ZIRCAR Ceramics owns and operates nearly 2 dozen kilns. Several are small top loading kilns that are fired to 1300C. By replacing the original IFB lined lids with a stacked blanket (ZIRCAR’s Alumina Type NMB) we have extended the life of the lid significantly, made the kiln more energy efficient and with the simple lift system, made it much easier and safer to use. We will be happy to build this type of kiln lid for you.
