Marin wanted to take out the honeycomb coal a long time ago, but considering the reaction of the allies Lamarck, Marin postponed taking it out. After all, he had exchanged a large area of land in the Ruhr region with coal mines from the Lamarck family. If he just took out the honeycomb coal technology as soon as he changed the territory, he would be able to see that he was pitting his teammates.

And Germany is a treacherous region that is accustomed to group groups of Europe, and if someone finds out that they are pitting their teammates and fighting in the future, Marin will be isolated. Therefore, Marin endured it for many years.

Originally, Marin had planned to take out honeycomb coal a few months ago. But as it happened, the old Hoffmans wanted Simon to marry Princess Anna of the Lamarck family. Then, Marin had to postpone the plan again. It wasn't until Simon got married on November 11 last year that Marin felt the time was ripe......

Of course, it is not taken out immediately, it needs to be foreshadowed. For example, a few days ago, two merchant ships returned from Panama, loaded with various goods purchased from the Ming Dynasty. Along with those goods, in addition to several Evenki falconers and Haidongqing eagles, there was also a letter sent back by Kongtai......

Of course, the letter was written in Chinese characters, and no one else could read it. Then, after reading the letter in a pretended manner, Marin happily announced aloud that Kong Tai had learned an amazing technique from the Ming Empire!

What kind of technology? Naturally, it's honeycomb coal!

Marin then hired potters, carpenters, and blacksmiths to "develop" the honeycomb coal stove and the handmade honeycomb coal press. said that it was research and development, but in fact, it was just Marin directing the craftsmen to restore his memory.

The honeycomb coal stove is very easy to make, let the potter pinch out the shape, throw it in the furnace to fire, and make a ceramic honeycomb coal stove, which is very simple.

The handmade honeycomb coal press was a bit more troublesome, and Marlin specially asked the carpenter to make a sample first, and then split it, and let the casting blacksmith cast the parts in a sand box casting method. The reason why sand box casting was chosen is for standardization. As long as the mold remains the same, the size of the parts of the manual honeycomb coal press cast in the sand box is about the same.

Marin tried it, and this handmade honeycomb coal press was similar to the one he used in later generations. In their previous life, their family lived not far from the Grand Canal and could easily buy coal from Xuzhou. In order to save money, many families went to buy a handmade honeycomb coal press, foot-pedal. The principle is very simple, that is, first use yellow mud and water to stir the anthracite powder into a dough form. Then, the handmade honeycomb coal press with the opening at the lower end is pressed down, compacted, and pressed with a few pedals.

At this time, in the manual honeycomb coal press with the opening at the lower end, there is a complete piece of honeycomb coal. Then, people will step on a pedal plate at the upper end of the honeycomb coal container, which is connected to a round plate at the upper end of the press, and the round plate has 12 holes on it, which are set on 12 fixed iron rods that are drilled. However, the round plate can move up and down, and when a person steps down from the top of the plate, the round plate inside the top of the press will press out the honeycomb coal that was originally pressed into the inside of the press. The damp honeycomb coal is then taken to dry before being transported and used.

Of course, Marlin was in a hurry, so he didn't go to dry or blow, and directly dried the honeycomb coal in the oven. And the way he lit the fire was also rude - throwing it directly into the pile of charcoal on the red-hot blacksmith's stove, and in a moment the outside of the honeycomb coal burned red......

Then there is the specific use, it should be pointed out that the 12 holes of the upper and lower three pieces of honeycomb coal must be aligned. Otherwise, the honeycomb coal on the top is not easy to ignite, and the honeycomb coal ignited below is also easy to extinguish or burn poorly.

But it is impossible to put the first red-hot honeycomb coal into the bottom of the furnace, or to add the next two honeycomb coals and align the 12 holes. In particular, the first red-hot honeycomb coal. So, at this time, Marin needed another "artifact" - fire tongs......

