Chapter 153: Flattery explodes

Atunmi's skin is much fairer. She is wearing the Luo shirt of a lady from the Song Dynasty. Her hairstyle is also like that of a lady from the Song Dynasty. She wears a walking stick decorated with small lychees. If it weren't for the flying sword eyebrows, she would have a short dagger at her waist.

, and the overly large strides underfoot, that look can really attract a lot of prodigals.

Su You smiled and said: "Where does this ladylike lady come from? My gift is full of exotic style, and it doesn't match my sister's outfit."

After saying this, he took out a bunch of bracelets from his pocket, and Atunmi's eyes immediately lit up: "My, my!"

Grabbing the string of beads into his hand, all the resentment in the sky disappeared.

Fourteen beads, red, orange, yellow, green, blue, indigo and purple, arranged in pairs, separated by four silver beads with a lotus pattern in the middle, are as beautiful as a rainbow in the sky.

The texture is clear and the color is bright. Su You has promised to others a long time ago. It's time to set off, but the boy didn't think of it.

glass bead.

Take the bead string, open the gold buckle, wrap it around Atunmi's wrist and fasten it again.

Atunmi stretched out his hand and looked at the sunlight to see the rainbow painted on his wrist by the transmitted sunlight, with a look of intoxication on his face.

Chinese glass has actually been around for a long time. Glaze and glassware are actually branches of glass. The materials used are too expensive, resulting in high value.

Lead-barium glass had already appeared during the Warring States Period, and jade-like emulsified glass pieces of jade clothing had also appeared in tombs of the Han Dynasty. Their realism once deceived the archaeological experts who first saw them.

After the development of the Sui and Tang Dynasties, many crafts were lost due to wars.

Su You didn't understand lead-barium glass, but soda-lime glass didn't bother him.

Because the glaze of porcelain is actually a kind of emulsified glass in a broad sense.

Su You knew the formula for ordinary glass because of the richest mineral deposits of Glauber's Salt discovered in later generations in Meishan.

In the glass industry, this agent is a very important clarifier, which can reduce bubbles in the glass and increase the transparency of the glass.

As a place of production, these industries in Meishan are naturally quite developed.

Soda-lime glass is composed of silica, calcium oxide and sodium oxide.

Silica is quartz sand, calcium oxide is quicklime, and there is no sodium oxide, but a mixture of sodium carbonate and potassium carbonate can be extracted from plant ash water.

Potassium carbonate is not an impurity. On the contrary, it can also improve the properties of glass. In later generations, potassium-lime glass is called hard glass, and soda-lime glass is called ordinary glass. The prices are two different things. Su You can't wait to turn sodium carbonate into

It's better to turn it into potassium carbonate.

However, this is impossible and unnecessary at this stage.

Ke Longli's test kiln can reach a high enough temperature. In fact, glass can be made after the asbestos insulation layer is laid inside the kiln, but he is not too concerned about it.

There is an important process in glass making, which is pickling that has been worn out.

Laboratory-grade sulfuric acid and hydrochloric acid can be prepared, through which ferrous compounds coated on quartz sand can be removed.

This method can reduce the green color in glass firing.

Of course, this alone is not enough, you also need to use colorants to adjust.

After mixing green and yellow, visually colorless glass can be obtained.

There is no need to worry about the colorant of Su oil. Nowadays, the production technology of glass lamps in the Song Dynasty is very mature. "Old Stories of Wuling" records: "There are many types of lamps, with 'Su Deng' being the most popular. The large circle pieces are three or four feet long, and they are all five colors."

Made of colored glaze, there are landscapes, figures, flowers, bamboos and feathers, all kinds of wonderful things, just like colored instant noodles..."

"...In recent years, it has become more and more strange to enter Xin'an. Although the bones in the ring are all made of glass, it is called the 'Boneless Lamp'."

"...In the ban, a mountain of glazed lanterns was built, which is five feet high....The hall is paved with five-color glazed pavilions...There are small crystal curtains and tassel belts hanging between the small windows, creating a dazzling reflection. There is a throne in the middle, which makes you feel like you are there.

It is also in Guanghan Qingxu Mansion."

The porcelain glaze formula of Shijia Porcelain Factory, plus the glaze coloring formula obtained from Bianjing by the Shi family through their connections, were enough for Su You to produce various colors of glass.

