The power of the state was unimaginable, and in just over a month, the first batch of ten cars, a total of more than 200 barrels, weighing more than 1,000 stones, was sent to the Tokai-gun shipyard.

This is the result of not using the train, but taking the water route directly from the north of the town, and then switching to the land route.

And Wang Li also didn't expect that it only took so much time for his music to be handed over, and the court found a solution, and also sent the physical object over.

It's not much, but it's enough for experiments.

Raw lacquer, milky white, after opening the barrel, there was a faint sour smell, Wang Li directly tried it with his hands, and immediately wiped it off, but found that his hands were still stained with some slight white.

In fact, not only Wang Li felt a little surprised, but because of this incident, there was still a joke in the court.

Li Yuanji hadn't thought about this matter before, and those ministers who lived in the temple naturally didn't care about these little things.

Even Sun Simiao also discovered that dry paint can be used in medicine This thing was not the first to be discovered by himself, this thing is actually recorded, and it first appeared in "Shangshu. Yu Gong", but because these books are not medical books, and there is a secretary and supervisor, although Sun Simiao can consult them, he rarely consults other books except medical books.

After discovering that there was no record in the medical book, Sun Simiao recorded it in the medical book he wrote and explained it in detail.

However, for the name he gave himself, it was changed, and it was replaced by the name in the book.

Of course, Sun Simiao's oolong can only be one of a series of oolong incidents, an insignificant one.

Although lacquer and lacquer have long been recorded, there is almost no record of its medicinal effects, only that it has an insect repellent effect, so Sun Simiao's discovery is not without effect.

And what embarrassed Li Yuanji the most was that after the order was passed out, the supervisor was notified separately at the same time, which required the supervisors to pay more attention to this kind of lacquer tree when they visited, to see where there was a group of growth, one is statistics, and the other is to facilitate future collection.

It's not a big deal, so there's nothing to hide.

However, as a result, the Ministry of Industry came to the door.

And then the result was that the Ministry of Industry said a fact that made Li Yuanji feel very MMP.

Basically, there is no need to investigate, for the lacquer tree, there is a record on the part of the Ministry of Industry, and there are also records of use, but no one cares, and no one thinks about asking the Ministry of Industry, so it takes a lot of time to go around, and the final problem is back to the Ministry of Industry.

And even now, there is a large amount of lacquer stored in the warehouse of the Ministry of Industry.

How to say, the pillars, doors and windows of the palace, all the desks and chairs in the palace, the bookshelf decorations, everything you can see that is not the essential color of the object, all of them are made of lacquer.

The reason why the colors are different is because when the Ministry of Industry uses them, some other natural pigments are added to it, so the colors are different.

The scope of the use of raw lacquer is too wide, and the court uses the best quality wood lacquer.

It is characterized by the fact that most of them are wild, the trunk is relatively thick, the paint produced is relatively thick, the dryness is good, the blackness is large, the adhesion is strong, the strength is high, and the durability is strong.

The folk use is mostly small wood paint, most of which are artificially planted, and the paint produced is light in color, good in transparency, good in luster, slightly worse in dryness, and not as good as in large wood paint.

Because this kind of lacquer tree is abundant and versatile, the price is cheaper.

Of course, there are not many ordinary people's homes, and many people build their homes basically once in a lifetime, and they will tinker with it in the future.

And the most used is the coffin, each coffin must use raw lacquer, no matter how much the people saved, they will not save in this regard.

Of course, in addition to this purpose, all shops are also decorated with lacquer.

Therefore, the Ministry of Industry directly told Li Yuanji the origin of the lacquer they knew, the nearest of which was Ankang County, and the lacquer stored in the palace was mostly produced in Ankang.

In order to make a brighter color, the craftsmen have a small team of more than ten people all year round to study the lacquer, and constantly experiment, it is no exaggeration to say that the craftsmen in the Ministry of Industry, you tell him what color you want, and within a long time, they can make the corresponding color of the lacquer.

The craftsmen are very cautious about the study of this aspect, because it is a palace article, and those raw materials that are considered irritating by traditional Chinese medicine are not allowed to be used, so the raw materials for color matching are mostly pollen of various colors.

At the same time, because the flowers are directly glued into water, the lacquer will be diluted, and the color change is not large.

Therefore, the craftsmen are trying to dry the water pressed out, leaving only some powder, adding powder directly and stirring when mixing, and if necessary, mixing some flower water.

