Although Hu Ke'er had never made glassware with her own hands, she was no stranger to the process. After all, she used to be a researcher who had studied bulletproof glass fibers. She could easily recite the steps for making glass from memory. However, when it came to actual operation, she would have to rely on the young blacksmith.
With this in mind, Hu Ke'er quickly found the young blacksmith and began to talk to him.
"Blacksmith, can you make the extra - large glassware like the one in my drawing?"
"Glass?"
Hearing Hu Ke'er's words, the blacksmith looked confused.
"Well, it's actually quite simple. You just need to heat the sand evenly at an extremely high temperature and then rotate it during the refining process," Hu Ke'er said softly.
"I can give it a try, but I can't guarantee success," the blacksmith said with a simple - minded smile.
"It's okay. If we fail once, we'll try a second time. If we fail twice, we'll try a third time. In any case, we must make this thing!" Hu Ke'er patted the blacksmith on the shoulder.
"Okay, I'll do my best!"
Hearing Hu Ke'er's words, the blacksmith nodded vigorously and then started making the glass.
Of course, during the glass - firing process, controlling the heat was crucial. Since this was the blacksmith's first attempt at making glass, he failed as expected. Then came the second attempt, the third...
Fortunately, the blacksmith had previous experience in iron - smelting. Finally, after dozens of failures, he managed to produce bright glass beads.
"Sister Ke'er, is this the glass you want?"
"Yes, this is it!"
Seeing the impurity - free glass beads made by the blacksmith, Hu Ke'er nodded vigorously.
"However, just making these glass beads is not enough. We need to make a container that can hold things. Well, why don't you try to make a cylindrical jar that is open at one end and closed at the other for me first!"
"Okay, I'll try again!"
After hearing Hu Ke'er's words, the blacksmith started refining again. This time, having mastered the heat well, he succeeded on the first try.
"This should be the right one, right?"
The blacksmith handed the glass cup he had made to Hu Ke'er.
"Yes, this is it!"
Seeing that the blacksmith had made the glass cup so quickly, Hu Ke'er was overjoyed.
"Great! This method works. Next, we just need to make a large - sized jar," Hu Ke'er said softly.
"Um... I might not be able to make the large - sized one," the blacksmith showed a hesitant look.
"Huh? Why?"
Hearing the blacksmith's words, Hu Ke'er asked in confusion.
"Because I don't know how to shape the glass into that..."
Oh right! How could she forget this!
In her original world, Hu Ke'er had never seen flasks that were several meters tall. On the one hand, they were inconvenient to transport, and on the other hand, shaping them was extremely troublesome.
"No way! We've come this far, and we've already made the cup. Are we really going to start all over again?"
Hu Ke'er frowned and murmured to herself with a sad expression.
"Little junior sister, what's wrong with you?"
Just then, Chen Tianyi suddenly appeared in front of Hu Ke'er and asked. Hu Ke'er didn't hide anything and told Chen Tianyi about the current situation. Chen Tianyi frowned slightly, thought for a while, and then raised a question.
"Um, little junior sister, can spiritual energy be used for glass - blowing?"
"Spiritual energy?!"
Hearing Chen Tianyi's words, Hu Ke'er was stunned for a moment. Then she frowned and thought for a while.
"I'm afraid this won't work."
"Huh? Why?" Chen Tianyi asked.
"Senior brother, have you forgotten the spiritual - energy flamethrower I made before? Spiritual energy is likely to explode at such a high temperature. By then, the glass will probably be blown to pieces."
"I see..."
Hearing Hu Ke'er's words, Chen Tianyi fell into deep thought.
"Then the wind driven by spiritual energy should work, right?" Chen Tianyi thought for a moment and said.
"This could work!"
Hu Ke'er immediately became excited.
"Senior brother, can you control the wind created by spiritual energy well? If you can, let's give it a try!"
"Let's just give it a try first!"
Seeing Hu Ke'er's excited look, Chen Tianyi smiled slightly.
"Okay, then I'll have to trouble senior brother and the blacksmith to cooperate. Blacksmith, you control the heat well. When it's time to blow the glass, senior brother, you try to control the wind."
"Okay!"
Hearing Hu Ke'er's words, the blacksmith and Chen Tianyi looked at each other and then nodded slightly. Without hesitation, the two began to cooperate to make the extra - large glass flask.
"Bang!"
"Bang!"
"Bang!"
"..."
After countless failures, Chen Tianyi and the blacksmith finally made a glass flask that seemed qualified to Hu Ke'er.
After the most difficult part, the glass flask, was completed, it was time to make the conduits, condensers, and other things with similar principles. With the experience of making the glass flask, Chen Tianyi and the blacksmith worked together smoothly and quickly made a complete set of condensation and distillation equipment.
"Amazing! My spirit - stone refining furnace is finally made!"
Hu Ke'er watched as the two made each part of the equipment and then directed them to assemble these parts. Finally, after more than half an hour, Chen Tianyi assembled these parts. Then they began to put the primordial stones into it for a test.
"Okay, senior brother, pour water into the condenser tube, and then we can start trying to refine high - purity spirit stones!"
"Okay!"
Hearing Hu Ke'er's words, Senior Brother Chen nodded expectantly. Finally, after pouring water into the condenser tube as Hu Ke'er said, he put the spirit stones into the huge flask.
"Okay, senior brother, next, try using the spiritual fire and control the temperature at around 700 degrees Celsius."
"Seven hundred degrees Celsius?"
Hearing the number Hu Ke'er mentioned, Senior Brother Chen, who had been eager to try, was stunned for a moment.
"It's the temperature for refining spirit stones. It's the same temperature as you used to refine spirit stones before!"
"I'm not good at controlling the temperature..." Chen Tianyi said with an embarrassed smile.
"Oh, what should we do then?"
"I can do it! Let me try!"
Just when Hu Ke'er's plan was about to be derailed again, the blacksmith volunteered.
"Okay, let's give it a try!"
Hearing the blacksmith's words, Hu Ke'er nodded. Then the blacksmith lit the fuel under the flask and started refining the spirit stones!
"Junior sister, can you really refine high - purity spirit stones like this?"
Seeing the primordial stones in the flask slowly decompose and the light - red spiritual energy slowly rising in the flask, Chen Tianyi asked in doubt.
"Senior Brother Chen, just watch. If there are no accidents, we'll get high - purity spirit stones soon!"
