This was because it was more convenient when they went out for experiments or gathering materials.

"Well, it's a beautiful building.
Emperor Taue (Hilde) said in an impressed voice. Indeed, the building is still new.
Jin guessed that it seemed to have been built with engineering magic.

It is about twice the size of an elementary school classroom. It seems to be sufficient for small-scale production.
"This way please."
Marikka led Jin, Emperor Taue (Hilde), Flora, Zion, Reiko, and the five colored golem maids into the workshop.

"Oh, it's so neat!"
At first glance, Jin noticed that the workshop was modeled after the one on Horai Island.
The shelves of materials were lined with various metals and magical materials, and the ordinary tools were well maintained.

They were surprised to see the five-colored golem maids behind them.
"What is that?
Golem maidens!

"Oh, that's so elaborate!"
The three of them may have thought they were whispering in secret, but Jin and the others could hear everything they were saying.
Marikka clears her throat.

"You are indeed a teacher.

Reiko is just as popular as Jin.

Marikka came to her senses and gave them a hard time.
"Yes, yes."

After calming down a bit, the three girls returned to their respective seats with a pat on the back from Marikka.

"Recently, I've been working on cubic zirconia," Marikka explains, pointing to the prototypes lying on the workbench.

Emperor Taisho was impressed and said, "They are different from crystals,
"Is it different from crystal?"
Flora questioned.

"Yes. It is a mineral a little harder than crystal, and is a specialty of the Nordic Federation.
Marikka replies.

"Heh. ......"
Flora picks up one of the cut glasses and looks at it.
"The clarity is wonderful. And they seem to sparkle more than quartz.

The sparkling appearance of cut gemstones is due to optical phenomena such as internal refraction and reflection.
When the refractive index is high, incident light is <

The light reflected from the surface also enters the eye at the same time, so the normal light and the rainbow-colored light are mixed together, giving the gem its unique brilliance.
The refractive index of cubic zirconia is 2.13, while that of quartz is about 1.543. The higher the refractive index, the more sparkling it appears.

By the way, the refractive index of diamond is 2.42, which is one of the highest among minerals.
Rutile (titanium dioxide) has a refractive index of 2.62 to 2.90, which is higher than that of diamond, However, it is not distributed as a gemstone because transparent crystals are almost impossible to obtain in the wild.

"If we treat it as a gemstone, wouldn't it have more added value?"
The Grand Emperor Hilde said,
"Master Hilde, however, we have already started selling them as cut glass and accessories, so I think it would be difficult to raise the price suddenly.

"Oh, I see. That's too bad."
At this point, Jin comes up with an idea.
"As I recall, cubic zirconia can change its color by adding elements. I don't know what color can be changed by adding what elements, so I'll have to check it out by trial and error.

"Then it would add value. Cubic zirconia in many colors is kind of nice."
Theon said, entranced. Jin thinks to himself, "She is a girl after all," which is a bit rude.
"Oh, that's a nice idea.

Marikka agreed.
"Okay, I'll check this out too.
"I'll look into that, too," said Jin.