The tongs are shaped like scissors, but instead of a pair of blades, the front part is a pair of slender iron bars. Because there is no cutting edge, the two iron bars at the front end of the tongs can easily poke into two of the 12 holes of the honeycomb coal, and with a little force, the honeycomb coal can be clamped, lifted and put into the furnace, or the burned honeycomb coal can be clamped and replaced.

Moreover, because the iron bar can penetrate the hole of the honeycomb coal, when adding the above two pieces of honeycomb coal, people can also see whether the hole is right without eyes, as long as the front end of the tongs is stretched out and the aligned hole is found, the alignment of the hole can be completed.

Therefore, to play honeycomb coal, it must be equipped with a "magic weapon" such as tongs, otherwise it will be more troublesome. For example, when honeycomb coal is used in the Ming Dynasty now, there is no tongs, and you can only use an iron rod to poke down several times to complete the alignment of the honeycomb coal, which is very inconvenient.

After completing the ignition of the honeycomb coal at the bottom and the addition of the top two pieces of honeycomb coal (you can also add only one piece), the next step is to put an iron pot or kettle on the top of the stove.

To be honest, the honeycomb coal stove seems to be a little less powerful when cooking vegetables, especially when stir-frying. So, instead of thinking about using the honeycomb coal stove to cook rice, Marin put a large 5-liter tin pot on it and began to boil water......

In the early stage, because only the honeycomb coal at the bottom was ignited, the firepower was a bit insufficient. Therefore, it is necessary to fan the air with a fan at the air inlet at the bottom to speed up the combustion of honeycomb coal.

Then, Marin discovered a strange situation - there were no fans in Europe......

……

Don't laugh, Marin didn't brag either, but there really are no fans in Europe in this era......

Historically, it was in the 16th century, after the Portuguese opened up the route of the Ming Dynasty, that they discovered that there was such a thing as a fan in the world (for details, you can search for "European fans" in the encyclopedia). Then, brought back to Europe. In England, fans are said to have only been introduced at the end of the 17th century. Moreover, this is because of the influence of the Portuguese princess Catherine marrying Charles II. Because, at that time, with Queen Catherine, it was not only fans that were introduced to England, but also tea that had influenced Britain for hundreds of years......

Of course, the fan doesn't matter, because Europe is not hot in the first place. Tea broke out directly in England and became a favorite thing of the people.

But in this time and space, the Portuguese had not yet established trade relations with the Ming Dynasty, and only Marin had trade relations with the Ming Dynasty. Therefore, at this time in Europe, there are no fans anywhere else.

And in Ma Lin's hands, there is no banana fan used by later generations of Chinese people to fan the honeycomb coal in the early days. In desperation, he had no choice but to take out a beautifully made folding fan and fan the air inlet under the honeycomb coal stove for his subordinates.

Looking at the arrogant appearance of his guards, Marin said distressedly:

"Be careful, that's a precious fan!"

Can it not be precious? There is an inscription of Li Dongyang on the folding fan. Although Ma Lin got a few folding fans with inscriptions from Li Dongyang's hands, this is also a treasure. The folding fan of the first inscription of the Ming Empire is not expensive? If it weren't for the fact that Marin didn't have a fan in his hand now, he wouldn't have made this decision......

"Well, it looks like we have to introduce Daming's banana fan. It seems that it was the palmetto that made the banana fan, and it seems that Conté had to be notified to introduce a batch of cattogram seeds and plant them in Savannah in southeastern North America......"

In fact, Marlin can also make paper fans. However, the cost of paper fans is too high for ordinary people to afford. The banana fan is low-cost, lightweight, and windy, which is a good tool for fan ignition.

And in the absence of banana fans, Marin thought about it and decided to let the carpenters make a few thinner square planks. Holding this thin wooden plank fan, it is also windy, but it is not as light and windy as the banana fan, but it can barely be used......

Under Marin's extremely worried and painful eyes, Marin's guards fanned the wind hard, and finally boiled the first pot of hot water in Europe with honeycomb coal stoves......
