In the afternoon, in a corner of Guangling City, in a glass factory, the imperial concubine Yang Lihua was inspecting, and a group of female employees surrounded her. Although they had different identities, they were all dressed the same: wearing work clothes, bibs, sleeves, cloth shoes, and work hats.

There is a safety production system in the factory, and no matter who is it, it must be followed. Because there are many rotating parts in the production equipment, it is easy to get involved in the hair, causing casualties. Therefore, both men and women have to pick up their hair before entering the factory and put it in the hat.

Even if Yang Lihua is a noble concubine, she is no exception. If she has an accident in the factory, no one can afford the consequences.

If there is any problem with the production process of the factory and Yang Lihua will be caught, the consequences will be serious: Yang Lihua does not visit as a guest, but as the highest manager, to check whether the production processes of the factory comply with the requirements of the rules and regulations.

She is in Chang'an on weekdays and understands the operation of Guangling Factory based on various reports. But now she has finally come back and naturally has to read it inside and out.

This glass factory was put into production seven years ago. At that time, the emperor was still in the Qiandi residence and served as the general manager of Yangzhou, so he rented the factory for the construction of the concubine of the female family of King Bin.

Now seven years have passed, the production scale of the factory has been expanding, and the production of various glass products including flat glass and glassware has been very considerable every year. It can be said to be a chicken laying golden eggs.

In addition to the glass workshop in Guangling, Yangzhou, the glass workshops in Xiyang, Huangzhou, Yecheng, Xiangzhou and other places are also chickens that lay golden eggs, and the person in charge of the "chicken coop" is the imperial concubine Yang Lihua.

The production and sales of glass products are important industries of the royal family. Since nearly twenty years ago, they have earned a lot of profits for the secret residence and the current ban. Yang Lihua has been in charge of this industry for nearly twenty years. All glass workshops of the royal family are under her strict management.

It is precisely because of this that Yang Lihua knows the glass making process very well and is very serious during on-site inspections. The technical backbone and managers in the workshop are all people she brought out.

Now everyone saw the imperial concubine staring at the glass kiln intently, looking like she was preparing to pick bones in the eggs, and they were so nervous that their palms were sweating.

The furnace in front of me is already at the time when the glass comes out of the kiln. Bright molten glass liquid flows out from the kiln and then flows into a semicircular container with round holes at the bottom.

The temperature of the glass liquid flowing through the round holes drops slightly, becoming more viscous, the color turns bright red, and continues to fall in a cylinder shape.

A cross steel knife driven by water continuously rotates, slashing at the sticky glass liquid, slashing it into short cylindrical glass blocks.

The glass block falls into the guide groove at the lower end, and then rolls down into a pair of screws placed horizontally, and gets stuck in the gap between the screw threads.

The screw driven by hydraulic forces continuously rotates, driving the glass block forward and constantly rotates and rolls. The glass block is still soft at this time, so the shape gradually turns into a ball.

The length of the screw is two meters. At first, it was a bright red glass block. After the appearance gradually became a spherical shape, it gradually became darker. After the complete walk, the temperature dropped, and the round glass balls were also formed.

Yang Lihua used her glove-wearing right hand to pick up a slightly warm glass ball from the tray and looked carefully at the light.

The glasses in this kiln are all purple glass, so the glass balls that Yang Lihua held in her hand are purple. This glass ball is the size of a pigeon egg, crystal clear and free of impurities.

Yang Lihua looked carefully and found no flaws in the glass ball. Then she took the glass "colorization card" handed over by the escort and compared it carefully.

This glass color card is "purple" with different purple colors on it and then has a corresponding name, one of which is purple, called "Bone Spiral Purple".

Bone snail purple is the most noble purple in the western Roman and Persia. In recent years, various glass factories of the royal family have been trying to develop this purple formula to make glass products with Bone snail purple, which can be sold at a better price when exported.

After years of hard work, the technicians at Guangling Factory finally made a breakthrough. They developed a new formula, and the purple glass burned out looked very similar to the purple snail purple.

That was the end of spring this year. Now, Yang Lihua has verified this fact with her own eyes. She put the glass beads back on the tray and nodded with satisfaction: "No, not bad."

The Guifei, who had always been strict, was sure that the technicians breathed a sigh of relief. Seeing that the factory was very hot, everyone quickly asked the Guifei to go outside to speak.

It is late summer now, and the weather is humid and hot, so everyone is afraid that the imperial concubine who is in a high-temperature factory will be heatstroke. If this is the case, it would be a bad thing.

Before leaving the factory, Yang Lihua poured a cup of salt and boiled water from the water tank and took a few sips to confirm whether the workers' "high temperature benefits" were implemented and whether salt was added to the water.

When she moved to the "office", the maid fanned the concubine with a round fan. Yang Lihua didn't care about drinking the ice drink she sent, and continued to urge relevant personnel to pay attention to various precautions and asked everyone to work overtime to produce large quantities of purple (bone snail purple) glass products. Of course, you should pay attention to safety production.

"Nanyang Trading Company has been selling stained glass products to Western countries in recent years. In the future, the proportion of purple glass products will increase significantly. By the end of this year, fleets will go to the extreme west. They will bring a large amount of purple glass products, so you must be prepared now."

"There are many factories that can make purple glass. No matter what other companies don't care about it, the purple glass of Guangling Factory must be similar to the purple of bone snail..."

"You should report the rewards from relevant personnel as soon as possible. Also, the formula must be kept strictly confidential and don't leak it."

Yang Lihua said a lot in one breath, and finally explained what she should have done. She took a few sips of ice drinks and added: "The formula is kept confidential for two years, and it will be transferred for a fee as usual. How to do it according to the rules."

"Also, the glass beads as big as pigeon eggs are too single, what about bigger ones? What about the new product you mentioned a few days ago?"

The imperial concubine asked, and those who were prepared quickly brought up the "new product". It was a square wooden box, the size of a wine jar. From this, it can be seen that the items contained inside are quite small.

The maid opened the wooden box, took out the item, and then held it in front of Yang Lihua. Yang Lihua looked closely and saw that it was a huge glass ball placed on the sandalwood base.

Purple glass ball.

This glass ball is the size of a coconut, round all over, with a purple color similar to the snail purple, but the ball is not clear purple, and there is a gorgeous purple color at the center of the ball, as if it is a mixture of purple colors of different shades.

This ball of purple is like smoke and mist, the size of a fist. It looks like a touch of fairy energy in the nine heavens inadvertently "frozen" the purple glass, as if it contains mysterious power. As long as the glass ball is broken, the ball of purple air will gush out.

Yang Lihua looked at the purple glass ball with her eyes fixed on her eyes, as if her mind was being taken by it. After a long time, she came back to her senses and asked with a little love: "So beautiful! What is the name of this thing?"
