Preforming on leather hard clay of the bottom of a pot to cook soup (dlah pay)

Mai Kim first uses a flat bamboo slice to remove the dlah pay from its support. Then she sits down with the pot on her legs and, with her right hand inside, she slightly pushes the bottom out, using her left hand as a support on the outside. She pushes it to be round, the centre being pushed around 1-2cm away. When it is pushed enough, she puts it upside down on a support or on the floor and smooths the outside with a bamboo stick and water to regularise it and fill the cracks that appeared on the outer surface of the bottom while pushing from the inside. She sometimes spreads some clay that she scraped out to even the surface. Once she is satisfied, she smoothes the whole outer surface with her fingers and water And store the pot on banana leaf on the ground.
