The construction of a gas-fired kiln using low-density bricks composed from mfensi clay for schools
    (2011-12-04) Oteng, Abena Akyeabea
    The acquisition of kilns for firing student’s clay works has been a difficult problem for most Senior High Schools and other users of kilns in the educational sector. The 0.42m³ capacity kiln was designed and built with locally obtainable raw materials, locally composed low-density bricks and mortar, and locally manufactured gas burners rated at160000 joules. This is a solution for schools teaching and learning pottery and ceramics as an elective subject. Institutions whose work and activities require the use of kilns will also find this handy. High pressure regulators were fitted onto the 15kg gas cylinder to enable regulation and delivery of high gas pressure to the burners for combustion. A solution has been found in the business of kilns construction with very efficient heat maintenance properties for firing clay products, giving rise to increase in temperature and even distribution of heat is available in bringing green ware to a point of maturity (bisque) at 1100°C.Mfensi clay mixed with sawdust serves as a very useful ceramic material for the production of low-density bricks for the construction of a gas-fired kiln. Recommendations have been made for the production of locally manufactured gas kilns in Ghanaian schools.
