The exterior of the Stone Slab House was quite simple and looked like a place for storing gardening tools, yet it was a small workshop specifically built by Song Youliang to coax Jiyun into learning pottery when she was a child, tailored to her requirements.
Jiyun looked at the coal piled against the wall and scoffed in her mind.
Using firewood to fire a kiln, in one night's time, let alone porcelain made from kaolin clay, even pottery made from clay couldn't possibly be produced.
However, she had come from a later era and knew that coal could also be used to fire kilns, and it heated up quickly and required less time.
She found a sagger of the right size from the shelf, placed Yuan Yunzhong's cup inside, then built a small egg-shaped kiln with the red bricks inside the Stone Slab House, and began firing the kiln with coal.
Of course, it was impossible for his cup to turn into porcelain, but it could be fired halfway—to become a bisque body.
