At the Count's birthday party, Liszt's surprise was the resumption of a calm relationship between him and Ronassa Golden Ears of Wheat.

Perhaps this is the instinct of the aristocracy, and after the passion, they return to their respective life trajectories.

Non-interference.

Except for some emotion, he didn't have many other ideas, and returned to Flower Town after a short break in the afternoon. The affairs of the territory are complicated, and the existence of him as the backbone is always unsettling. However, when he returned to the territory, he found that there was nothing to deal with urgently.

So he went straight to the burial place on Dark Horse Island to extract the magic power of the fire dragon.

Infusing the dragon bones with magic power, and also asking his knights to help, extract the fire dragon magic power alone and pour it into the fire dragon jar, which can only be done by himself, after all, he is the only one who has the "Magic Eye" fighting spirit secret technique. Once you become proficient, the speed of canned fire dragon magic increases.

It can extract about four tons of volcanic glass in a day, and fill nearly eight cans of dragon jars.

After extracting the dragon's magic, the volcanic glass was immediately sent to the newly built crystal workshop in Port Town, where it was handed over to the crystal craftsman Brad to carve the vessel.

Volcanic glass is not as hard as crystal, but it is much harder than glass, and it has good permeability, which is suitable for making glassware. Drinking glasses, wine glasses, teacups, teapots, wine bottles, glasses, test tubes, and small bottles for potions—all of these utensils are not for sale.

The reason is simple, the volcanic glass has a blocking effect on the magic of the fire dragon, so he guesses that this material can also isolate the magic of other dragons.

Then its value is incalculable.

In his spare time, Liszt also went to the blacksmith's shop to find a blacksmith's stove, a blower skin, and charcoal, and experimented with high temperatures—he remembered that glass could be melted and blown repeatedly.

Therefore, I wanted to melt the residue produced when Brad carved volcanic glass and knead it into other shapes for secondary use.

The charcoal burned in the blacksmith's furnace, and the servants kept stepping on the blast skins, blowing the charcoal in the furnace to the fire. The volcanic glass was placed in a furnace in a tin pot and burned - he was not sure what the melting point of the glass was, or what the softening point was, and if it was higher than the melting point of iron, the experiment would have failed.

Thankfully, when the tin can just turned red, the volcanic glass began to melt.

It quickly melts into a bright mass of soft substance.

Liszt ordered the operating servants to pour out the volcanic glass and place it on another piece of red-hot iron. Then he had one of the servants stick an iron pipe into the soft glass and blow hard. The knight's lung capacity is very large, and with a light blow, the soft glass begins to expand.

When it swelled into a spherical shape, Liszt told him to stop and pulled out the iron pipe.

After a little treatment of the bottle mouth, an ugly glass bottle is freshly baked. Later, the master master of the Huolong Brick Factory came to help complete the annealing process - annealing was discovered by the workers of the Huolong Brick Factory, and after the bricks were burned, in order to cool down faster, the water splashing method was used.

However, the bricks splashed by water are easy to break.

Therefore, under the incentive of the lord, the workers found a reasonable annealing process after a long time of exploration, which greatly reduced the crushing strength of the fired product. There were ten workers, so they were rewarded with ten silver coins each, and became the first masters of the Fire Dragon Brick Factory.

From the original simple worker, upgraded to a qualified craftsman.

Because volcanic glass is a new product, the master does not know what temperature is the appropriate annealing temperature, so he can only slowly explore. However, after the volcanic glass cooled, he took the initiative to report to Liszt: "My lord, there is one thing I don't know if you want to know. ”

"You say. "Liszt always encouraged his people to discover new things.

Master Fu is not very old, about twenty years old, named Artest, a serf from the Eagle Kingdom: "You know that the dragon brick factory is often looking for new materials for calcination, and once the serfs of the thorn caravan brought a yellow-white rock, which can still feel a little transparent in the light. ”

See Liszt listening carefully.

"I threw these rocks into the kiln and calcined them, but they were very strange and quickly melted into a puddle, and when I took them out, they quickly changed again...... Like, like this volcanic glass that you asked me to anneal, but it's muddy. ”

"Huh?"

Liszt raised his eyebrows: "Like volcanic glass?"

"Yes, it's also soft, solidifies quickly, and it's somewhat transparent. I gave it to the master craftsmen of the brickyard to watch, and they couldn't figure out what it was for, and it quickly crumbled, and we decided that it was not suitable for calcination, so we gave up the rock. Artest said.

His words touched Liszt greatly.

If I guessed correctly, Artest calcined into the same glass he had been waiting for, the original glass made of quartz.

The stone brought by the serfs of the thorn caravan must have been the raw material of glass - quartz.

Liszt had searched for quartz, and he had tried to put all the stones and dirt in the territory into the kiln of the dragon brick factory, but the glass had not been calcined.

There was an impression in the haze that it seemed that the sand by the sea could make glass, but the result was disappointing, and the sand on the seashore could not be calcined into glass.

The sand on the beach here seems to be the remains of sand grains formed by the weathering of ancient coral reefs.

Unexpectedly, the rocks brought from other places might be quartz ore, and Liszt immediately issued an order to let Galtai take charge of this matter: "Consultant Galtai, what you need to do is to buy a batch of this type of rock that Artest said, and then cooperate with the forged glass experiment, remember to keep it secret." ”

"My lord, can this stone really be calcined into glass, like the cups you make out of volcanic glass?" Galtai wondered.

"Yes or no, we have to wait until we have experimented before we make a decision. ”

......

The possible discovery of quartz overjoyed Liszt, and he could already think about how glass would accumulate wealth as a specialty of Black Horse Island in the future.

In an era when crystal was expensive, the petty aristocracy certainly could not resist the temptation of glassware.

Of course.

Liszt didn't get carried away until he was sure that the rock was quartzite, and he continued his experiments with volcanic glass—to make sure that the re-calcined volcanic glass still had the effect of blocking the dragon's magic.

The dragon needle absorbs a little dragon magic.

Injected into the new "Fire Dragon Bottle", he soon found that the fire dragon magic was still in the form of magic power, flowing quietly in the fire dragon bottle, without the slightest leakage. This proves that the effect of the volcanic glass in blocking the dragon's magic does not change as it melts and transforms.

"Therefore, the volcanic glass of Black Horse Island does have high strategic value, and it is likely to help me subdue the dragon and complete the great cause of dragon riding. ”

He thought of it with a smile.
