"In a recent survey of the refractory field particularly regarding high iron and high alkali diaspore it was suggested that perhaps some of these impure clays had the proper flux content to make them a body of stable volume in the initial firing operation. At present there is an apparant [sic] lack of information regarding the commercial value of these impure diaspores. One of the great problems in the use of diaspore refractories is the lack of stability of volume while in service subjected to severe heat treatments of varying degrees" – p. [3].
