Convincing the old lady is the most important step, if you don't sweep the house, how can you settle the world.

Since it has been decided, we must go all out, the time is still early, things have to come step by step, Yang Wenli plans to fire the bone china successfully first.

What he said to the old lady just now that the bone china is about to be fired successfully is not a joke, but a real thing. The recently fired bone china has basically met his requirements, but he still wants to do better, so he has not yet declared it successful.

He looks stupid to make trouble for himself, but in fact, isn't it creating difficulties for those who come after him? Even he, the original author, is difficult and tortuous, and the difficulty of later imitators to achieve the same quality of bone china can be imagined.

That is to say, for a long time, he has been an exclusive monopoly on products, and windfall profits are a matter of course.

So there are two sides to everything, if he is not demanding, then as early as half a year ago he can be fired in large quantities for sale, but others are also easy to imitate, and the price is naturally not high.

……

Yang Wenli's latest formula is 50% calcium oxide, 23% alumina and silicon oxide, and 27% clay, and the best formula in later generations is almost the same.

Yang Wenli chiseled the sealing mud with an iron chisel, and then flashed to the side, and the residual heat needed to be drained before the lid of the reverberatory furnace could be removed, otherwise it would be easy to burn people.

After about ten minutes, Yang Wenli shouted at Yang Rentian and Yang Rendi, who were waiting on the side: "Lift the cover"

This lid is not light, it is made of half-foot-thick clay, weighing about 300 catties, and only these young people have the strength to lift it open.

When the lid was removed, a bone china prototype on a clay platform in the furnace was revealed.

"Alas" ...... "噫...... Yang Wenli sighed first, and then was pleasantly surprised.

It turned out that he began to see a pile of broken bone china, and thought it had failed again, but then he saw a small wine cup in the middle of the fragments, which was actually intact.

He didn't care that the wine cup was still hot, and took a pack of it to his eyes with his cuffs and looked at it carefully. It's beautiful! The crystal clear white, glowing with a jewel-like charming luster, it can not find a trace of flaws in the upper and lower parts of the body, the shape of the instrument is upright, the imitation is made of a whole gemstone natural casting, it is really a rare treasure in the world!

"Young master, this wine cup is so beautiful." Yang Rentian and Yang Rendi also came over to inspect, and Yang Rentian couldn't help but admire.

"Huh! Is it? It was indeed beautiful, so it was precious, and this one was not much worse than silver of the same size. Yang Wenli couldn't help but be complacent.

"Young Master, is this considered a success?" Yang Rendi couldn't help but interject and asked.

"It's a success, it's not a success. This cup was a success, but several other prototypes failed.

Let's go first! I'm going to have to look for the reason. After Yang Wenli finished answering, he gave the order to evict the guest, he needed to think in a quiet environment, and the presence of outsiders would affect his thinking.

"Whoa! Then we'll quit first. Yang Rentian said on behalf of the two. Then they turned and retired, knowing that the young master, who was already in thought, might not have heard them speak at all.

As before, the same batch of trial products included cups, bowls, basins, plates, pots, cups and other commonly used porcelain in the family, and the others were broken, but the cup was intact, which was a huge progress.

"The cup is small in size, so it is not broken, so can it be concluded that the cooling time is not well mastered?" Yang Wenli muttered to himself like a demon.

With this little cup, the next experiment is much easier, don't change the recipe, don't change the furnace temperature, maybe don't change the firing time, the only thing that needs to be changed is the cooling time.

But the time is indispensable, and after another ten days, it was fired in the furnace again, first the tire burned, and three days later the glaze burned.

This time the surprise is even greater, only the pot and basin are broken, this time you can definitely find the reason, as long as you make a slight adjustment, it is enough, but it may also be necessary to fire separately in the shape of the divider, in short, it is getting closer and closer to success.

After another half a month, the third test firing out of the kiln, Yang Wenli specially invited the old lady to come, the joy to share with the family, this is the result of his efforts for more than a year, he wants to witness with his mother.

Yang Wenli personally waved the iron drill to chisel off the soil of the observation hole, and after waiting anxiously for more than ten minutes, he shouted loudly: "Remove the cover."

This time, it was Yang Renri and Yang Renyue, the two youngest teenagers, who were porters, after the two of them lifted the lid of the furnace.

"Wow!" Several people present, including Yang Wenli himself, couldn't help but exclaim. After removing the lid, I saw that several pieces of porcelain of different sizes on the clay platform were all intact, emitting a charming white light, which was so white and pure, more crystal clear than the top Hetian white jade material, comparable to treasures.

"My son, you have finally succeeded, it's hard for you, I don't know how many hardships you have gone through, and today you have achieved a positive result." The old lady praised her son very rarely, mainly because these bone china were so beautiful that even she had no doubt that they would sell for a sky-high price.

"Young Master, congratulations on your success!" Xiaohong Xiaolu and the two young family members also sent their blessings.

"Hahahaha! Rejoice and rejoice, our Yang family will add a money-making weapon from today, and the Yang family will prosper from now on, just around the corner, hahahaha! Yang Wenli laughed loudly, arrogant.

……

The bone china was successfully fired, but it would not be fired in batches immediately, because Yang Wenli still had an important matter to do.

Forge knives, cast a batch of sabers for himself and ten young people. The iron material has long been available, and it is the batch of blades that Yang Rentian and they have captured.

Yang Wenli is not a blacksmith, so he does not know how to make knives. The knife was contraband, and it was impossible for him to ask a blacksmith to help make it, so he had to choose to cast it.

If there is no special process, the cast knife will definitely be cut and broken, because its tissue density is not enough, of course, it is not as good as the beaten knife.

This is a difficult problem, later generations have cold rolling and hot rolling, which can not be done in ancient times, he does not have those large equipment.

It seems to be a lot more difficult to engage in hot extrusion, but it is the only thing he can try, and other methods will not work.

The first problem in front of Yang Wenli was that he did not have so many iron to make large tools, and the limited conditions forced him to develop simple tools.

After a few days of contemplation, Yang Wenli thought of the manual mechanical rapeseed oil pressing equipment of later generations, which was super simple and only needed a screw......
