Chapter 215 (1/2)
The stone bear regretted the arsenic.
In his previous life, as a Xueba, he certainly knew how to prepare arsenic. He also knew that arsenic and mirabilite were the best decolorizing agent for glass.
But the problem is that Glauber's salt is easy to find, and there are some ready-made Glauber's salt in the tribe, but the arsenic is not easy to get.
Although there are a lot of arsenic in nature, most of them exist as sulfides or oxides. For example, realgar is arsenic tetrasulfide, orpiment is arsenic trisulfide, and arsenic is arsenic trioxide.
At present, there are many realgar, orpiment and arsenic. The former two can be found in nature, while the latter can be obtained by heating the realgar.
But the arsenic is not so easy to extract. It's not that it's hard to extract arsenic. On the contrary, it's easy to extract arsenic. But the problem is that a lot of highly toxic substances will be produced in the process of extracting arsenic. If you don't pay attention to it, it's easy to poison people in the process of extracting arsenic.
Seeing that the head of his family suddenly fell into a strange meditation, Agust hesitated for a long time, and then carefully whispered: ”head, head...”
Agust's voice awakened the stone bear from his meditation. With an apologetic smile, he said, ”let me, I'm sorry. I just thought of something.” Then the stone bear waved his hand again, ”let's not consider arsenic for the moment. Although it's good to use arsenic as a decolorizer, it's poisonous. If you don't pay attention to it, it's easy to be poisoned, so I was just thinking about not using it.”
”Boss, I'm not afraid of poison, I can do a good job of protection...” when the boss said that there was no need for arsenic, Agust got worried first.
Stone bear simply waved his hand to interrupt Agust's words, and then very seriously said: ”let me know that you are very interested in a new substance, but you have to understand that if you are interested, we can do it slowly in the future, but you can't do it without being sure because you are interested. In my eyes, your health is more important than anything.”
This made the eyes of the four alchemists flash with an inexplicable brilliance, but Agust still wanted to argue that the stone bear stopped him.
”Let me tell you the truth, just now I said using arsenic as decolorizer is a very irresponsible statement. You are quite proficient in medicine, and naturally you know the toxicity of arsenic? ”
AGUS nodded. Before the more toxic cyanide appeared, arsenic, which can be easily prepared, was the most famous poison in Europe.
”Arsenic is the main component of arsenic, but arsenic exists in the form of sulfide and oxide in nature. You should know realgar, right
Agust nodded again. Although he didn't know exactly what sulfide and oxide meant, he knew the stone bear wouldn't fool him.
Realgar is the sulfide of arsenic, and it is the most common arsenic sulfide in nature. Realgar can form orpiment when exposed to the sun. If realgar is heated, white smoke with garlic odor will appear. This kind of white smoke is arsenic, which is the oxide of arsenic. You should know all this, right
”I know that arsenic can be obtained by heating realgar, and realgar can be obtained by exposing realgar to the sun. Both realgar and arsenic are highly toxic.” Agust's honest answer.
Although the other three alchemists didn't know about medicine, they also heard about the famous arsenic. They naturally kept a distance from this highly toxic substance.
