You’re left with 99% pure silicon and carbon monoxide (that’s from the carbon we added, bonded to the oxygen we removed from the silicon dioxide). Chemistry break!

The Fuss about Methane

Legal Planet

It replaced an earlier, more dangerous, product called “town gas” or “coal gas,” which consisted mainly of hydrogen and carbon monoxide and was produced by heating coal in. “Natural gas” was a marketing term for this then-new, safer gas pumped through urban distribution pipes starting in the 1940s. the absence of air.