What makes him better than the Song Dynasty people is actually the increase in furnace temperature, the clarification of the glass material formula, the use of Glauber's salt clarifier, and the later heat treatment process.

Therefore, Su You tinkered with this in Kelong during the few days he was waiting for Atunmi's arrival.

However, his main purpose for making glass is scientific research. He uses yellow colorant, mainly manganese compounds, to adjust it, then dips an iron pipe into the mold and blows it, then cuts it with an iron sheet dipped in water, and burns the cut smooth with an alcohol blowtorch.

, produced a lot of chemical laboratory equipment such as glass test tubes, droppers, flasks, condensers, measuring cups, concentration meters, etc.

In order to make his fried tea more elegant, he also bought some three-piece tea bowl sets.

These things were made with the help of the Tao Mei Group. As soon as the tea set came out, Xiao Qi Ge was so excited that he almost peed. He immediately made a cup of boiling water for his omnipotent young master and wanted to slap it hard.

A moment of flattery.

Then the flattery exploded on its own, and a set of tureen tea sets was instantly scalded to pieces by boiling water.

Zhang Qi was so frightened that he fell to the ground with a plop.

This thing is definitely not a bargain at first glance. If the owner is determined to sue the government, Xiaoqitongshoe will be exiled to Hainan Island. Oh no, now he is called Dan'er. It will be a 30% discount on the distance.

Discount, because there is really no place further than Song Dynasty.

Su You quickly helped Zhang Qi up and checked him up and down: "Brother Xiaoqi, are you scalded? Don't be nervous. This thing can be broken into pieces and remelted in the furnace. There is still one more step left, so it is easy to explode. Please be more careful when handling it in the future.

"

Only then did Zhang Qi's soul return to his original position, and tears and snot filled his face: "I scared Xiao Qi to death, young master... wu wu wu... I'm afraid I won't be able to pay for it if you sell it..."

Only then did the baby start to cry. Just now, he was so scared that his tear ducts closed!

The process continues. In fact, the anti-explosion process of glass requires a heat treatment process, which is similar to the treatment of iron. After heating, it is placed in a holding furnace with asbestos stickers, and the firepower and temperature are slowly reduced to produce stress within a certain temperature range.

During the heat treatment period, Su You instructed the ceramic coal team to make glass beads and test the coloring of the glass.

This is simple and fun. After the glass is melted, dip the steel rod in it and roll it into beads on a hemispherical grinding tool. Use tweezers to cut off both sides, take the beads out, place them on another hemispherical mold, and spray with a blowtorch.

To open the tunnel opening, use a thin conical steel rod to widen the bell mouth of the incoming line.

These are just the most basic techniques. In the future, with the increase of molds and the proficiency and improvement of Zhang Qi's techniques, they will be able to make many, many glass products.

Such as crystal balls, glass bottles, cups and dishes, glass mirrors...

These are things for later. That night, Su You met Atunmi and Mr. Fan in Fangzhiwei, waiting for the arrival of the Erlin Department's ship.

Early the next morning, the big ship arrived, and another cargo needed to be emptied.

Things from the Erlin Department were in great demand. In the trading hall on the first floor of the Huiyuan Building, businessmen from all walks of life came over to shake hands with Mr. Fan cordially.

The handshake is not allowed to be seen by others. Everyone touches their fingers affectionately inside the armholes, then looks at each other ambiguously and smiles, seal the deal!

Su You originally came along to watch the fun, but when he saw a group of old men with white beards being so mean-spirited, he almost vomited on the spot. He turned around and left, going to the Arctic Courtyard to send something to Little Celestial Master and Wei'er!

The little girl Wei'er has been a little weird lately. Things break quickly, but she didn't send them back. She only asked Su You to send new ones.

And he seems to like everything, including porcelain, copperware, knives, music boxes, and all kinds of food and playthings. He is simply a little Pixiu who can’t get enough to eat.

However, these things are not worth a lot of money in Su You's eyes. As long as Wei'er likes them, she can give them to her, so every time she has a big pack.

So this time, in addition to various experimental equipment, there was also a glass tea set and a string of small glass beads.

This visit is very important and involves the Shi family's industrial transfer plan, so the benefits must be sufficient.

In addition to Shijia's various tools, there are also new sawing machines, manual punching machines, foot-operated work platforms, and a huge lathe.

But don’t think too much about the latest lathe for processing iron workpieces. This lathe is mainly used by the Erlin Department to process wood.
