<p>A processing method for preventing the inorganic non-metal from cracking or being broken includes that a metal reinforcing ring which is in the form of a closed loop is provided on the outside of the portion which is easily cracked by the heating. At the normal temperature, the inner dimension of the metal reinforcing ring is smaller than the periphery dimension of the reinforced portion of the non-metal. The said metal reinforcing ring is heated and then sleeved on the non-metal under the condition of high temperature. The metal reinforcing ring supplies a reinforce for the reinforced portion of the nonmetal on the principle of "expand with heat and contract with cold", and forms a integral structure with the non-metal. The vessels such as pot, bowl and cooking pan which are processed by the above mentioned method are also disclosed.</p> |
