Shixiong regretted it a bit after saying the arsenic.

　　 As a schoolmaster in his previous life, he certainly knows how to prepare arsenic, and he also knows that arsenic and Glauber's salt are the best decolorizer for glass.

　　 But the problem is that Glauber's salt is easy to find, and some of it is readily available in the tribe, but arsenic is not easy to handle.

Although there are many arsenic in nature, most of them exist as sulfides or oxides. For example, realgar is tetraarsenic tetrasulfide, orpiment is arsenic trisulfide, and arsenic is arsenic trioxide.

　　 Whether it is realgar, orpiment or arsenic, there are many at present. The first two can be found in nature, and the latter can be obtained by heating realgar.

　　 But this elemental arsenic is not so easy to refine. It is not that elemental arsenic is difficult to extract. On the contrary, elemental arsenic is very easy to extract, but the problem is that many highly toxic substances are produced during the refining process. If you are not careful, it is easy to be poisoned in the process of extracting elemental arsenic.

　　 Seeing his boss suddenly fell into a kind of weird contemplation, Agustaugust hesitated for a long time before carefully whispering: "Boss, boss..."

Agusta's cries awakened Shi Xiong from his contemplation, and he said with an apologetic smile: "Let, I'm sorry, I suddenly remembered something." As he said, Shi Xiong waved his hand again. Let’s not consider arsenic for the time being. Although using arsenic as a decolorizing agent is very good, this thing is poisonous, and if one is not careful, it is easy to be poisoned. So I just thought about not using this."

　　 "Boss, I'm not afraid of poisons, I can take care of it..." As soon as the boss said that arsenic was not needed, Agust became anxious at first.

Shi Xiong waved his hand to interrupt Agust’s words very simply, and then said very seriously: "Let, I know you are very interested in a new substance, but you have to understand that if you are interested, we can get it slowly in the future. , But you can’t make things like that just because you’re interested. In my eyes, your health is more important than anything else.”

　　'S words flashed an inexplicable brilliance in the eyes of the four alchemists, but Agustadays still wanted to argue that the stone bear stopped him.

　　 "Let, tell you the truth, just now I said that using arsenic as a decolorizing agent is a very irresponsible argument. You are more proficient in medicine. You naturally know the toxicity of arsenic, right?"

　　 Agusta nodded. Before the more toxic cyanide appeared, the arsenic, which can be easily prepared, was the most popular poison in Europe.ァ新ヤ~⑧~1~中文网ωωω.χ~⒏~1zщ.còм

　　 "Arsenic is the main component of arsenic, but arsenic exists in the form of sulfides and oxides in nature. You should know realgar, right?"

　　 Agustatrix nodded again. Although he didn't know exactly what sulfide and oxide meant, he knew that Stone Bear would not fool him.

"Realgar is arsenic sulfide, and it is the most common arsenic sulfide in nature. Realgar can form orpiment when exposed to the sun, and if the realgar is heated, it will emit white smoke with a smell of garlic. This white smoke is arsenic, which is the oxide of arsenic. You should know all of this, right?"

　　 "I know that heating realgar can get arsenic, and also know that realgar can get orpiment when exposed to the sun. Whether orpiment or arsenic is very poisonous." Agusta answered honestly.

　　Although the other three alchemists did not understand medicine, they had also heard of the famous arsenic. They naturally stayed away from this highly toxic substance.

Shi Xiong smiled slightly, "Whether it is realgar, orpiment, or arsenic, it is very easy to obtain, but the elemental arsenic in it is difficult to extract. And even if it can be extracted, it is easy to produce highly toxic substances during the extraction process. , You will be poisoned if you are not careful. I don't want to cause you to be poisoned by refining elemental arsenic. Let, do you understand what I mean?"

　　 "Boss, but I can extract arsenic, I know how to extract it, and as long as I pay attention, it will not be poisoned."

　　 Shixiong smiled slightly and waved his hand again: "I know you can extract arsenic, and I also know, don't you just heat soap and orpiment together?" New 81 Chinese website update the fastest mobile terminal: https:/

　　 Agusta had seen a ghost expression on his face, "Boss, how do you know this method?"

"Hehe, why don't I know this method? The German alchemist Albert Magnus used this method to extract elemental arsenic from arsenic compounds more than 500 years ago. This method is used by your alchemists. It has been circulating in China for a long time."

　　 Agusta nodded and admitted, but he still had an unbelievable look in his eyes when he looked at the stone bear.

"Well, don’t explore how I knew it. I can only tell you that I know almost everything you know, and I know a lot of things you don’t know. Well, let’s refine the matter of elemental arsenic. Stop here, let’s not talk about it anymore. Considering your health and safety, the four of you are forbidden to fiddle with these highly toxic things in the future. I don’t want to just save you from **** and you will give yourself to yourself. Playing to death."

　　The three other alchemists except Agusta laughed, but Agusta still had a gloomy expression.

Shi Xiong knows why he is upset. The alchemists of this era are of this virtue~lightnovelpub.net~ It feels like there is a big pile of gold in front of you. You only need to take a step to get to this gold, but It happened that this tuft of gold was enclosed in an indestructible bulletproof glass cabinet...

　　 "Alright, let's not be sullen. The decolorizer is not only arsenic, we can also replace it with other things."

　　 "Huh? Boss, is there anything better than arsenic?"

　　 Shixiong shook his head and said: "Replace arsenic with other things, the effect will naturally not be so good, but it is definitely enough. Glauber's salt knows, right?"

　　 "Know, don't we have a lot of purified thenardite in our tribe? Boss, don't you say that using thenardite can replace arsenic?"

　　 "Replacement cannot be replaced, but with Glauber's salt, the glass you burn out will not be so ugly."

After a pause, Shixiong continued to explain: "In fact, the real chemical decolorizing agent is to add about 2 French pounds of arsenic and about 5 French pounds of Glauber's salt to 100 kilograms of raw glass for burning glass. The mixture of arsenic and Glauber's salt is The best decolorizing agent. But arsenic is not available now. If we only use Glauber's salt, the effect may be worse, but it is not much worse. Even if the burnt glass has different colors, it will definitely not be a lot. Yes, it’s okay to use it as experimental equipment."

　　No matter what decolorizer is used, the fundamental purpose is to replace the iron ions in the glass liquid with high-valent iron compounds, so that the glass will not produce green or blue.

　　 Arsenic is good as a glass decolorizer, but it is not irreplaceable. At least there is Glauber's salt, which can also decolor the glass.
