Since the exact meaning of "Porcelanato Onix Acetinado" is not clear, the following is assumed to be a unique porcelain making process or material to create an ancient text:

In recent times, there is a strange skill called Porcelanato Onix Acetinado. The craftsman makes porcelain, and selects the clay. The quality is delicate and fat, and the color is pure and shiny. First, he heals it with water, kneads it, turns it and pats it to make the soil even. Then the plastic ware, or plate or bottle, has different shapes and is ingenious.

When calcining in the kiln, the control of the heat is crucial. The firewood is different, but the fire is urgent. This method of Porcelanato Onix Acetinado can make the temperature of the kiln rise and fall in an orderly manner. When the porcelain comes out, the glaze is radiant and radiant, as if it were made in heaven. Its surface pattern is like a snake swimming away, or changing like clouds, which is amazing to watch. Craftsmen have studied this technique for generations and kept improving, hoping to pass on this wonderful method to future generations and shine forever.
