Chapter 153 The sycophant exploded

Ah Homi has a lot of fair skin, she is wearing a big Song Dynasty lady's shirt, her hairstyle is also like a big Song woman, and she has a step made into a small lychee decoration, if it weren't for the flying sword eyebrows, a short dagger at the waist, and the excessive steps under her feet, that appearance can really attract many prodigal sons.

Su You smiled: "Where did this lady come from?" My gift is exotic, and it doesn't match my sister's body. ”

After saying that, he took out a string of bracelets from his pocket, and Ah Homi's eyes immediately lit up: "Mine mine!" ”

As soon as he snatched the bead string into his hand, the resentment of the sky dissipated.

Fourteen beads, red, orange, yellow, green, blue, indigo, two, two, four lotus silver beads in the middle are separated, as beautiful as a rainbow in the sky.

The texture is clear, the color is gorgeous, Su You has promised others a long time ago, this is not about to go, this baby Leng didn't think about it.

Glass beads.

Take the bead string, open the gold buckle, and wrap it around Ah Mi's wrist to buckle it again.

Ah Homi stretched out his hand and watched the transmitted sunlight draw the rainbow on his wrist against the sunlight, his face full of fascination.

In fact, Chinese glass has been available for a long time, and glass and material vessels are actually branches of glass, and the materials used are too expensive, resulting in a lot of value.

Lead barium glass has appeared during the Warring States period, and emulsified glass jade clothes imitating jade have also appeared in the tombs of the Han Dynasty, and their verisimilimide has deceived the archaeologists who first saw it.

After the development of the Sui and Tang dynasties, many crafts were lost because of the war.

Su You doesn't understand lead barium glass, but soda-lime glass can't help him.

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

Su You knows the formula of ordinary glass, or because of the most abundant mineral deposits found in Meishan later generations - miscanthus salt.

In the glass industry, this is a very important clarifier to reduce air bubbles in the glass and increase the transparency of the glass.

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

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

Silica is quartz sand, calcium oxide is quicklime, sodium oxide is not, 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 performance of glass, in later generations, potassium-calcium glass is called hard glass, soda-lime glass is called ordinary glass, the price is two different things. Su You can't wait to turn all the sodium carbonate into potassium carbonate.

However, this is not possible at this stage, nor is it necessary.

The test kiln in Kelongli can reach a high enough temperature, in fact, the glass can be made long after the asbestos insulation layer inside the kiln is laid, but he is not very concerned about it.

One of the most important processes in glass making is pickling with rotten water.

Laboratory-grade sulfuric acid and hydrochloric acid can be prepared to remove ferrous compounds encapsulated in quartz sand.

This method can reduce the green color in the firing of the glass.

Of course, this is not enough, it also needs to be adjusted with a colorant.

After the ratio of green and yellow, it is possible to obtain a visual colorless glass.

The colorant does not have to worry about Su oil, and now the production technology of Da Song glass lamp is very mature. "Wuling Old Things" recorded: "There are a lot of lamp products, each with 'Su lamp' as the most, the big circle is three or four feet, all of them are made of five-color colored glass, landscape figures, flowers, bamboos and feathers, all kinds of wonderful, as if the color is also ......."

“…… In recent years, Xin'an has entered Yiqi, although the circle bones are all made of glass, and the number is 'boneless lamp'. ”

“…… It is forbidden to taste the glass lamp mountain, which is five zhang high,...... The hall is covered with a five-color glazed pavilion...... A small crystal curtain hangs between the small windows, and the tassel treasure belt is shining. The throne is set up, and it is suddenly like being in the Guanghan Qingxu Mansion. ”

The porcelain enamel formula of the Shijia porcelain workshop, coupled with the glaze coloring formula obtained from Bianjing by the Shi family using the relationship, is enough for Su You to make all kinds of glass.

He is a little stronger than the Great Song people, in fact, the increase of furnace temperature, the clarification of the formula of glass materials, the use of miscanthus clarifier, and the later heat treatment process.

Therefore, in the few days of waiting for Ah Homi's arrival, Su You tinkered with this in Kelong.

