Quite right about the sulphides. I have a gas-heated and
gas-cooking home - with the old-fashioned pilot lights on both.
Cannot have any ornamental silver candlesticks or such standing out
in the dining room for more than a day or so before it starts to turn
black. On the other hand, my wonderful collection of old copper
pots can hang in the kitchen for many months before even dulling.
One other tip for those with natural gas homes - don’t even think of
trying to grow ferns indoors. You’d think we would shrivel up and die
too, but long-in-the-tooth, we’re fine. Pat
