Hogwarts Collector, I cast a spell with the Eye of God

Snape gave the order, and the whole classroom immediately became busy.

Students rushed to the storage cabinet to get the ingredients, and then started to cook soup in pairs.

Ye Ting and Susan were in the same group.

Susan was very talented in Transfiguration, but she seemed a little flustered in the potion class.

After a burst of smoke and fire, she accidentally turned into a clown face, and her efforts only exchanged for a crucible of green waste.

“This potion is much more difficult than Transfiguration.”Susan stared at the green liquid in the crucible with a bitter face, her eyebrows twisted into a”chuan” shape.

As for Ye Ting?

He had already started to study potions in depth during the holidays. With Lisa’s talent in this area, a mere scabies potion would not be difficult for him.

However, it seemed that because he had lost face by failing to test Ye Ting just now, Snape targeted him again.

“Mr. Ye, why did you use this substandard crucible? Are you trying to attract attention?”

When Ye Ting’s potion was halfway through, Snape came up and mocked him as if he had caught something.���

Ye Ting’s equipment was indeed different: a black crucible of unknown material, beakers and flasks not made of crystal but engraved with precise scales, and a scale with scales written on it…

These equipment were very different from the retro equipment of other young wizards present.

Facing Snape’s provocation, Ye Ting stood up and met those cold eyes without fear.

“Professor Snape, I think we need to discuss the purpose of my experimental instruments.

The other party was obviously looking for trouble, but Ye Ting did not intend to indulge him.

With Lisa’s talent as a backing, he had enough confidence to deal with Snape’s challenge.

“All my experimental equipment is different from others because they are all Muggle products.”

He picked up a beaker and said seriously,”I personally think that Muggle products have gone further than us in this kind of standardized device that does not require alchemical enchantment.”

He gently shook the beaker in his hand and continued,”As you said, potions is a discipline that requires precision and rigor, and in this regard, Muggles do much better than wizards. Each one is marked with precise scales, which is much better than our crystal bottles of different sizes and no measurement. Each Muggle test tube and beaker is made exactly the same, accurate to milliliters, which can greatly improve the accuracy of preparing potions.”

As he spoke, he pointed to the scale next to him.

“Look at this again. We wizards are still using those old-fashioned brass balances, which are good enough if they can reach an accuracy of 1 gram. But what about the pan balance used by Muggles in experiments? The accuracy can reach 0.1 gram! Just for weighing medicinal materials, I am already ten times more accurate than others. If I switch to a more advanced mechanical analytical balance, the accuracy can reach 1 milligram, which is a direct improvement of 100 times!”

“Finally, let’s talk about the crucible issue that you are most concerned about.”

Ye Ting paused for a moment, giving Snape some time to digest his previous words, and then continued.

“Freshmen are required to use pewter crucibles.

To be honest, this kind of crucible has a low melting point and is not corrosion-resistant.

It is cheap and has no advantages.

Even Muggles have eliminated this kind of thing.

The problem of low melting point can be solved by lowering the temperature and sacrificing the boiling speed, but poor corrosion resistance is a big problem.

This is why you have always emphasized that the last medicinal material, porcupine quills, must be added after the crucible is off the fire!

”

“Because the porcupine quills and the medicine being boiled are both acidic, once dissolved, they will mix into a highly corrosive mixed acid. This mixed acid reacts actively at high temperatures and can easily melt through the bottom of the pewter crucible!”

Crash!

” As soon as he finished speaking, a deafening noise suddenly rang out, and the whole classroom was shaking.

Ye Ting reacted quickly, grabbed Susan’s arm, pulled her behind him, and hid beside the crucible.

The girl only felt her wrist being tightly grasped, and then her chest sank, the two water balls were pressed into round cakes, and the whole person was pressed to the ground by Ye Ting.

She was originally panicked, but at this moment she felt an inexplicable sense of security in her heart.

After a while, the two stood up.

It turned out that the crucible of Justin and Ernie next door had exploded violently, and the potion in the pot splashed everywhere, and large charred holes were instantly burned on the ground and walls. The classroom was filled with a pungent smell, which was disgusting.

Justin’s left half of the body was splashed with magic potion, and half of his face quickly broke out with dense scabies, which looked painful.

Ernie suffered on the right half, and the two of them, one on the left and one on the right, were also a perfect match.

“It seems that there are already unlucky people who failed because of convenience.”Ye Ting looked at this scene with gloating.

“”A bunch of idiots!” Snape came over with a gloomy face, waved his wand, and the potion spilled on the ground was cleaned up instantly.

At this moment, Snape was almost furious. He watched the precious potion flow into his storage cabinet, and his beloved treasure collection was emitting white smoke.

Snape was so distressed that he almost bled. These precious medicinal materials were his favorites!

“Professor Snape, although the accident just now was caused by Finch-Fletchley and MacMillan’s mishandling, the real reason is actually the material limitation of the pewter crucible itself.”Ye Ting took the opportunity to interrupt.

While speaking, he opened the lid of his crucible and threw all the porcupine quills that had been processed long ago into it!

“But my graphite crucible is different.” Ye Ting smiled proudly,”This crucible is a masterpiece of modern Muggle materials science, made from natural flake graphite. The price is about the same as that of a pewter crucible, but its performance is far superior.���Pewter Crucible!”

“This graphite crucible is not only extremely corrosion-resistant and can withstand temperatures of over three thousand degrees, but its thermal conductivity is also far superior to that of a metal pewter crucible! Using it to brew potions, you can completely skip the step of removing the fire from the potion, and there is no need to worry about any danger.”

In fact, Ye Ting didn’t say one more thing, that is, the graphite crucible also has special conductivity.

This crucible does not require traditional flame heating, but can be heated by electromagnetic induction like an induction cooker.

Compared with traditional flame heating, electromagnetic induction heating is not only more uniform, but also faster. Most importantly, this is more convenient for Ye Ting.

He only needs to use [Fingertip Thunderstorm] to easily complete the heating process of the crucible.

It can be said that the graphite crucible is perfectly suitable for the Rose Witch and can be regarded as Lisa’s selected premium product.

Snape looked down at the black crucible in front of him, and he found that everything was just as Ye Ting said, the light green liquid in the stone The ink in the crucible was boiling fiercely, but the inner wall of the crucible was still as good as new, without any change!

Moreover, since the heating was never interrupted during the brewing process, the temperature of this potion was almost just right.

At this moment, in Ye Ting’s crucible, the light blue potion was taking shape at an astonishing speed. The entire brewing process took less than a quarter of the time that other little wizards theoretically took.

When the materials in the crucible were finally boiled into an amber transparent liquid, Snape finally nodded slightly.

He knew that Ye Ting’s potion had been successfully brewed, and its degree of completion even surpassed many professional potion masters.

This showed that his new experimental equipment was feasible.
