Example 2

Test of Resistance to Wax Block Bonding

(14) 100 pieces, in the form of sheets of the same size, of the ceramic resistant to wax block bonding formed in example 1 are selected as group A. 100 pieces, in the form of sheets of the same size, of ordinary ceramic on the market are selected as group B. The ceramics of groups A and B are laid flat at room temperature, then a burning candle is used to drip and harden on the surfaces of the ceramics of groups A and B. Once the molten wax has hardened, it is left for 30 minutes, then the ceramics of groups A and B are positioned vertically for 4 hours, and records are taken.

(15) Results of records: More than half of the wax pieces in group A fall off naturally, and all of the remainder can completely fall off with ease if a simple external force is used, such as light wiping with the hand. The phenomenon of wax pieces falling off naturally did not occur in group B, and the remainder could not be easily removed by using a simple external force such as light wiping with the hand; complete removal was only possible by wiping with the aid of hot water.

(16) The results above show that a glaze surface layer resistant to wax block bonding is formed on the surface of the ceramic resistant to wax block bonding that is produced in the present disclosure, thereby effectively solving the problem of the difficulty of removal of molten wax from the burning of candles which has dripped down and hardened on the surface of ceramic.

In the technical field of the present disclosure, a variety of alterations could be made within the scope of the main technical idea thereof, as long as one has a grasp of general knowledge.
