You may be remembering something you actually read about copper and *gas,*
but it may have referred to *natural gas* used to heat houses, etc. Natural
gas causes copper to corrode to a black, flaky substance that clogs jets,
etc. I have seen this, 'cause did it before I knew.

Yet copper is now not only approved, but is the line of choice for
connecting natural gas appliances.
