I suspect the peacock colors in leaded glass is from an HCL wash.
Thanks Ed.

I wondered about those colors when I read about the iridescence that
comes
from HCL etching, but I didn't see anything on Google about it being used
as
a coloring method. Probably I wasn't asking Google the right questions.

that usually comes from vapor deposits of stannous chloride applied to
the slightly under molten temp glass at a certain point in the
production of sheet glass.
there are other chemicals used in this too, but all applied to hot
glass as a vapor, for example dichroic glass is 10-30 layers of vapor
deposition of different kinds of metals in a vacuum chamber.
none of these processes is any type of etching with acids.
