บท 57: Detailed Operation, Purifying Sulfur

Some supplies had already been piled up in the utility storage warehouse, but after Su Mo poured out all the sulfur ores, the warehouse finally looked somewhat full.

A faint stench effused from the surface of the ore.

After examining the powdery yellow substance on the ore, Su Mo lowered his head and picked out a smaller piece, bringing it to the workbench.

The process to purify sulfur ore was extremely simple.

One only needed to heat a sulfur monomer mineral of an acceptable purity in a distillation flask. When the temperature reaches 200 degrees, a filter is used to remove any unmelted impurities to ensure purity.

The remaining substance then resumes heating after filtering. During this heating process, the remaining substance is stirred to continue evaporating and filtering the impurities.
