A porcelain glaze composition containing only harmless components is provided to enable a user to easily adjust surface gloss and smoothness of the porcelain by controlling a mixing time of Potash Feldspar soil containing ferric oxide and apple tree ashes. A method for preparing a porcelain glaze composition comprises the following steps of: gathering Potash Feldspar soil containing ferric oxide and leaving the gathered Potash Feldspar soil as it is to be contacted to air, thereby oxidizing ferric contents; washing the ferric oxide-containing Potash Feldspar soil in a washing step; completely burning apple tree branches and washing the prepared apple tree ashes; and mixing the washed Potash Feldspar soil and apple tree ashes in a ratio of 4 to 1~3. In the washing step, water between 2 and 10 times equivalent to the volume of the gathered Potash Feldspar soil is added to the Potash Feldspar soil, stirred with the Potash Feldspar soil and left as it is in order to remove supernatant. The washing step is repeated 2~5 times. |
