Firing lightweight Dinas in a tunnel-type kiln

Conclusions The best type of stacking has been ascertained for lightweight dinas on tunnel-type kiln cars.The dinas can be fired in tunnel-type kilns together with ordinary dinas without altering the firing conditions.The lightweight dinas fired in the tunnel-type kilns included the larger types PM-17 and PM-20, so there is no doubt that standard size lightweight dinas can also be fired in these kilns.The satisfactory results of the experiments have enabled the plant to begin firing this dinas in tunnel-type kilns.
