Chapter 928 - Refining Gold (1/2)

Lin Mu carefully watched the molten gold and scanned it with his spirit sense. He could feel that other than gold, there were other substances mixed in it. They were not like chunks or separate particles though and seemed to be mixed finely with the liquid gold.

”From here, I can increase the heat and let it separate out.” Lin Mu muttered and increased the output of flames.

~SHUA~

Like a forge that had just been stoked with bellows, the flames directly doubled in intensity. The iron cauldron was pretty much hidden by the flames, and it looked like there was a fireball floating in the air.

The area around Lin Mu had already been dried up by now and the ground directly below the Cauldron was scorched black. The liquid gold bubbled even more and the heat continued to pour into it.

Some time passed and Lin Mu could see floating particles on top of the surface of gold.

”There we go!” Lin Mu exclaimed.

It was his first time doing it, and he had managed to remove a majority of the impurities.

'Now to scoop them out.' Lin Mu began with the next step.

He took out another tool from his ring, which was like a shallow ladle. He steeped it in the liquid gold and skimmed its surface, removing all the impurities that were floating on it.

The impurities were a mixture of colors, with the majority being black, Grey and white. Throwing the impurities to the side, Lin Mu continued heating the gold. There were still some bubbles coming from the gold and he needed to continue doing it till the gold stopped bubbling.

Lin Mu checked it with his spirit sense and saw that it was now far purer than before.

”Now for the final step… actually refining it enough to make it reduce in volume.” Lin Mu muttered in a serious tone.

This step was also the most difficult part of the entire process, since it needed pressure and heat at the same time.

~clang~

Lin Mu put the lid of the cauldron on and rotated it so that it would lock in place.

This time he used both his hands and used gestures to control the heat while keeping an eye on the liquid gold inside with his spirit sense. Since most of the gases in the form of impurities were already removed, the internal pressure did not spike like it would have normally.

The volume of gold stayed the same for the time being, but its temperature kept on increasing.

”Focus… focus…” Lin Mu muttered as he increased the heat even more.

The cauldron itself started to turn red as the heat started to overcome the formations that protected it. Still, it wouldn't break just from this and it was just the temperature maintaining formation that had failed.

The durability and formation was still working and won't break… at least not now.

By the time the heat reached a new level, the liquid gold inside had change color once again. Now, it was an almost blinding white in color. The heat had reached a peak point and Lin Mu knew it was time to circulate it.