However, the main purpose of his glass is scientific research, using yellow colorants, mainly manganese compounds to adjust, and then blowing in the mold with an iron pipe, and then cutting with an iron sheet dipped in water, and burning the incision smoothly with an alcohol blowtorch, making a lot of glass test tubes, droppers, flasks, condenser tubes, measuring cups, concentration meters and other chemical laboratory equipment.

In order to make his roasted tea stand tall, he also pressed some three-piece gaiwan tea sets.

These things were made with the help of the pottery coal group, and as soon as the tea set came out, the little seventh brother was so excited that he almost urinated, and immediately used boiling water to make a cup for his omnipotent little master, wanting to slap the ass fiercely.

Then the sycophant blew up by itself, and a set of gaiwan tea sets were instantly scalded by boiling water.

Zhang Qi was so frightened that his soul flew away, and he fell to the ground with a plop.

This thing is not a bargain at first glance, if the iron-hearted master sues the government, the little seven children's shoes are exiled to Hainan Island, ah no, now it is called Tang'er, it is a seven-fold discount on the journey, because the Great Song Dynasty is really not far away.

Su You hurriedly helped Zhang Qi up and checked up and down: "Little Seventh Brother, are you hot?" Don't be nervous, this thing is broken and remelted again, and there is still a process missing, so it is easy to fry, so you should be careful in the future. ”

Zhang Qi's soul returned to his place at this time, and suddenly tears and snot spurted all over his face: "I'm scared of Xiao Qi, little master...... Woowoo...... I'm afraid I won't be able to lose even if I sell it......"

This baby only knew about crying at this time, and just now it was so scared that even the tear ducts were closed!

The process continues, in fact, glass anti-explosion also needs a heat treatment process, similar to iron treatment, after heating, put it into the holding furnace of asbestos stickers, slowly reduce the fire and temperature, so that it produces stress within a certain temperature range.

During the heat treatment period, Su You instructed the Tao Coal Group to make glass beads and test glass coloring.

This is simple and fun, after the glass melts, take the steel rod dipped out, roll it into beads on the hemispherical abrasive, cut off both sides with tweezers, fade the beads, put it on another hemispherical mold, spray the hole with a blowtorch, and use a thin conical steel rod to widen the bell mouth of the incoming line.

These are just the most basic techniques, and with the increase of molds in the future, Zhang Qi's skills and improvement of their techniques can also make a lot of glass products.

For example, crystal balls, glass bottles, cups, plates, bowls, glass mirrors......

These are the later words, that night Su You was in Fang Zhiwei to pick up Ah Homi and Mr. Fan and his party, waiting for the arrival of the big ship of the Second Forest Department.

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

The things of the second forest department are very popular, and in the trading hall on the first floor of the Zhuyuan Building, businessmen from all walks of life came to shake hands with Mr. Fan cordially.

The handshake was not seen by others, everyone touched their fingers in the sleeve cage with affection, and then looked at each other ambiguously and smiled, deal!

Su You originally came over to see the excitement, but when he saw a group of white-bearded old men with such hot eyes, he almost vomited on the spot. Turn around and leave, go to the Arctic Courtyard to send things to Little Heavenly Master and Wei'er!

Wei'er, this little girl, has been a little weird lately, and things have broken down quickly, but she hasn't sent them back, so she only asks Su You to send a new past.

And it seems that I like everything, porcelain, copperware, knives, music boxes, all kinds of food and play, it's just a little Pixiu who can't be fed.

However, these things are not worth a lot of money in Su You's eyes, as long as Wei'er likes it, she will give it, so it is a big pack every time.

Therefore, this time, in addition to various experimental equipment, there is another set of glass tea sets and a string of small glass beads.

This visit is very important, and it involves the Shijia's industrial transfer plan, so the benefits should be prepared.

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

But don't think about it, don't think about the latest lathe for processing iron workpieces, this lathe is mainly used for processing wood in the second forest.

According to Ah Homi, the surrounding Tibetan people and Qiang people are very fond of using wooden bowls to exchange wooden bowls for their cattle and horses, and there is no more cost-effective business than this.
