Abandoned woman from a poor family, she is addicted to wealth

Chapter 407 Colored Glass
That's right, Lu Jiu really wanted to promote Tian Li.

Tian Ren is also good, but Tian Ren has devoted all his energy to making pottery and is getting older, but Tian Li is different, he is still young, he is only in his early twenties this year, he has also studied, and after some experience, he can be promoted.

Lu Jiu looked at Ah Zhong Ah Yi who was a little nervous, and said slowly: "I can let go of the past, because there is really no work in the factory, but from today onwards, our work will come, as long as you give me a good job." Do it, everything."

Ah Zhong and Ah Yi breathed a sigh of relief, and quickly said: "Thank you for your generosity, Master, I will definitely do a good job in the future."

Lu Jiu sat down slowly, and said to everyone: "Everyone sit down, don't be so restrained, there will be more and more jobs in the factory in the future."

When everyone heard this, their faces were full of joy, especially the father and son of the Tian family, who were the happiest.

Ah Zhong and Ah Yi are not free. Although they are happy, they are not as happy as Tian's father and son.

Of course, their wages are not as high as the Tian family's father and son.

Tian's father and son are honest and responsible, but they have no work with Lu Jiu's high salary.

"So far, we have ten orders, but this order is not in a hurry because it will be completed soon. Our priority now is to make colored glass."

"Colored glass?" Ah Zhong was a little puzzled: "Don't we sell colorless glass?"

If the glass has a color, can it still be sold?

"Glass has many uses, not only for windows and display cabinets, but also for accessories, but white is too monotonous, so we want to add some changes to it."

Ah Zhong nodded: "So that's the case."

"The most important thing now is to make the colored glass first." Lu Jiu thought for a while, and then said: "We need to order some more molds, because the glass we need is very small, like glass beads the size of broad beans. There is still smaller glass, so some new molds need to be ordered, and this matter is left to Mr. Tian.”

"My boss, don't worry, I will definitely do a good job."

"I believe you."

Lu Jiu handed over the drawing to Tian Ren, and asked him to build it according to the mold on the drawing.

In fact, the production method of colored glass is very simple. When melting glass, a small amount of glass colorant is added to produce various colored glasses.

Copper oxide or chromium oxide produces green; cobalt oxide produces blue; manganese dioxide produces purple; tin dioxide or calcium fluoride produces milky white; uranium compounds produce yellow-green fluorescence; colloidal selenium produces carnelian; colloidal gold produces red , reddish purple or blue; cuprous oxide produces red, green or blue; ferrous compounds produce green and black in large quantities; iron compounds produce yellow.

What's more, when making glass, because the raw materials contain ferrous impurities, the glass is often greenish, and a small amount of manganese dioxide or selenium can be added to make it a colorless glass.

Now if you want green glass, you can leave it as is without adding manganese dioxide or selenium.

Lu Jiu gave Tian Ren several common glass colorants that he made, and asked him to add them when making them.

After explaining everything, Lu Jiu kept Tian Li and told him how to record attendance, and then left him 100 taels of silver for daily expenses, but every account must be clearly remembered , can not have a confused account.
