The glass liquid gradually swelled, slowly becoming smooth.
However, it was still far from being a perfectly smooth bead.
Luo De gently placed it in the prepared damp wooden mold, continuously rolling and rotating it, and a "hiss" sound immediately surfaced.
Under the watchful eyes of everyone, the glass sphere gradually approached a perfect spherical shape, its surface flashing with a mix of golden orange and transparent light.
"Oh my!"
One of the slaves couldnât help but exclaim.
The companion beside him reacted quickly, immediately covering his mouth.
Luo De selected clever and astute individuals for the learning process, everyone reacted very quickly, covering their mouths for fear of disrupting Luo De.
Seeing the beadâs shape being about right, after a slight cooling, Luo De handed one end of the iron rod to Labette.
Labette looked tense, "Lord, I, I canât, if such a beautiful thing gets ruined, I canât afford to compensate..."
"Itâs okay, just hold it."
Luo De smiled and forcibly placed it in Labetteâs hand.
Even though itâs uncommon in this world, in Luo Deâs mind, a glass sphere isnât considered a valuable item.
Moreover, itâs an experimental product, if it breaks, it breaks.
After saying this, Luo De used pincers to hold the end of the iron rod, picked up another iron rod and gently tapped at the contact point of the bead and rod.
With a soft "crack" sound, the glass bead fell steadily onto the wooden board.
Everyone breathed a long sigh of relief, wide-eyed, staring intently at the glass ball.
As it gradually cooled, the orange-red glass ball slowly became crystal clear, like a crystal.
Even though it contained some small bubbles, it didnât affect its beauty in this world at all.
"Itâs so beautiful! Is this the legendary crystal?"
Labette bent down, asking softly.
With him speaking up first, other slaves couldnât help but speak too,
"I really didnât expect crystal to be burned out of sand..."
"Magic, it must be magic!"
"Lord, may I touch it?"
...
"You canât touch it."
Luo De warned, "This glazed ball hasnât stabilized, it might explode."
To truly create a glass product, it must be placed in an annealing furnace to cool slowly, otherwise nine times out of ten it will shatter.
"Alright, thatâs enough looking."
Luo Deâs gaze swept over everyone, "Now itâs your turn to make it."
"Labette, you go first."
"Me?"
Labette pointed at himself, looking at Luo De incredulously.
Just as he was about to speak, Luo De interrupted him with a gesture,
"In the future, this kind of thing will be handled by you. Donât fear failure, feel free to try."
Mature techniques are accumulated from experiences of failure, moreover, the materials are not expensive at all.
"Choose two more, and get started."
"Alright, Lord."
Labette turned around, picked one of his clansmen, and then a slave, and the three of them immediately began practicing.
...
...
In the next five days, Luo De stayed in the kiln cave, leading Labette and others in glass making.
Making glass spheres isnât much of a challenge, the key is glass container blowing â this is what changes life conditions.
This also greatly tests the technique, breath control needs to be very precise.
Blowing too strong would cause the glass sphere to explode due to the thin walls;
If the breath isnât enough, the inside wouldnât open properly and would be too heavy, leading to internal collapse.
Luo De himself practiced several times until he successfully blew out a small palm-sized glass bottle.
Then it underwent annealing cooling, after waiting a night this first not-so-attractive glass bottle was harvested.
"Lord, this should be worth quite a few gold coins, right?"
Having seen the glass sphere, Labette was much calmer but couldnât help staring at the glass bottle.
Smooth, sleek, transparent, looking at the sun it can refract into layers of colorful halos.
Fingers tapping lightly on it, it can also produce a series of crisp, pleasant sounds.
If it were in his former tribe, Labette believed it would definitely be a treasure stored in the elderâs box.
"It might fetch some gold coins now."
Luo De nodded slightly, "But itâs just a bottle for holding water."
"Holding water? Youâre saying you want to use this for holding water?"
Labette couldnât believe it, "Such a beautiful bottle for water is a pity..."
In the previous life, there were even people who used it to hold urine.
Luo De couldnât help but murmur in his heart.
Of course, Luo De also understood Labetteâs astonishment, smiled and said: "When you make more in the future, youâll find itâs not magical."
During ancient times, there was glass craftsmanship, but it wasnât recorded in books.
Because wizards looked down on such simple techniques as well.
"You need to hurry and practice, quickly master blowing techniques."
Luo De took the bottle, wrapped it in cloth, and instructed: "Once you become proficient, thereâs new work."
Although Luo De felt glass wasnât valuable, other nobles didnât think so.
Especially some glass crafts and jewelry, Luo De had to seize the time to make some to reap the benefits.
"Yes, Lord."
Labette reluctantly withdrew his gaze, saluted and then picked up an iron tube and ran back to the furnace to continue practicing blowing.
Luo De didnât linger in the kiln cave, carrying the bottle, returned to the manor.
Avril had already learned from Vivian that Luo De was making glaze.
But when she saw it with her own eyes, she still couldnât help feeling a bit excited.
"Is this what you just made, dear?"
Avril held it in front of the lamp, examining it closely,
"Itâs really as beautiful as the glazed cups Man Xiu sent, and even more transparent."
"The glazed cup he sent probably had other metals added, leading to discoloration."
Luo De smiled, "The materials and process are not difficult, when their skills mature they can all make it."
Glass doesnât involve any advanced techniques, but to make attractive products, artisan skills must keep up.
"Then can I have anything I want?"
Avrilâs eyes were glowing with excitement.
"Of course."
"Then I want a complete set of glazed cups, also glazed bottles for magic potions, and the lamp shades to be glazed."
Avril pondered seriously.
"No problem, think slowly."
Luo De took out several glass balls and gave them to Avril.
These were the products of experiments, in order to let the slaves learn the complete process, they all underwent annealing and are considered finished goods.
Because Vivian liked them, Luo De thought Avril would too, and brought them back.
Girls are girls, thereâs never resistance to shiny things.
Avril was the same.
While Avril was playing with them, Luo De changed the topic and asked, "Are the healing potions ready? Vivian and I should set off."
"Theyâre ready, but we could only make the most basic healing potions with our materials."
Avril sighed slightly, "Fatherâs body may be severely injured due to Cultivation Breathing Technique, I wonder if ordinary healing potions will be effective..."
"Just prepare them first, if thereâs an issue weâll deal with it specifically then."
Luo De comforted, "If it really doesnât work, perhaps we can seek help from the Dawn Society."
"Mhm."
Avril nodded vigorously, "Then should I go prepare for you?"
Luo De saw Avrilâs eagerness and patted her waist, "Yes, hurry along."
Avril nodded and immediately turned to busy herself.
Watching Avrilâs back, Luo De couldnât help but sigh silently.
Luo De wanted to take Avril to the Red Griffin Clan, but was worried about Avrilâs safety.
Moreover, Black Pine Ridge needs someone to stay and guard it, either Avril or Vivian has to stay, allowing Luo De to have real-time information about the territoryâs situation.
Comparatively, Vivian is more suited to go with Luo De to the Red Griffin Clan.
Even if there are occasions where Avril needs to make appearances, Vivianâs portrayal will suffice.
However, this is the most rational choice.
Emotionally, Avril also wants to see her father.
"Baron, sister seems a bit downhearted...quite complicated emotions." Vivian beside suddenly spoke.
"I know."
Luo De nodded,
"Before leaving, Iâll properly reassure her."
