What is the best ash to burn before preparation?

Marijuana In the firing process, pine ashes are scattered on pottery and glazed at high temperature to form a "linen" texture with white, yellow, blue and other colors. When some works are fired, a large amount of pine ash falls on the vessel and melts into strips, and some glazed ashes on the vessel will form a flowing appearance, which is called "hanging jade" or "flowing hemp" for firing.
