Placing the stone yellow grinding powder into it can greatly reduce the temperature requirement and obtain the molten glass.

Looking at the liquid that was emitting a bright red color, Lu Ming, who was guarding the side, couldn't help but be shocked: "Young master, this is the liquid glass you are talking about? It is as clear and bright as molten iron!"

Qin Feng personally went into battle, wearing thick gloves, took out the liquid glass from the cellar furnace, and yelled at Lu Ming: "Don't be stunned, hurry up and pour it into the sink!"

Only then did Lu Ming come back to his senses, and took out an urn of liquid glass from the cellar furnace and poured it into the tin tank along the funnel.

The tin bath has been pre-filled with water.

When the molten glass was poured into the tin tank, I heard a loud sound, and a lump of black things sank directly to the bottom of the water.

"it!"

Qin Feng looked at his painstaking masterpiece, and let out a miserable scream: "Nima! I've been busy all day, and the failures are too neat!

Qin Feng looked at the liquid glass that was instantly cooled by the water, patted his head, and secretly scolded himself for being confused: "Failure is success! The temperature of the water is too low and the density is not dense enough to allow the molten glass to be suspended above......"

But looking at the black thing, Qin Feng suddenly opened his mouth again, and slapped his thigh: "Lu Ming, you immediately order the workshop to start work with all its might, casting two iron boxes, and leaving an even gap space in the middle." ”

Qin Feng was about to bite someone a second ago, but this second he wagged his tail again.

Lu Ming was confused, but he still complied, went to the workshop, and ordered the blacksmith to fire on fire, because there were many ready-made iron plates, so it was not difficult to cast iron boxes, and soon Lu Ming sent the boxes to the glass room.

Qin Feng repeated his old trick, introduced all the remaining glass solution into the iron box, and used the gap in the iron box to forcibly form.

Over time, the molten glass gradually cools, eventually forming a crystal clear glass.

Qin Feng smashed the bottom of the glass along the gap inside the box, and then reversed the box and poured out the four pieces of molded glass.

Looking at the crystal clear glass pages, Lu Ming was stunned.

I don't know how long it took to come back to my senses, and I looked incredulous: "Shao...... Young master, I know the glass, but most of them are glass balls, or glassware, such a large sheet of thin glass, small unheard of. ”

Qin Feng's whole person was already slumped on the ground, panting for breath in a tired gulp.

But looking at the four thin glass pages, my heart is full of a sense of accomplishment.

After many twists and turns, this glass page has finally been refined!

Lu Ming squatted on the ground, because the glass page was too thin, Lu Ming didn't dare to touch it, so he looked down like this, his eyes were full of amazement, but then he was puzzled: "Young master, this glass sheet is good, but it's too fragile, what can you do?" It's better to directly build an iron ball mold and refine the glass ball." ”

Qin Feng rolled his eyes, and said angrily: "What do you know! Glass balls or glass vessels, it's not that I haven't seen them in the palace, this glass page is a good thing." ”

Since he decided to refine glass, Qin Feng was not for the Lord of Qiyang, but to "give gifts" to the saint.

After all, he had formed a bond with the Lin family before, and the ghost knew what kind of indiscriminate means the Lin family would use to retaliate against the Qin family.

Qin Feng is going to make this glass into a "glass window" and inlay it directly in the imperial study, so that the sage can see Qin Feng's masterpiece as soon as he looks up, and he will miss the Qin family's good ......

Qin Feng regained some strength, pointed to the glass, and said excitedly: "You take someone to polish this glass page into a boxy, and then order a carpenter to make it into a window, how big is it...... Afterwards, I asked Qin Xiaofu to send you the size of the window in the imperial study. ”

Lu Ming looked at Qin Feng blankly, these words were beyond his cognition.
