Notes. In ceramics, Al 2 O 3 comes up when technicians talk about glaze chemistry.It is an oxide mostly contributed by clays, feldspars and frits.As glazes melt oxides are liberated from materials and they form a glass structure. Al 2 O 3 is very important in that structure, mainly imparting stability to the melt and durability to the fired glass. Almost all glazes have significant Al 2 O 3 ...
