Chapter 155 The Composition of Mutton Fat Jade

"Why do you say that, girl?"

The host's voice carried a hint of anger.

Lu You's long eyelashes drooped slightly. "There are five ways to determine whether this is genuine mutton fat jade."

A clapping sound rang out.

"Then, beautiful lady, may I tell you what the five types are?"

Xing Shu stood in the crowd, a wicked smile curving her lips. She held a folding fan in her right hand and two strings of candied hawthorns in her left.

Lu You: ...

"First, visually, the color is white—mutton fat white is not pure white, but a white with an oily sheen."

Some of them may have a slight yellow tint when white, while those of poor quality may have a slight light gray tint when white.

When placed alongside other pieces of white jade of varying quality, this piece appears exceptionally white, lustrous, and translucent.

Lu You wore a red dress, her hair as black as ink, flowing and graceful.

Her slightly upturned face was exquisite and translucent, and her calm and gentle black eyes exuded a serene indifference, yet were as unfathomable as the deep sea.

"But it's pitch black now, so we can't see the color of the jade at all."

One of the people below the platform asked, puzzled.

Lu You: ...

"Secondly, the touch should be oily – meaning the jade should be as smooth and delicate as mutton fat, without any white spots or impurities."

It is semi-transparent, and the surface is as if it is covered with a thick layer of oil, giving the impression that it will melt upon contact with fire.

When mutton fat jade is constantly touched in people's palms, it naturally develops an "oily" feel on the surface of the jade. This phenomenon can also be found in some fine white Hetian jade.

When mutton fat jade is submerged in water and then lifted, no water droplets will stick to it. Therefore, mutton fat jade with a high oil content also has excellent "cotton-like" texture, which refers to its toughness.

Lu You picked up the jade hairpin from the box with her well-defined fingers, and gently rubbed the jade with her thumb.

A few playful strands climbed up her exquisitely beautiful features, adding a touch of allure to her icy demeanor. Beneath her slender, willow-leaf eyebrows, her dark eyes were like the summer night sky, and she possessed an ethereal and aloof air.

"toughness?"

Lu You parted her red lips slightly and replied calmly, "That's right."

"But for us, doesn't it all feel the same to us?!"

How could a layman understand these things?
It's just a piece of jade, isn't it?!

Lu You: ...

"Third, sufficient water content - water content and spiritual ground are terms for the transparency of jade. In tremolite jade, a thickness of 2mm is often used as the standard."

According to this standard, white jade is translucent to opaque, while mutton fat jade, with its excellent translucency, is translucent.

Lu You's long eyelashes fluttered, the alluring charm at the corners of her eyes concealed by her cool and aloof face.

She gently pursed her pink lips and raised the jade hairpin in her hand by the light of the lantern, trying to make sure everyone present could see it.

"Fourth, fine structure - the tremolite in mutton fat jade is in the form of microfibrous metamorphic crystals and aggregates. The grain size of the tremolite crystals can be measured under electron microscope and optical microscope."

The tremolite fibrous structure in mutton fat jade has a length (longitudinal) of 0.033-0.01 mm and a width (transverse) of 0.0006-0.001 mm.

These microscopic fibrous, villous, and felt-like tremolite crystals intertwine to form villous, felt-like, and interwoven structures.

Microfibrous, villous, and felt-like tremolite crystals, when viewed under crossed polarized light, do not exhibit uniform extinction within the same angle.

"fifth……"

"Wait, what are electron microscopes and optical microscopes?"

Also, what are those microfibrous, villous, felt-like tremolite crystals?

The middle-aged man, dressed in coarse linen clothes, posed a question about death.

Waaah, please comment, please vote, please add to favorites, I'm so heartbroken (-ω`)
