Chapter 120: Simple thermometer

  Whether it is making wine or making koji, the control of temperature and humidity is very important, especially temperature.

   When I used to make koji at home, I had a thermometer, so I don’t have to worry about temperature control. But where is there such a thing as a thermometer in the Gaoshu tribe? The feeling of temperature here is entirely based on the body sensation, and the standard for judging the temperature is three-cold, hot and not cold or hot, very comfortable...

   Therefore, it is very necessary to make a few simple thermometers.

   This kind of simple thermometer is very easy to make. As an associate researcher-level senior intellectual, if the simple thermometer can't do it, he will be blinded for more than ten years of schooling.

   In fact, Shi Xiong used to make a simple thermometer for his nephew in his previous life. At that time, in order to arouse children's interest in some physical phenomena, he made a simple thermometer. The consumable is a small bottle with a cap for penicillin, a plastic straw and some red ink.

   As for time-consuming, more than twenty minutes!

   Sure enough, that little simple thermometer made my nephew very interested, and Shi Xiong, who was an uncle, also had a sense of accomplishment.

   But it was easy to make a simple thermometer at that time, because all kinds of materials were easy to find, but in the Gaoshu tribe, there were no glass bottles or plastic straws, so I had to get these things.

   If a real thermometer had been in a previous life, it could be made with a variety of tools, stone bears, but in this age, only this kind of simple thermometer can be made.

   A small glass bottle and a thin glass tube can make a simple thermometer. But the question is where can I find glass bottles and thin glass tubes?

   "Does I have to burn glass in order to make a few simple thermometers?" Shi Xiong held his forehead and thought, "But the problem is that although you know the raw materials for glass burning, you really haven't burnt glass."

   shook his head, Shi Xiong's gaze fell on the bottle of whiskey.

"Yes, there must be some glass products traded from Waxichu in the tribe. Although the transparency is not good and the color is not very beautiful, it can be used to blow a few small glass bottles and a few thin glass tubes after melting. It shouldn't be a problem!"

   Blowing glass bottles and blowing thin glass tubes, this living rock bear did it several times when he was doing experiments in high school.

   At that time, the high school chemistry teacher who was almost 60 years old, Mr. Wu, was a **** in the school, because almost all the glass laboratory equipment in the school was made by the chemistry teacher himself.

   Ishikuma was in the town when he was in high school. In the late 1990s, the funding for education in mountain towns was very tight. When taking chemistry classes, students rarely had the opportunity to do experiments on their own.

   As an excellent chemistry teacher, in order to allow students to do more experiments, Mr. Wu makes a lot of glass laboratory equipment every year. It is said that Mr. Wu worked as a glassmaker in the county glass factory for a period of time in that buzzing age, so he has a lot of experience in the firing of some glass, including experimental equipment made of borosilicate glass.

   Ishikuma liked to do chemistry experiments when he was in high school, and his grades were relatively good, so Mr. Wu also let Ishikuma try to blow some experimental equipment such as flasks and thin glass tubes.

   Although it has been a long time since, the memory is still deeply imprinted in Shi Xiong's mind.

  I don’t know how to burn the glass stone bear, but there are ready-made glass products in the tribe, as long as they are broken, melted, and then blown.

   There are ready-made crucibles. The crucible that can melt iron into molten iron is absolutely no problem for melting glass.

  The worst is a thin iron pipe, this is also simple, the big deal is to cast a small diameter thin iron pipe.

   Just do it.

   Ishikuma pondered it over, and when he felt that there was nothing wrong with what he had on hand, let's do it!

  Ferguson and the others can cast a thin iron pipe, and they are willing to do it. After all, every time casting something is an improvement for them, whether it is Ferguson, hard bones, rabbit mouths like to do it.

   So Shixiong gave this to Lieutenant Ferguson. The requirements were not high. The thickness of the thin iron pipe wall was not required, but the inner diameter could not be greater than five millimeters and the length could not be less than 1.2 meters.

   Such a fine-caliber iron pipe was more difficult for Ferguson and the others, but they still took the task very happily.

   Then Shi Xiong found Li Lei and asked him to collect some glassware from the tribe.

   For this strange request, Li Lei didn't dare to refute it, so he readily agreed.

   So, early the next morning, Shi Xiong got three wine bottles, two glass vases, and a qualified thin iron pipe.

  With these things, Shi Xiong did not hesitate to prepare to fire the glass.

The hard bones and bunny mouths following Ferguson~www.wuxiaspot.com~ Kuai Ma, Hong Yun and the ladies of the tribe who followed the Stone Bear. Seeing Master Guardian raise the hammer without hesitation, "crack!" "The three wine bottles and two glass vases were smashed, and the corners of their distressed lips twitched.

  Glass is nothing to Shi Xiong, he knows the value of this thing is not high. It is also not a good thing for Ferguson, after all, in this era, the penetration rate of glass in Europe is also relatively high.

   But glassware is still extremely precious to the Indians of this age. Such a wine bottle can be worth a piece of bison leather!

   Seeing Master Guardian smash these precious glassware like trash, it is a strange thing if they don't feel sorry for it.

"Don't feel bad about these glasses, this thing is not worth money." Shi Xiong looked up at the tribesmen who were all faceted and smiled and explained, "This thing is actually sand plus some other worthless things. It is fired, and it is not too difficult. It is much worse than steel making. If you like it, when I finish the work at hand, I will teach you how to burn glass. When you burn a pot of glass, you will know this. The real value of the gadget."

   Talking, Shi Xiong picked up the last complete wine bottle. This is a wine bottle containing fruit wine. I don't know who drank the wine clean, but the bottle has been kept for a long time.

   "Have you seen this bottle? We can exchange at least one hundred such bottles for a single bison leather! So, this thing is really worthless!"

   said, Shi Xiong raised the hammer in his hand and directly smashed the last bottle.

   Then Shi Xiong put down the hammer, picked up the small broom and swept all these glass ballasts into the crucible, and started to ignite and melt the glass.
