This hillside dump contains safety fuse spools and 100 pound National Carbide containers.
The top of the lid reads “National Carbide – Factories – Ivanhoe, Virginia – Keokuk, Iowa.”
The bottom of the lid reads “Office – New York.”
The white on the ground is calcium carbide. Calcium carbide was used in miner lanterns and headlights.
I’ve included a few photographs of a personal Justrite carbide headlight. The calcium carbide went into the lower chamber, water in the upper. Combined, they produce acetylene gas. The lever on top of the lantern controlled the water flow into the carbide, which would control the size of the flame coming out of the front.
