Use of an alumina-rich clay (kaolin) will decrease material cost, because it will require less alumina to produce a proper mullite ratio. If there is too much clay in the mix to dry without cracks or excessive shrinkage, pre-fired mullite grog or a mixture of alumina and silica flour can be added to maintain the composition and reduce the clay content, though this may be expensive to do.
