The sum is more than 100% because the SiO2 by gravimetric analysis is not accurate. I think the type used at Fyansford was 32% Al2O3 and 67% SiO2. The bricks were fairly porous -apparent porosity about 35% so were somewhat insulating. <br />Peter BenkendorffProfEngPeterhttps://www.blogger.com/profile/00673665773661963874noreply@blogger.com
