Now that the children have plugged their ears, stomped their feet and left
the room, the curious might look at a fairly comprehensive article at
http://www.woodzone.com/articles/wood_finishes.htm
or http://www.taunton.com/finewoodworking/pages/w00060.asp

Of course, they've got it all wrong with their definition of "Varnish," and
all lacquers are created equal....

Yikes, you are bizarre. Neither of those articles say anything about
lacquer and shellac forming esters as they cure (quel surprise, eh?),
nor do any such articles exist, because it was a false statement. I
could be wrong though, maybe you aren't nuts. Maybe you're just a 12
year old here talking out of his ass. I doubt you have ever cut a piece
of wood in your life.
