In Qin Wan's concept, glass and colored glaze are almost the same, but who knew that the firing process is so different.
Glass materials are simpler and cheaper, and because it does not require color and requires much less minerals, the cost is low.
However, the firing process is basically the same, so the master who fires the glass has already started working. Qin Wan thought that there should be many finished products in the next few days.
But when Qin Wan arrived at the place, she found out that although there is only one letter difference between colored glaze and glass, it is no less difficult to fire than colored glaze.
What's more, the formula Qin Wan gave was not complete, and the masters had to make several adjustments before they were able to produce a batch of glass.
It's just not that clear, it has many pores, it's not translucent, it's even white, but the light transmittance is very good.
Another problem is that the flatness is not enough, and it is impossible to make a truly flat large piece of glass. The largest one is only three feet square, and it is not regular, and looks a bit crooked from the side.
Qin Wan was a little disappointed: "I heard that good glass should be as clear as water, invisible when immersed in water."
The master handed over a piece of glass and said, "It can be made, but the proportions are still difficult to grasp."
This piece of glass is not even as big as a palm, but it is truly crystal clear. It takes hundreds of pieces of glass to make this small piece.
Qin Wan left this piece to the master: "That's it. Study how to make it carefully. If you succeed, there will be a big reward."
Qin Wan stayed in the glass workshop for only two days before returning to the capital with two carts of defective glass.
Tao Yao really liked these colored glasses: "Miss, these colored glasses should be different from the ones we use every day, right? Why don't you change the name?"
