IMO opinion it isn't candle wax.
It's a low viscosity fluid flow pattern.
Best candidate is water.
Best candidate for water is weather conditions and an open shaft.
If the shaft was open with an intact casing and the casing was concave. Eight sided pyramid and all.
We'd have a huge catchment area and sides that would direct the water flow toward the centre line of the casing.
I think it's possible that over thousands of years an appreciable amount of water could have been caught, directed and flowed down the shaft. In effect an artificial spring. Either intentionally or accidentally. Who knows?
There's also the solar still effect, ground water evaporation and condensation within the structure. The resulting water finding the path of least flow resistance, which is what water does.
Which seems to be the case today at the Bent Pyramid. Water flowing out about half way up the structure.
Any other suggestions?
