Comments on the plans:

This kiln is designed from softfireclay bricks. Its advantage is ability to by easily fired, disadvantage is lost of additional introduction of soda or salt (soda or salt harms the soft brick) and somewhat shorten life span of kiln - about 150 firings (when properly cared for and in case of very good softbrick quality use it can last longer). If the use of soda or salt is desired use plans for hardbrick kiln
