ABSTRACT:
In the method for manufacturing a non-sintered quartz ware the quartz and clay are comminuted and fully mixed to make a batch of raw materials. The batch is then added with an effective amount of ore coagulant of which the composition comprises 2CaO.SiO.sub.2, 3CaO.SiO.sub.2 and 3CaO.Al.sub.2 O.sub.3, subsequently, the above components are blended with water and then molded into the desired shape by extrusion pressing. The molded product is then dried under slightly higher than the ambient temperature instead of firing which results in less mechanical strength of the conventional fired ceramic ware.
