บท 426: Dahu's Classmate

Shu Yu wanted to go to the black market to sell things to make money, and the first thing she thought of was glass.

This thing was said to be imported, so its origin would not be very abrupt. Moreover, one could tell at a glance that it was a good thing.

Quartz sand was the most important material for making glass. She had seen it before in Jiangyuan County. She had the raw materials, but the melting point of the Quartz sand was high. It was impossible to reach such a temperature in this day and age. She could only find a way to lower the melting temperature of the Quartz sand.

This required something else.

Shu Yu was busy. Just preparing these things took a day.

This was not enough. She had to find a place to bake it.

Of course, the best was the kiln used to make porcelain. Unfortunately, in Jiangyuan County, such a kiln was controlled by the rich. If she wanted to borrow it, it would be a lot of trouble.
