The reason is very simple.
Acetylene has to be dissolved in acetone for delivery because it is
unstable and only liquifies at low temperture/high pressures.

Acetylene bottles are filled with a rigid foam and ecatone. This is why
they always have to be kept upright in use.
If you lay it on it's side and open the vlve, the acetone will run out
with acetylene still dissolved but foaming as it comes out.
Very dangerous situation.

I dont doubt what you post etc but not that long ago in the scheme of
things, people used acetylene lamps. They were used on the early cars and
in caving into the 1970s at least. (I recall seeing some potholers use them
in my teens.)

They worked by producing acetylene from the reaction between calcium
carbide and water from memory.

Yes. We were all handed one of those when visiting the Ice Caves near
Werfen in 1999.
