Illuminating Gas
Let me know if you want more from this book. Its 130 years old! It is in separate pictures since I could not attach the pdf.

You seem to be correct... It looks like it is more that 2 mb

I assume that the illuminating gas referred to is acetylene . . .
When burned in the correct atmosphere, it produces a very pure, white flame ─ apparently!

A long time ago I read about petrol gas. It was used for illuminating country houses.
Here is a complete description of the production and use of petrol gas.

1s. 6d. Daylight robbery!?!
Had'da a quick look too, and found this.

Is that a joke or what?

See illuminating gas is about 46% CO so I do not believe it is acetylene.

Dry/destructive distillation of wood, together with examining its products is an experiment kids do in elementary school. There's no acetylene inside.

It actually says that there is acetylene present in the "marsh gas" in the text.(The "marsh gas" amounting to 1/3 of the total gas volume).
If it is the "luminous" component is rather hard to disern from the text, but it is true that acetylene burns with a almost pure white flame if the
gas mix is right (I have several WW2 German calcium carbide mine lamps and the light from them is almost pure white) , and as such I believe it to be
a chief component of a good "luminous gas". Do not know much of the flame color of CO but IIRC it is almost pure blue e.g. invisible or poor for
illumination.
Any sufficiently advanced technology is indistinguishable from magic.

I get it!
It seems that for some reason best known to yourself, you believe I said something or other about the decomposition of wood . . . ?

I really doubt there's acetylene inside, and I thought you meant to say the illuminating gas aka coal gas is acetylene which is never made by this
method. My apologies if I was mistaken.

I agree I do not believe acetylene is in illuminating gas. I have looked this up and it is not in it.

Acetylene is still popular as an illuminating gas! http://carbidelamp.net/

In the way I am referring to illuminating gas is the way that it is referred to in the book.

Even if it were CO, the colour the gas burns is immaterial - the setup (for the last 100+ years, at least) uses a mantle, like on a coleman lamp - the
hot thorium oxide glows bright white from heat.
Before that it had to be wood or coal, things that burn bright, though.

Yeah, it has some advantages over electrical setups, especially for speleology. It produces more heat, which is sometimes great when you're couple of
hundreds of meters in the Earth's crust, where it's very cold. One carbide lamp and a Mylar foil blanket keep you warm.
