Abandoned woman from a poor family, she is addicted to wealth

Chapter 196 Calligraphy Water Writing Cloth

"Then you have to keep it secret for me." Lu Jiu said solemnly, "I still need to rely on this artifact to make money."

Fu Lanqing: "..." Beauty is nothing but money.

He was still quite curious, and nodded obediently: "Don't tell others, and A Yuan won't tell either, so keep it secret for you."

Lu Jiu patted him on the shoulder: "Very enlightened!"

Then, let Fu Lanqing prepare a lot of things.

In fact, it was nothing, just prepared a lot of black cloth for Lu Jiu to experiment with.

Water writing cloth is mainly made of cloth, which is made according to the principle that paint is transparent when it meets water.

Using black cloth as the medium, add a layer of environmentally friendly white paint that has been treated with a special process on its surface. The paint has the effect of being transparent when exposed to water.The main component of the paint is silica, which is the main component of sand and the main raw material of glass.

Water transparency is mainly the physical principle of light reflection.

Because Lu Jiu will open a workshop to make glass in the future, Fu Lanqing can't let Fu Lanqing know about the method of refining silica.

He is so smart!
Lu Jiu directly bought a bottle of paint specially used to make water writing cloth in the system mall.

Now she is mainly experimenting with the kind of ancient cloth that is most suitable for water writing cloth.

Fu Lanqing moved quickly, and got a lot of black cloth for Lu Jiu.

"Which absorbs water better?"

Fu Lanqing didn't understand either, but Xiu Niang did.

The embroiderer pointed to some of the fabrics.

Lu Jiu planned to start experimenting with these pieces of fabric, because the paint was limited, so Lu Jiu only painted a small piece of each piece.

The current sun is not bad, wait for more than an hour, and it will almost be ready for use.

(PS: On a certain degree, there are some messy manufacturer advertisements about how to make water writing cloth, and there are few practical ones, so the little brother wrote according to his own ideas. If there is a cutie who knows how to do it, you can be friendly in the book review area Proposed, the little brother will change it at that time, bow and thank you!)
It was impossible for Lu Jiu to wait for more than an hour, so he simply continued to learn how to read and write with Fu Lanqing.

Writing is too wasteful of paper, Lu Jiu refused.

Although it is not your own thing, it is really shameful to waste it.

Today, he is also a good person with straight views.

Qian Qian: "..." You can let the good guy go QAQ!

Lu Jiu's way of recognizing characters is very simple and rude. He picks up a book and starts to read it. He even reads it to Fu Lanqing. Nine deepens the impression.

At this moment, Lu Jiu really admitted that Fu Lanqing was a god of learning!
The word "xueba" has stained him on him. He knows astronomy at the top and geography at the bottom. He knows everything and knows everything.

I really don't know how a sick person can understand so much.

More than an hour passed quickly, and Lu Jiu drank a lot of tea, so her throat was not so dry.

Lu Jiu took the cloth back to the room, then took out an unused pen, dipped it in the water, and wrote on the cloth.

A miracle happened again!
Really left a mark.

Fu Lanqing's eyes widened in surprise.

But Lu Jiu frowned a little dissatisfied, and threw the piece of fabric aside.

After trying several pieces in a row, Lu Jiu only left two pieces of fabric in the end.

Fu Lanqing took a look and found that the two pieces of fabric were not so smudged, just like writing on rice paper.

Lu Jiu was still thinking, and Fu Lanqing waited obediently.
