The warehouse for miscellaneous goods was already nearly half-filled with supplies.
After Su Mo had moved out all the sulfur ore, the Miscellaneous Goods Warehouse finally looked well-stocked.
A faint stench wafted from the surface of the ore.
Su Mo rubbed the powdery yellow substance on the ore, then lowered his head, picked out a smaller piece, and brought it to the workbench.
Purifying sulfur ore was an extremely simple process.
All he needed to do was place the sulfur mineral, whose purity looked fairly decent, into a Distillation Flask and heat it. When the temperature reached around 200°C, he would use a filter to remove the impurities that had not yet melted, ensuring its purity.
After filtering it, he would continue heating the remaining material, stirring it along the way so the remaining impurities would continue evaporating and be filtered out.
Once the temperature reached 400°C, sulfur gas would begin to evaporate. Collecting the evaporated sulfur gas and cooling it until it solidified would yield relatively pure sulfur.
In ancient times, the reason gunpowder had not been developed sooner was that extracting pure sulfur was relatively difficult.
However, with the current workbench, extraction was no problem at all.
Su Mo returned to the Energy Room, connected the generator to the power supply, went to the workbench, and activated the self-check button.
The indicator lights flashed red, green, red, and green. Once the self-check was complete and they turned green, Su Mo put on the Mechanical Arm and began the purification process.
The workbench was already equipped with a complete set of purification tools.
He used the Mechanical Arm to crush the sulfur ore into powder, brought over the purification vessel, and poured it in until it was two-thirds full. Then he began operating as required.
