--- Quote ---.....where do you get Calcium Carbide in handfuls?  I can find a source here for a one or two ounce tube, but that's all I've found.  I could use some for a lamp I've got, and I'd like to build an engine that runs off it.  That was the standard way to get acetylene all up through the thirties and forties, for welding.  Info would be highly appreciated. :scratch: mad jack

Have moved this to the (Re)Sources section.

We used carbide lamps for various purposes on the farm and it used to be stocked in agricultural merchants. Nowadays I think one of few disciplines that still uses carbide lamps is the caving fraternity - e.g. here where they have 1kg (2.2 lb) for GBP 8.35 or 3kg (6.6 lb) for GBP 20.75 - I guess you may have similar suppliers in the US?

Hi Dave

Rob

DMIOM:
No Rob - tisn't for me - I was just answering the queries that had cropped up in Chris's Stuart 10V thread (I think NickG was talking about atmospheric gas engines) but as they were continuing a wee bit OT I thought I would post the follow up here

Dave

Rob.Wilson:
Cheers Dave

I was trying to get some of this calcium carbide for a demo of "underwater fireworks" - acetylene and chlorine. A couple of the "normal" educational chemical suppliers don`t stock it - or at least not listed in their catalogues.

However, with that link Dave, a good supply of some carbide - a copy of miners lamp would make a great project:

My grandad tells stories that when they were at school they use to bring calcium carbide in their school pocket, throw it in an ink well and drop some water on it. Then they would light the ink well and it would act as a little desk lamp! I`m sure they weren`t meant to be doing that ....but a nice tale!


So who is making the first carbide lamp?
