Chapter 149 (2/2)

After these things are hammered, they are put out in the sun. Fortunately, although it was cold in those two days, the sun was good, so it was easy to dry.

After drying, these things are added with flammable spices such as sodium nitrate, rosin and sulfur, and finally twisted into ropes and stuffed into bamboo tubes.

Point and then close the lid. When you open the lid, you don't need to blow at all. Just shake it and the fire will come out.

This kind of high-grade origami is much longer than those of low-grade origami, and it only needs a flash to ignite the fire. After all, the sulfur, sodium nitrate, rosin and other things added in this high-grade folding fold are extremely flammable. As long as there is a little oxygen, it can burn immediately.

The stone bear has seen a lot of orifices. In his museum, there are some orifices used by several wealthy families in the Song Dynasty. One of them was used by a prince.

As a cultural protection expert, Shi Xiong naturally knows how to make and use the origami, so before going out, he started to make some origami.

Since we want to do it, we must do that kind of high-end folding. The tribe itself has reed velvet collected in autumn and rosin collected from the trunks of long leaved pine trees in the mountains. The best rosin is produced from Pinus sylvestris, while a large number of Pinus sylvestris grow in the southeast of the new world. We don't know how many Pinus sylvestris grow on Dawu Mountain alone.

Rosin is very useful in the tribe, so there is a lot of rosin in the tribe.

As for nitrates and sulfur, a large quantity of them were seized from the French this time. It is enough to make gunpowder, let alone pyrotechnics.

And sweet potato vines, there are many of them, and they are all dried in the sun. It's enough to pick them up. The only thing missing is cotton, but it's hard for the stone bear.

Lieutenant Ferguson has a cotton padded jacket, so Shi Xiong directly changed a beaver fur coat for Lieutenant Ferguson's broken cotton padded jacket. After taking it apart, there was enough cotton inside

As for the bamboo tube used for folding, there are many bamboo tubes on Dawu Mountain, which are enough.

Speaking of bamboo, there was no bamboo in Dawu Mountain, but after the Cherokee moved south and contacted the Pueblo people, they introduced some bamboo from Pueblo people, so there was bamboo in Dawu Mountain.

However, in order to prevent the bamboo tube from being damaged by the smoldering fire, the stone bear rolled the thin iron sheet into a barrel and lined it in the bamboo tube, and then inserted the made fire rope into it, and a fire fold was made.

It shocked the whole tribe immediately after it was made. Even Lieutenant Ferguson was shocked by this kind of ”spontaneous combustion” with one wave. You know, at this time, although Brandt, a German, had extracted white phosphorus from his urine and made the most primitive white phosphorus match with white phosphorus stained with sulfur, this kind of match did not spread because it was too dangerous and could spontaneously ignite at a little higher temperature, which burned a lot of people.

As for the real safety match, it will take almost 100 years before it is developed by the Swedish Lundstrom.

So in Europe of this era, this kind of thing that can ”catch fire” by itself is absolutely rare
