The Count Saigul beside him also received a mask, but just from the appearance alone, it was not as sturdy as the one Regent had.
Lavoisier led Joseph towards the gate of the chemical factory at the front, curiously asking: "Your Highness, what is this gas mask you're talking about?"
"Simply put, it's a tool that can isolate harmful and toxic gases," Joseph gestured with his hands around his head, "made of leather and copper buckles covering the head, with glass observation ports at the eyes, and a tube at the mouth and nose part. Inside the tube are filtering materials like cotton, carbon granules, and lime.
"This thing can isolate most harmful gases; for example, it's best to wear it near the heating furnace."
Upon entering the workshop, the smell of sulfur became stronger, and Joseph found himself uncomfortable, even through the mask.
Saigul added beside him: "Sounds somewhat similar to the bird-beak mask used by doctors."
