摘要： A method of calcining kaolin, comprising the steps of:a) producing a clay slurry comprised of water and kaolin clay of a specific particle size;b) mixing a water insoluble potassium containing glass forming compound into the clay slurry in an amount wherein the potassium content of the slurry is equal to about 1% by weight of the kaolin clay in the slurry;c) removing sufficient water from the slurry to form a material having an extrudable consistency;d) extruding the material into elongated shapes;e) heating the shapes by continuously moving them through a furnace having a zone, wherein the material is exposed to temperatures of at least 2700.degree. C. for at least 30 minutes.
