Luo Youde, he is a very important part of Hong Tao's plan, but Hong Tao has not yet figured out how to get along with him, the son of an official eunuch. It's obviously not a good time to pull him in, he is not a simple and upright Tan family, and there is no shortage of Hong Tao's broken fish and shrimp. He is a businessman, and businessmen pay attention to the exchange of interests, and he really can't come up with any equal benefits to negotiate terms with him at present. But it's not a matter to hang him like this, Corporal Lixian always has needs, you must at least give people a hope, otherwise people are full of food, just to listen to the fresh stories of Australia can accompany you every day? There will be a day when you get bored.

"Brother Hong! Today is your big day, for my brother I am also a person full of copper smell, this load of pickled things also hope that Brother Hong will not refuse, of which 120 is my redemption of the car and ship, and the remaining 100 is a small gift. When Hong Tao ran to the Zhenzhou dock in person, he still saw Luo Youde and Luo Dacai, not even a servant, but two large bamboo baskets covered with red silk cloth beside him, according to him, they should be full of copper coins!

"Brother Luo...... I said that we should not be Brother Luo and Brother Hong, it is too tongue-in-cheek. In my hometown, friends who have a good relationship, the older ones add an old word in front of the surname, and the younger ones add a small word in front of the surname. "Hong Tao is familiar with Luo Youde, and he deliberately talked about that ethereal hometown, and even used Henan dialect.

"Xiao Hong...... It's a bit like the lady in the green building, it's still Brother Hong, let's call each other. Luo Youde tried to call Hong Tao, not only did he think it was not good, but even Hong Tao himself felt that it was not appropriate.

"Okay, each to his own, get on the boat first, and we'll talk as we go!" Hong Tao helped Luo Dacai carry the two bamboo baskets to the boat, Zhen Nima Shen, it is said that some sea ships in the Song Dynasty used copper coins as ballast objects. Gold and silver were not in circulation in the Song Dynasty, except for copper coins and banknotes, bulk transactions often took the way of bartering, or with something called guanzi, a bit like the bills of exchange in later generations, but not the whole country, if you want to go anywhere you can use, take it out and spend it, you can only carry a bunch of copper coins on your back.

"Lao Luo, you have helped me with money many times, and you have indeed identified my weaknesses, and I am now very short of money. However, this method can't be used often, and after a long time, there will be a gap between the two of us, maybe it's because I'm awkward, or maybe it's because you're unbalanced. So, let's put the gentleman first and then the villain, if there is anything, just say it directly, and I'm more comfortable getting along in the way of talking about business. After the business is over, how about we talk about feelings again? Hong Tao sat at the stern of the boat and controlled the sails, while kicking a basket of copper coins in the cabin, and directly picked up the words, so that he found excuses to send money to himself again and again, without asking the other party's purpose, Hong Tao was very unsteady.

"Sure enough, Brother Hong, like me, is a businessman, so I am relieved. Brother Wei didn't ask for anything else, he just wanted to do glass business with Brother Hong, didn't Brother Hong say that he would burn glass on the ship? Luo Youde was not surprised that Hong Tao asked so bluntly, and he did not hide it, and directly put forward his own request.

"Glass? Hey, what am I supposed to be, woe from my mouth...... To be honest, I can only say that I know how to fire a little, but I have never practiced it, and I am not completely sure whether I can burn the kind of colorless glass that Lao Luo said. Hong Tao patted his head, it is cost-effective Luo Youde has taken a fancy to the glass thing, this is really bragging, when did he burn the glass, knowing and being able to do it are completely two different concepts, Hong Tao also knows how the aircraft carrier does it, but he will never do it.

"How sure are you?" Luo Youde was not disappointed, but more attentive. In his opinion, glass should be the same as the best pearls, not every pearl is in the pearl, so easy to fire, and precious fart.

"Well...... Fifty to eighty percent grasp, mainly depending on whether the raw materials are suitable or not. Hong Tao tried his best to recall the raw materials in the firing glass test he did when he was in college in his previous life, and felt that it was still difficult. At that time, I went to the factory for an internship, and the master taught me by hand, and I didn't study seriously at that time, and there were not too many specific operation links that I could remember.

Besides, the glass production methods used in the factory are more advanced processes in later generations, and who has nothing to teach interns to produce glass by soil methods, those processes are not possible at all in this era. And at that time, all the finished chemical raw materials were used, and he didn't know how to find substitutes for many things in this era, and the proportion of raw materials had to be constantly experimented, which was very troublesome.

"Can you tell me what ingredients you need?" Luo Youde's breathing was a little short, in his opinion, glass is a precious treasure, and he is already a master craftsman if he can make one piece a year, but Hong Tao actually said that he is five to eighty percent sure, which is also too scary.

"Soda ash...... Forget it, it's still miscanthus salt, if it's convenient, alkali and miscanthus nitrate can be made, and quartz, quartz we have in the Song Dynasty, right? Hong Tao pondered, the Song Dynasty didn't seem to have the technology of three acids and two alkalis, and the soda ash didn't know how to get it out, so it was replaced by miscanthus salt, and some sawdust was added as a reducing agent.

However, there should be soda in the Song Dynasty, which is the kind of alkali block naturally formed from the salt lake, although it is not soda ash, but it will be more or less reliable. As for where this trona is produced, Hong Tao is not clear, only knows that there are more of these things in the north, but unfortunately now those places are occupied by the Jin Kingdom and the Xixia Kingdom, whether Luo Youde has the ability to get it is still a problem, if he can really get it, he may be able to make soda ash, in that case, firing glass should be a little reliable. Of course, if you can't get it, then don't blame me for not being able to fire colorless glass, it's not that we don't have the ability to burn, but you don't have the ability to make raw materials.

"Shining stone?" Luo Youde wasn't sure if the quartz Hong Tao was talking about was the quartz of the Great Song Dynasty.

"Yes, but don't get the crystal, it doesn't have to be so good, and it's a loss to burn the glass with crystal!" Hong Tao felt that what he and Luo Youde were talking about should be a kind of thing, so for the sake of insurance, he still had to give a little more advice.

"That's all?" Luo Youde seems to think it's too simple.

"The rest is a secret formula, I'll make it myself!" Hong Tao pointed to his head.

"Oh, it's for my brother to be abrupt, abrupt, don't blame!" Luo Youde seemed to understand something, and quickly apologized, and it was very unseemly to ask others about the secret recipe.
