Chapter 215 (2/2)
Stone bear smile, ”whether realgar or orpiment or arsenic are very good, but the elemental arsenic is very difficult to extract. And even if it can be refined, it is easy to produce highly toxic substances in the process of refining. If you don't pay attention, you will be poisoned. I don't want to poison you because of the extraction of elemental arsenic. Do you understand what I mean? ”
”Chief, but I can extract arsenic. I know how to extract arsenic, and as long as I pay attention, I won't be poisoned.”
With a smile, the stone bear waved his hand again and said, ”I know you can extract arsenic. I also know that it's just to heat soap and orpiment together.”
Agust a face saw ghost's expression, ”boss, how do you know this kind of method?”
”Ha ha, why don't I know this method? More than 500 years ago, German alchemist Albert Magnus used this method to extract elemental arsenic from arsenic compounds. This method has been popular among your alchemists for a long time
Agust nodded, but he still had an incredible look in his eyes.
”Well, don't ask how I know. 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 stop refining arsenic. Let's stop talking about it. In terms of your health and safety, you four are forbidden to tamper with these poisonous things. I don't want you to play yourself to death just after saving you from hell. ”
Except for Agust, the other three alchemists all laughed, but Agust still had a sullen expression.
Stone bear knows why he is not happy. The alchemist of this age is of this virtue. It feels like there is a big lump of gold in front of him. You only need to take a step to get to the gold, but this lump of gold is covered in an indestructible bulletproof glass cabinet
”Well, let's not sulk. Decolorizer is not only arsenic, we can replace it with something else
”Ah? Chief, is there anything better than arsenic? ”
The stone bear shook his head and said, ”it's not so good to replace arsenic with something else, but it's definitely enough. Does mirabilite know? ”
”Yes, there are many purified Mirabilite in our tribe? Chief, do you think mirabilite can replace arsenic? ”
”You can't replace it, but with mirabilite, your glass won't be so ugly.”
After a pause, Shi Xiong continued to explain: ”in fact, the real chemical decolorizer is adding about 2 FA pounds of arsenic and about 5 FA pounds of mirabilite to 100 kilograms of raw materials for burning glass. The mixture of arsenic and mirabilite is the best decolorizer. But now we can't use arsenic. If we only use mirabilite, the effect may be worse, but it's not much worse. Even if there are different colors in the burned glass, there won't be a lot of them. It's no problem to use them as experimental equipment. ”
No matter what kind of decolorizer is used, the fundamental purpose is to replace the iron ions in the liquid glass with high valent iron compounds, so that the glass will not produce green or blue.
Arsenic is a good decolorizer for glass, but it is not irreplaceable. At least mirabilite can decolorize the glass.
