The metal sphere was a full four meters wide, with a radius of two and a half meters, and the temperature inside was extremely high, necessitating continuous cooling with clay, fine sand, and cold water.
Meanwhile, over a dozen thick pipelines were continuously supplying it with energy.
This scene far exceeded Lin Feng's understanding.
He couldn't comprehend why such a hazardous and irrational object existed inside the battleship.
Dozens of workers nearby continuously cooled it with sand and fresh water; ordinary sand particles were heated to a high temperature of two thousand degrees within just a few minutes.
The primary component of sand particles is silicon dioxide, also known as quartz sand.
When quartz sand is heated to one thousand seven hundred degrees, it melts into a liquid, glass-like substance and then cools to form softened glass.
This is also the main shaping stage in the glass industry.
