These ingredients are mixed by dry method throughly and after drying they are pressed at 500kg/cm^2 in steel mould and heated at 1000°C in the electric muffle furnace. After cooling they are sprayed with glazes consisting of 30~60 parts of iron-free refined SHIRASU, 30~60 parts of alkaline frit, 10~20 parts of boric acid, 5~10 parts of white kaolin from IRIKI, and 5~10 parts of wollastonite from KIURA. These glazed wall tile bodies are matured at 1160°C in the electric furnace. Physical and thermal properties and bending strength of those wall tiles were investigated. Results are as follows ; apparent specific gravity 2.5~2.6, bulk specific gravity 1.8~4.9, apparent porosity 20~29%, water absorption 10~15%, and bending strength 140~186kg/cm^2.}, pages = {5--8}, title = {シラスの工業的利用に関する研究(第9報) : シラスを原料とする壁タイル(その1)}, volume = {12}, year = {1970} }
