UrbanDictionary should be right up your alley.  You seem to live as
far from access to street jargon as I do, or nearly so.

But not what the books call "plasma spray" or similar.  IIRC, you can
spray glass through an arc and deposit it on metal as enamel, as well
spray as other mixed metal-on-metal coatings.  I never saw the rig,
just read about it.  It sounded real cool until I realized that the
gear was big bucks.

But I'll have to measure the rate of wire feed for my humble machine,
see if the docs mention the actual voltage and a way to reverse the
polarity.  New stuff to learn.  


Unrelated topic: If anybody's doing tinning of copper cookware, tell
me how you do it.  I've done it a dozen or more times.  Sometimes I
get perfect results, other times less than perfect.  So I'd be keen to
learn any tricks that I don't know.  I've been using Canada Metal
Tin-Rite(tm), sometimes with extra tin filings, big propane torch,
either cotton, leather or 0000 steel wool for wiping.
