As the core equipment for glass production, the kiln is also constantly improving its technical level. It has adopted new technologies such as improving combustion intensity, enhancing heat transfer, reducing heat loss, and reducing pollution to products and the environment.

The technical progress of the kiln requires a variety of high-quality refractory materials as a guarantee.

Refractories used for glass furnaces are required to withstand higher temperatures, sharper temperature changes, stronger chemical attacks, and more severe stress damage. Only with a variety of high-quality refractory materials, the advantages of high efficiency, energy saving, and low pollution of the new kiln technology can be realized.

High-quality refractory materials are not only consumable materials for modern high-temperature technology but also functional materials necessary for achieving high-temperature new technologies.

The refractory bricks used in the glass kiln are AZS and high zirconia bricks, chrome bricks and chrome-containing bricks, alkaline bricks, peridot magnesia bricks, and celsian peridot bricks.

The application of unshaped refractories in glass kilns is also a trend. The ER2SOL series of amorphous materials have been used in some glass kiln pools in Japan.
