The afternoon continued to be busy.
Another bank was built, also made with red clay into an arc shape.
And then a fire was lit, slowly baking it dry.
Their purpose is to serve as molds for roof tiles.
Without metal tools now, making a mold is not easy.
What if the red clay expands and contracts with heat, distorting in shape, or even cracking?
As long as it's not severe, just pretend it's nothing.
Over twenty pieces of tile clay were finally hardened, inserted into a furnace for firing.
As long as cracks don't appear, it's fine.
During the relatively idle time in between, the two chatted for a while.
Ma Lin described that there is a type of porcelain stone that is better than red clay for pottery-making. Crush the porcelain stone, make it into clay, then shape it into vessels, place it in the fire, and it will turn into beautiful, sturdy porcelain.
Glaze can also be added to the outside of the porcelain, creating colorful patterns.
