As for why the gas won't flow back?
That's because there is a check valve on the part where the hand presses, which closes when pressed down and opens when pulled up, sucking in the surrounding air into the bellows.
Soon, under Boris's guidance, Rein inserted one end of the iron pipe into the clay furnace and fitted the other end onto the bellows.
"Hmm, not bad!" Lagaray glanced over, nodded her head, and signaled that Rein had done a decent job.
"It's about time, continue to add some charcoal and burn it for a bit, let the clay solidify, then we can put in the Glowstone," Lagaray said, patting the clay in her hand and standing up.
"Is that it?" Boris couldn't help but exclaim in surprise.
He hadn't expected Lagaray to use the "reduction method" for melting Glowstone, which completely baffled Boris, who was observing attentively.
This method was used to melt the most common ores such as brown iron ore and red iron ore.
It was the most primitive and simplest of methods.
