Yipin County Magistrate: Start with invincibility

Chapter 462 Refining Cinnabar with Glass Instruments
Of course, this is just a hot thought in Qin Feng's head. Even if it is really done, it is not done now.

Compared to this, the most urgent thing is to make what you need as soon as possible.

Thinking of this, Qin Feng couldn't help but move a little faster.

After one night's work, Qin Feng has crushed most of the cinnabar mine into pebbles.

Wei Quanyou also prepared the mold that Qin Feng wanted before, and handed it to Qin Feng.

With molds, it is much easier to make various utensils.

Just put the slightly soft glass into the mold, squeeze it hard, and wait for the glass inside to cool down, then it can be demoulded, and at most it will go through a polishing process.

This process is very simple, even an old lady who has never done anything can easily handle it.

So Qin Feng also asked Wei Quanyou to make molds for various glass daily necessities while making these experimental vessel molds.

Compared with the most commonly used pottery in people's daily life, glass products have great competitiveness.

The first is that production is relatively simple.

In the process of making pottery, it needs to go through a series of processes such as soil preparation, shaping, air drying, and baking. Even after it is formed, if it is to be beautiful and easy to use, it also needs to go through a process of glazing.

But glass products are different. As long as the molten glass is put into the mold and squeezed to shape, excellent glass products can be obtained, and they look beautiful.

In addition, the hardness of glass is harder than that of ceramics, and the shortcomings of hardness and brittleness can also be solved by thickening, but ceramics cannot.

Because the internal texture is uneven, if the ceramic is too thick, it is very likely that one side will be full of cracks and the other side can still be used normally.

It is no exaggeration to say that, except for antiques, glass can easily beat ceramics in almost all directions.

Wan Kunming also brought back the saltpeter that Qin Feng needed, and a large amount of saltpeter went into the city and sent to Qin Feng's home.

It takes about four or five hours for glassware to go from mold closing to demoulding.

After preparing all the necessary things, Qin Feng transported them to an open place outside Heixi City.

Although he will try his best to reduce the various harmful gases that may appear during his experiment.

Reduction does not mean elimination. If the operation is not done properly, harmful gas overflow will still occur.

The entire refining process was rehearsed in Qin Feng's mind. The three major raw materials needed to produce mercury fulminate are first mercury nitrate, followed by ethanol, and concentrated nitric acid.

However, the production of mercury nitrate is obtained through the reaction of nitric acid and mercury, so concentrated nitric acid does not need to be produced separately.

But this does not mean that there is no difficulty in producing nitric acid.

Although Qin Feng knows the principle of making these things, Qin Feng doesn't know what kind of preparation equipment is commonly used in chemical industry.

Even if he knew it, he couldn't get it.

So he can only make some equipment according to his imagination.

The first step in the whole experiment is dry distillation of cinnabar ore, which decomposes cinnabar ore into mercury and sulfur dioxide.

The so-called dry distillation is distillation without adding water, and the substances in the distillation chamber are changed in a high-temperature environment.

The whole set of dry distillation equipment is an earthen stove built by Qin Feng with red bricks and clay. Inside is an iron cauldron. There are several layers in the middle, and each layer can hold some cinnabar ore. Come.

There is an external pipe on the top and bottom of the iron pot, which is connected to a glass refrigerator.

It was a huge square glass box with a glass tube passing through it, and water could be filled into the glass box as a coolant, and there was an opening on the side, which was blocked with a wooden plug, and the water could be changed at any time.

There is a blower at this end of the iron pot, which can blow fresh air into the inside of the iron pot, but the iron pot itself is close to being completely sealed.

The pipes coming out of the iron pot are used to cool down the gas. As for the mercury obtained after refining, it can be directly dropped into the water container through the pipes under the iron pot.

At the other end of the glass pipe is connected a huge glass barrel with a lid on it, but there is a gap to prevent the internal pressure from being too high and causing the container to burst.

After setting up the whole equipment, Qin Feng made complete preparations and started the production process of mercury fulminate.

Of course, this is Qin Feng's first attempt at a chemical experiment since he came to another world. Although he has rehearsed many times in advance in his mind, he still can't guarantee that he will be successful.

However, his mentality was not affected by it.

As the saying goes, everything is difficult at the beginning, as long as he can understand the principle, he does not believe that he will not be able to do things.

The flame in the stove began to burn fiercely. In the iron pot, Qin Feng layered the crushed cinnabar ore gravel on the fine grate.

After the mercury is decomposed, it can flow down from the gap in the grate, and finally flow into the container along the glass pipe below.

Ling Chong on the side was also standing next to the blower. Although he didn't know what Qin Feng was going to do with such a big battle, he knew that Qin Feng must have his reasons for doing so.

The little princess moved a small bench and sat beside Qin Feng, looking curiously at the strange things in front of her.

As the temperature in the iron pot gradually increased, Ling Chong also began to continuously inject fresh air into the iron pot.

A faint pungent smell gradually appeared in the air, which belonged to the smell of sulfur dioxide.

In the glass pipe above the iron pot, although sulfur dioxide gas cannot be seen, water bubbles can gradually be seen in the water tank at the end.

The water tank was bubbling and bubbling, because the sulfur in the mercury sulfide was oxidized and turned into sulfur dioxide.

And in the pipe at the lower end of the iron pot, there was actually a drop of silver liquid rolling out. The little princess at the side didn't think there was anything at first, but seeing this scene, her eyes widened immediately.

"This...how is this possible? You actually refined silver?"

Her tone was full of shock, not daring to see the sight in front of her.

But seeing her making a fuss, Qin Feng couldn't help laughing: "Hahaha, what kind of money is this?"

However, the color of mercury is very similar to silver, so it is not surprising that people would mistake it.

Qin Feng didn't explain, but just stared at the mercury in the glass beaker and the blisters in the water tank.

The most ideal state now is that sulfur dioxide can be completely dissolved in water, and the gas escaping from the water tank is only the rest of the gas in the air.

Under Qin Feng's command, Ling Chong, who was pulling the bellows, accelerated or decelerated from time to time, controlling the amount of air injected into the iron pot.
