Experimental Example 1

The fairy tale ceramic reproducibility, color score and texture score of the fairy tale ceramics prepared in Examples 1 to 9 were obtained as follows. Fairy tale magnetic reproducibility is the average of the results obtained by repeating three times after arranging 30 ceramic specimens in a completely random batch method. The color score was scored by showing the same sized fairy tale ceramics for 3 minutes randomly to 10 different discriminating agents who had the ability to identify them.

                                  TABLE 1

 Fairy tale     Color score    Texture    Example 1        95%        90       94    Example 2        85%        85       80    Example 3        75%        80       78    Example 4        86%        80       76

 Fairy tale     Color score    Texture    Example 5        80%        83       84    Example 6        78%        78       83    Example 7        83%        75       81    Example 8        82%        68       86    Example 9        82%        65       82

As shown in Table 1, in Example 1, the highest fairy tale ceramic reproducibility was obtained, the color score was also obtained the highest, and the texture score was also the highest.

In other embodiments, Example 1 was optimal because the quality of color was slightly lowered to be used as a method for producing fairy tale pottery by showing relatively low fairy tale porcelain recall.

       As a result, it can be seen that the glaze composition and composition ratio of Example 1 are the most effective methods for producing fairy tale ceramics.

As described above, in the present invention, if the Donghwa ceramics mass production system is provided using the same production technology of Donghwa ceramics as in Example 1, it is possible to easily supply Donghwa ceramics with excellent texture and color as well as Korean traditional ceramics. It is also effective for exporting.
