Refractories are the main building materials for glass furnaces. It has a
decisive impact on the quality of glass, energy consumption and the cost. The
development of glass melting technology mainly depends on the development and
quality of refractories.

Sidewall and bottom of melter predominately consist of fused cast AZS block,
whereas sintered zirconia mullite brick in some cases can be applied to bottom
area, where the application condition is not that demanding. Beneath the fused
cast AZS lie the chamotte block at the very bottom, in between AZS ramming mix
is filled. In corner area fused cast AZS with Void Free Casting is used
exclusively. Fused cast AZS is so far the primary refractory brick for glass
furnace.

In tin bath, alumina forming brick such as sillimanite and bottom block are used
typically.

Silica brick is used also quite frequently in glass furnace. It finds its
application for melter crown, front wall, breast wall and gable as well. It is
the traditional choice for the crown.

?-? Fused cast alumina block is used extensively for breast wall, as well as
sidewall and bottom of cooling zone. Fused cast ?-?alumina block and Fused cast
?alumina block are also used in the crown and superstructure.
