Princess Dangli's words left Liu Tan completely bewildered. He looked up at Princess Dangli and asked, "Mass...mass grave?"

Seeing his expression of ignorance, Princess Dangli also said, "Yes, a mass grave. What? You didn't know? Did your servants do it without telling you?"

Princess Li's expression changed as she spoke, and she looked as if she was going to clean up the mess for Liu Tan.

Liu Tan had been wondering if someone was doing something illegal behind his back, but luckily, his memory hadn't faded. He remembered what he'd done before, and quickly said, "It's okay, I'll let them know. Thanks for letting me know, sister."

Princess Dangli looked at him with some doubt: "Are you really okay?"

Liu Tan nodded frantically: "It's really okay, sister, don't worry."

Princess Dangli did not ask any more questions. She and Liu Tan had only become a little closer recently, and it was not easy for her to meddle in many things. However, she had made up her mind that if she heard of anyone doing this again, she would find a way to deal with it.

After Princess Li left, Liu Tan quickly called Bi Gao over and asked, "Where did you send someone to find the bones?"

Bigao said carefully, "Your Highness, not many people have died recently, and even fewer have been free from care. If Your Highness wants the bones, you can only..."

“Stop, stop, stop!” Liu Tan was almost going crazy: “Who said we wanted human bones?”

Bi Gao was stunned for a moment, then realized that he seemed to have misunderstood something, and hurriedly asked, "What kind of bones does Your Highness want?"

Liu Tan glared. "It doesn't matter what animal's bones, just bones. No human bones!"

Bi Gao rarely saw Liu Tan so emotional, so he quickly said, "Yes, I'll give the order right away. It's my fault, Your Highness, please don't be angry."

Liu Tan waved his hand and said, "I don't blame you, go!"

Bi Gao hurried out to give orders, while Liu Tan... Liu Tan sat there feeling sick.

Fortunately, we haven’t started firing bone china yet, otherwise human ashes would be burned in it without his knowledge, and then he would use it as tableware... I’d feel like vomiting every minute.

The most important thing is that Liu Tan now has a psychological trauma when he hears about bone china.

But since we have to do it, we naturally have to continue.

This time the ashes, ah, the bone char, arrived very quickly.

Originally, Liu Tan would personally watch over the work even if he didn't get to work himself. He didn't like playing with mud, but he really liked the process of building something from nothing and enjoying the joy of the moment of success.

However, this time he was unable to get through and just ordered his subordinates to conduct the experiment.

However, although he said it was an experiment, he did not really let the craftsmen do it, but gave a certain proportion that must not be less than 20%. That is to say, out of 100% of the raw materials, at least 20% is bone charcoal and the other 80% is clay.

So the craftsmen tried each one from 20% to 30% and then to 35%.

There is no way to avoid this half. After adding 40%, the adhesion of the clay will have some problems and it basically cannot be shaped. Even if it is reduced to 35%, it can only be barely shaped. If it is more, it will really not work.

Among these experimental species, the sources of bone charcoal were also separated. After the experience with human bones, Bi Gao was very efficient and found many different kinds of bones, mainly chicken, duck, pig, cow and sheep bones.

Liu Tan directly excluded other bones because they were uncommon, so in addition to different proportions, each proportion was used as a test sample according to different bone charcoal.

Fortunately, Liu Tan's palace was large enough and had a small population, so there was enough space for him to work. As these test pieces were waiting to be fired, they filled up the entire yard.

The firing process lasted two or three days.

Seeing that time was running out, Liu Tan thought that if it really didn't work, he would have to give up and let the craftsmen fire ordinary celadon first.

New Year’s gift, New Year’s gift, how can it be called a New Year’s gift if you give it after the New Year’s Day?

Fortunately, this batch of experimental products was finally produced before the deadline he set.

But he was not very satisfied with the final product.

The light transmittance was very different from what he had imagined, and it felt like something was missing. Of course, it was much better than the original celadon.

However, celadon has its own beauty, and Liu Tan has no intention of giving up on it.

To make bone china thin, craftsmen need to be extremely patient and careful, and it also needs to be fired twice, which is time-consuming and labor-intensive. Before the craftsmen in this industry reach a certain scale or assembly line production becomes possible, bone china will not be a common household item.

Since it is impossible, then let it become a rare existence. Celadon is the main product that Liu Tan wants to promote to the public. Bone china is used to cheat people out of money, no, to make money.

Among this batch of bone china, the one with the best light transmittance is probably made from cow bone powder.

The others are all lacking something. Liu Tan suspects that it may be related to the different element content of each animal's bones, and cattle bones have the highest content in a certain aspect, so the molding effect is good.

As for what exactly it is, Liu Tan said he didn't know. After all, he was just a liberal arts student. At most, he liked to read some extracurricular books, but he was not a researcher!

After determining that ox bone was the best bone china and deciding to use ox bone, Miao Rui came over and asked, "Your Highness, what should we do with the remaining ones?"

Liu Tan: ...

He felt a little melancholy. According to his marketing strategy, this batch must be smashed directly. After all, they were just prototypes. It was impossible to sell them to others if the quality was not good, not to mention that the shape of these prototypes was not particularly good.

However, it was a pity to smash it, because it reminded him of the secret color porcelain. It is said that many unqualified products of the secret color porcelain were smashed in the past. Later, the formula of the secret color porcelain was lost. Until the discovery of the underground palace of Famen Temple, the secret color porcelain was basically in legend.

Later, after the discovery in the underground palace of Famen Temple, everyone saw how beautiful the secret color porcelain was.

But it was only a moment of melancholy, and Liu Tan decided: "Smash it!"

Secret color porcelain is overly precious because the formula has been lost, but how could Liu Tan let the formula of bone china be lost?

No matter how precious bone china is, he just wants to price it a little higher. If he wants to distinguish between nobles and commoners, he can just use the shape and pattern.

As long as there are enough bone china handed down from generation to generation and the recipe is not lost, these failed products can be smashed.

After determining the formula of bone china, the next step is the shape and secondary firing. Because bone china is too difficult to shape, Liu Tan decided not to make those fancy shapes, but to follow those commonly used by Liu Che and Chen Ajiao. At most, some beautiful patterns can be drawn during the glaze firing, and then gold can be painted on the edges of the tableware. Even the patterns can be gilded, depending on which one looks good.

However, when Liu Tan was eager to determine the color, he discovered something very important that he had overlooked before: the colors of pigments these days are very rare!

Liu Tan: I suddenly had a bad feeling.