Of course, many people don't know these things, including Li Yuanji, who doesn't know that the production process of these things used in the palace will be so complicated.

This also made Li Yuanji decide, when there is something in the future, it is best to ask the people around him first, so as not to be like this time, busy with a lot of work, and the result is not a lot of effort.

It can not be said that it is a busy work, the origin of different lacquer, in the use of the effect will naturally be a little different, although the same lacquer, the effect in some places is good, then naturally the effect in some places will be poor, so looking for lacquer, one by one, it is still very necessary.

"Wang Gong, this raw paint must be used within an hour after the barrel is opened, otherwise the paint surface will dry up and harden, although what is wasted is only this layer on the surface." The official who came to deliver the paint reminded.

"Lacquer?" Wang Li frowned, and looked at the milky white liquid in the bucket again, slimy, he knew this thing.

"Yes, it is lacquer, it is very widely used, up to the court, down to the funeral, all of them are lacquered, the difference is the variety and quality of lacquer, these are just raw lacquer transported from the north of the town, other places are also looking for, and the later stage will gradually be sent over for testing, to see where the lacquer effect is better. Of course, His Majesty also ordered the Ministry of Industry to send a team of graduate lacquer students, and they would study the lacquer here to make it more suitable for warships. ”

"Are you sure there's nothing wrong with this thing soaking in water all year round?" Wang Li couldn't believe it, because this situation had happened here more than once.

For example, even if a good artillery used on land is moved to the ship, the corrosion resistance is reduced, but after it is thrown into the sea, the rate of corrosion is still not acceptable.

The steam engine, which has no problem on land, has never been able to solve the problem of water leakage when it reaches the sea, and the scientists of the steam engine team of his academy are still having a headache with this problem until now.

Therefore, Wang Li is not unwilling to believe it, but various previous cases tell him that this matter is not so simple.

"There must be a problem, but it shouldn't be big, Wang Gong, please move!" The official smiled slightly and led Wang Li to a car behind.

There was a big bucket in the car, which was filled with clean water, no, the water was a little muddy.

Then next to the vat took a few pieces of palm-wide, about the length of a small arm's rectangular steel plate, the color of the steel plate is no longer the original color, but changed to brown, the whole surface is smooth and flat, although not very beautiful, but it is also undeniable the role of lacquer.

"When I set out from the north of the town, I asked people to do it, which was to put the iron plate in the lacquer, and then take it out to dry, and I brought it all the way." The official continued to point to the big bucket on the car, and the soldier next to the car jumped up directly, reached out and fished out a few iron plates in the bucket and handed them down.

"These are all made in the same batch, these are the ones in Wang Gong's hand are as for the outside, there is no water, and these are put into the bucket after they are completely dried, in order to simulate the seawater, even put a lot of sea salt in it, as of today, these iron plates have been soaked in this bucket of water for a month and five days."

Wang Li not only had one in one hand, but also put them together to explore.

The color of the steel plate soaked in simulated seawater is obviously a little dull, although the other luster is not bad, but there is still a clear difference between the two.

couldn't even wait for someone to get a dry cloth, Wang Li directly used his sleeve to dry the iron plate that had just been taken out of the water, and then carefully felt that it was a little damp, but it was not as wet as he imagined.

Although Wang Li is an expert in steel, he has been here for a few months, chatting a lot with the engineers of the shipyards, and he also knows a little about shipbuilding.

If you just look at the results, the effect of lacquer is good.

But Wang Li still saw the problem at a glance, although it was soaked in water, and the whole was moving, but the steel plate and the barrel were moving at the same time, that is, the friction between the water and the steel plate was almost negligible.

Thinking of this, Wang Li directly picked up a stone on the ground, and slid it down on the iron plate with force, and an obvious trace appeared instantly, revealing the original color of the steel plate.

Seeing this, Wang Li was not only slightly shocked.

Scratching the paint surface, the color of the exposed steel plate is a little rusty, but as an expert just now, how could he be confused by these illusions?

How could it not rust just now? Even if it is left in a dry place, it will rust over time, unless it is constantly baked in a fire.

And the rust exposed by this steel plate is completely acceptable, or rather, this is the problem of the steel itself, to solve this problem, unless it is to study a steel that does not rust at all, but it is very difficult.

But in any case, the effect of this steel plate is the best I have seen so far, even if there may be various problems, but as long as the effect is better than the current one, it is enough, at least it is a kind of progress, at least it is a new idea.
