The invention is about a sort of one-off ceramic material. Which is easily degraded. It is made of major material degraded easily, binding admixture, the substance to puff, elasticizer, anti-friction material and water. The major material degraded easily is kaolin clay. The binding admixture is the mixture of innocuous organic and inorganic binding admixture. And the substance to puff is one or two of plant fiber, pearlstone and flotaftion bead. The elasticizer is plant fiber or glass fiber. The lubricant can be selected from plant oil, silicon oil, liquid wax, and polyglycol. The composition is proportioned by degratable major material 20-60%, binding admixture 20-35%, expanding agent 4-42%, toughness enhancing agent 5-10%, lubricant 1-3% and water 10-35%. It can be used for lableware, package lining, and flower pot, etc.
