After all, Anthony is a rich boy from the fashion capital, and there is no mystery to him about a luxury in the eyes of ordinary people, such as "glass mirror", and even the latest mirror-making technology is also familiar to him.

"The most popular mirror-making process now was invented by an alchemist named Dalcarlo of the Marquis of Hailan, who coated molten tin foil on the back of the glass to create a very clear mirror, but there was a problem with this process that was difficult to overcome - the tin plating layer could easily fall off."

"Wouldn't it? I have glass mirrors in every room in my house, some of which have been used for years, but I have never seen the tin foil come off. Lyudmila was deeply skeptical.

Anthony glanced at her with disdain, "Your glass mirror tin foil will not fall off, that is because the mirror was blessed by magic before leaving the factory, and the tin foil was forcibly fixed firmly on the smooth mirror surface with the power of magic, but as we all know, if an industrial product cannot get rid of the link of blessing magic, its cost will inevitably remain high, which is why the price of an ordinary glass mirror in the market is so expensive, comparable to the same weight of silver!" ”

Lyudmi tugged at the corners of his mouth, speechless. She once ridiculed Anthony as a "rich second-generation son", which is not entirely true. Anthony is a bit of a son, but he is not a "rich second generation". The history of the Fogel family can be traced back to the time of Friedrich the Great, and has been active in the financial industry of the empire and the aristocratic circle of the upper class for nearly two centuries.

The so-called "rich can not be more than three generations", and only after three generations can you be considered to enter the threshold of the nobles of the family. By this standard, Anthony is of course a noble son, and he has become accustomed to fine clothes and fine food, collecting antique works of art and playing with luxury goods is an indispensable pleasure in the daily life of the aristocracy, and the more he plays, the understanding of art and luxury goods is of course far beyond ordinary people.

In fact, Miss Lyudmila, who is most disgusted with the "rich second generation", never realized that she was more in line with the definition of the "rich second generation" than Anthony: she lost her father when she was a child, followed her mother and left her hometown, and lived a difficult childhood. Until the past two years, with the great changes in the political scene in the Far East, her mother Yevgenia has become a hot figure in the political and economic affairs of Krasbourg, and she has also changed from a poor girl to a big lady, and the living conditions are very different from before, but the habits and concepts have not changed immediately with the environment, and she is still a girl next door with a bit of grassroots temper and hatred of the rich, and she is still at the stage of "what's the use of this thing" and "why is it so expensive" for art and luxury goods, and there is not enough time to cultivate appreciation ability. Elegant taste requires a long period of edification and accumulation, when it comes to related topics, she, the "rich second-generation upstart girl", of course, can only be beaten by Anthony, who was born in a "rich family".

Roland shook his girlfriend's hand, comforted her not to care about Anthony's sarcasm, and revealed to her with a hint of mystery: "I have a secret recipe that can improve the glass mirror manufacturing process, eliminate the enchantment process in the production process, and greatly reduce the processing cost, are you interested in partnering with me to invest in a new mirror factory?" ”

"I don't need to ask, of course I'm interested!" The giant girl jumped up happily, and only after being happy did she realize a key question: "What do you mean by secret formula?" ”

"The mystery is here." Roland threw up the cinnabar ore in his hand and caught it again, "You know that redstone can refine mercury, but I'm afraid you don't know that after mercury and tin are fused, they can form a special alloy, which can be attached to the glass to have a reflective coating effect, and it is not as easy to fall off as tin foil." ”

The bottleneck of the traditional mirror-making process is that the tin foil is easy to fall off, so it is necessary to add an "enchantment" link to strengthen the combination of tin foil and glass. However, adding to the enchantment link means that you must rely on the power of the caster, and the caster and spell slot themselves are scarce resources, so most of the goods involved in the enchantment process are expensive and difficult to mass-produce, which is the main reason for the high price of glass mirrors.

The biggest advantage of the new process proposed by Roland is that it does not need to be reinforced with tin foil, and the processing process is not complicated.

"A layer of tin foil is plated on the glass, and then mercury is poured on the tin foil mirror, which can slowly dissolve the tin to form a thin layer of tin amalgam attached to the glass surface, so that the mercury mirror is not only not easy to peel off, but also has better reflective properties than any glass mirror made by any existing process." Roland said confidently.

"Are you sure this will work?" Anthony looked at Roland in disbelief, with a hint of excitement in his eyes, "If this process really works, it is no exaggeration to say that it will set off a technological revolution in the mirror industry!" ”

Roland smiled and said calmly: "Whether this new process works or not, I said that you may not believe it, so ask an alchemist to verify it for you." ”

Taking out the "Advanced Communication Stone", Roland contacted Jack in front of everyone and asked him to verify the feasibility of the tin amalgam mirror making process in an alchemy laboratory environment.

"Glass, melted tin and mercury, only these materials are needed?" Jack's confused voice came from the Higher Communication Stone, "I'm familiar with tin amalgam, but can this substance really be used to make mirrors?" ”

"Okay, you can try it yourself." Roland replied confidently.

Before crossing over the earth, he had read some popular science articles on the history of the mirror-making industry, in which he described in detail the processing know-how of "mercury mirrors". It was the emergence and popularization of mercury mirrors that revolutionized the mirror-making industry in Europe in the 17th century, and by the 18th century, glass mirrors had changed from a luxury item that only royal nobles and wealthy families were entitled to to become a cheap mass consumer product.

Today, Vares's mirror-making technology is still at the level of the 17th century on Earth, and the reason why technological innovation has not occurred in time is mainly because Varess is a magical world.

In the "demon-free world" of the earth, the "technology tree" of human society has only one backbone, and technological innovation can only rely on scientific progress, forcing people to move forward along this road with great difficulty, and there is no other way.

Of course, science and technology exist in Vares, but scientific discovery is not the only driving force for technological change, and there is also a way to solve technical problems by magic. As a result, Varess' "Tech Tree" has two trunks, and magic is thicker and more leafy than science.
