I've certainly heard it called 'fish paper' over here. I am not sure if
you can still buy it anywhere, if you can, I am looking for a source...

Well, it probably is eeasier to ignite than fishpaper, but normal paper
is not that easy to set on firs. A soldering iron won't do it, for
example. If a transformer is getting hot enough to ignite paper, you have
My greater worry would be that the paper may absorb moisture and
electrically break down.At one time paper soaked in wax was used, but
this would seem to be an even greater fire risk.

I'd probably not do it in something that was going to be used by somebody
else, or somethign that was going to run unattended. I might do it for
something I was goping to use myself.
