I have a candle on my windowsil. Do you know, I looked at it this
afternoon, and it had *melted* in the sun. It's now actually welded to
the sil; I can't move it at all.
Do you have any idea what the hell temperature parafin wax melts at?

Paraffin is a by-product of oil refinement.
Essentially it's just solids from mineral oil.
Typically, paraffin used to seal canning jars melts
at a little lower temperature than "candle wax".
Those cheap tea-light candles are mostly paraffin
too, I think. A good bees-wax candle will melt
at a higher temperature, so it will also burn longer.
Taper candles are dipped by the wick. I think
sometimes the center starter wax in a taper
is more paraffin than the outside colored waxes.
Xylene, http://en.wikipedia.org/wiki/Xylene
(aka Goof Off, http://www.goof-off.com/)
should be able to remove what's left after you
chip off the majority of the mess. I'm not sure
what brand that goes by in the UK.

Viscosity will be a continuous function of temperature, and not a step one. A
week at temps above comfortable room temperature might give similar amount of
flow as a few seconds at "melting temperature."
I got a B in a graduate level engineering class on viscosity of glasses.

As I understand it, for a pure substance it's a step function, and for a
mixture it tends to be less abrupt. But hey, what would I know about
anything?

Somewhere around 40 degrees celsius.

Really?
Well, that explains it then. I thought paraffin wax melts at a few
hundred degrees, not merely 40. It could easily have reached that
temperature in my bedroom.

Wikipedia seems to confirm my experience:
