"Living at the hill, I dig a hole to plant pumpkins, dig a golden lump... dig a silver lump... dig a copper lump... Laikma..."

Zhao Qi hummed a small song, and dug out a toad full of lumps with his hoe, staring at Zhao Qi innocently with his big eyes.

"What are you looking at?" Zhao Qi kicked the toad away and continued to dig.

"Bang~"

With a crisp sound, the hoe turned up a stone, and the broken places reflected colorful light in the sun.

I'm going, have you really dug up the baby?

Zhao Qi excitedly threw down the hoe and picked up the stone. It was about the size of a fist, heavy, and the broken place had a crystal clear feeling. After he got it to the pond to clean it, his heart felt so thumping that he couldn't hold it.

This is a piece of crystal, but it is not pure. A piece of yellow impurity in the middle looks like shit, but Zhao Qi was extremely excited. Crystal, no matter what the appearance is, this piece has to be sold for one or two hundred yuan in the past.

Zhao Qi held up the yellow crystal stone and looked at the sunshine over and over, and saliva dripped down the corner of his mouth.

As an antique lover, Crystal Zhao Qi is no stranger to it.

In fact, antiques contain a wide range of content, which has a lot of overlapping fields with what ordinary people say about cultural relics, so they contain a lot of content. High-end calligraphy and painting porcelain, low-end walnut bracelets cover almost all fields such as plant, animal, mineral, industry, and humanities. Some people plate walnut beads, and some people plate ivory and jade are all small paths. Research and collection of porcelain calligraphy and paintings is recognized as a real cultural artist.

Of course, those who dare to touch literary, calligraphy and painting are either rich or noble, and those who are poor cannot afford to play with them.

Even if you can afford it, most of them were done just yesterday. If you take it out, you can only make industry experts sneer.

In the field of collection, crystal is a very special category.

Because there are many types of crystals, hundreds of thousands or millions of expensive ones, but there are also fewer than tens of dollars, the audience and choice range are relatively wide. There are no people who can't afford to play, but only whether they like it or not.

Moreover, because there are many types of crystals, it is not as expensive as it is. These natural minerals are just like those who play with strange stones, just like those who like them.

Of course, good crystals have one common feature, that is, they must not only be crystal clear, but also have their own characteristics.

This feature is the unique colors and structures formed by the different minerals inside.

There are many ancient crystal jewelry, and the Warring States Crystal Cup treasured in the Hangzhou Museum is one of the most famous national treasures.

Zhao Qi also heard of another one. A banana leaf crystal cup from the Northern Song Dynasty unearthed in Nanjing. It has exquisite shape and has caused a sensation in the antique industry.

Moreover, Buddhism flourished during the Tang and Song dynasties, and scholars and officials were also literati and elegant, so there were more crystal items, such as jade bi, handkerchief, Buddhist beads, bracelets, jade pendants, pendants, accessories, etc.

China's crystal collection craze began in the Song Dynasty.

I heard that the pillar axe that Zhao Kuangyin had never left was made of crystal, but was just unofficial history and there was no formal historical record.

The day before Zhao Qi traveled through time, he visited Ashoka Temple near Ningbo. A large amount of crystals were embedded in the pagoda of Ashoka.

However, in ancient times, the scholars and officials who were interested in the pure crystals were all the best. Moreover, because the hardness of the crystal was too high, it was difficult to polish and process, which was far less than that of jade. Therefore, there were very few things passed down from generation to generation, and each piece was a rare fine product.

The crystal stone with a large amount of impurities dug out may not have any value in this era.

After thinking a little, Zhao Qi also made some rough judgments.

But how can there be crystals near this brick kiln? Is there a crystal mine here?

Zhao Qi observed around him with some confusion in excitement.

"Brother, what did you take? It looks so beautiful!" Xiaozhu came back from Grandma Zhang's house and asked around long distances, but after running over and taking a look, he was no longer interested. "This was picked up by Sister Xiaomi and the others at the dock and went to play. It was useless!"

Zhao Qi then realized that crystal was not from this kiln factory, but he asked curiously: "Are you saying there are many such stones on the dock?"

"Well, I heard from Sister Xiaomi that there are many jewelry stores nearby, but I haven't been there before, so I don't know where it is!" Xiaozhu nodded.

"Why are you so few when you go there?" Zhao Qi asked.

"Because I want to take care of my brother, you like to run around, so you can only follow closely. And the grandmother also asked me to stop you from going to the dock to play, for fear of falling into the sea!" Xiaozhu stuck out her tongue and looked at Zhao Qi secretly, "Brother likes such stones. Another day, Sister Xiaomi and I will go to the dock to help you pick up more."

"Well, we'll go together in a few days!" Zhao Qi felt a little uncomfortable when he touched the dried and yellow bamboo's hair, which was combed neatly. It was only four or five miles away from the harbor, and the little girl hadn't been there for five or six years.

"Okay, Sister Xiaomi said there are so many boats on the pier and there are many people, which is very lively!" Xiaozhu applauded happily.

Xiaozhu's words also made Zhao Qi feel confident that this crystal stone with too many impurities was not valuable in the current Song Dynasty, otherwise it would not have been thrown into children's toys by the jewelry store.

However, for Zhao Qi, these stones are of great use.

There is no problem with making glass of various colors.

Glass appeared in many poems and historical records of the Tang and Song dynasties, and glass also appeared in some calligraphy and paintings. Zhao Qi clearly remembers that some ancient paintings of the Song Dynasty used glass bottles to arrange flowers and raise fish.

However, during the Tang and Song dynasties, glass and glazed were confused, but in fact, the composition and technology of glass and glazed were very different. The main component of glazed was barium lead salt crystallization, with low melting temperature, while glass was mainly calcium and sodium silicates, with high melting temperature, and the color of glass was rich in burning, with complex process and poor transparency, but glass had much purer colors.

However, whether it is glass or glass, they were very precious items in ancient times, and they were not affordable to be bought by wealthy families. In the collection world that Zhao Qi is familiar with, the collection of ancient glass cultural relics is of great value and is highly sought after by cultural and entertainment enthusiasts. However, due to their small quantity and fragility, the number of existences is extremely rare and the price remains high.

Although there is glass in the Song Dynasty, good glass is said to be shipped from the Great Food Kingdom, namely Iran and the Arabian Peninsula.
