As the sea ebbed, the merchant ship ran aground, so the crew boarded the beach one after another. Some crew members also carry cauldrons and firewood, and use a few pieces of "natural soda" as the support of the cauldron to cook on the beach.

After the crew finished eating, the tide began to rise. They were about to pack up their things and go on sailing when someone shouted, "Come and see, there are some glittering and translucent things on the sand at the bottom of the pot!" " "

The crew took these shiny things to the ship to study them carefully. They found some quartz sand and melted natural soda sticking to these shiny things. It turns out that these shiny things are natural soda used to make pot supports when they cook. Under the action of flame, they react chemically with quartz sand on the beach, which is the earliest glass.
