Four Boxes on the Right
The Top Box
Lamps (kantera) in the Meiji Era (1868-1912)
Those lamps used rapeseed oil and kerosene or paraffin oil together half and half. They were made of tin. Miners sometimes put more kerosene or paraffin oil than rapeseed oil in these lamps and they produced a lot of soot.
丸Maru: Round Type
角Kaku: Square Type
The Second Box
Gas Lamps (kantera) in the Late Meiji, Taisho, and Showa Eras (around 1900 to 1989)
Miners put water into the tops and carbide into the bottoms.

The Third Box
Safety Lanterns in the Meiji and Taisho Eras (1868-1926)
(1) Clanny-type Safety Lantern with Only a Mesh Chimney
(2) Safety Lantern with a Glass Skirt Using Rapeseed Oil or Fish Oil
The glass skirt would break when it was inclined near 45 degrees, causing its light to become as dangerous as naked lights of normal lamps.
The Bottom Box
Safety Lanterns in the Late Meiji, Taisho, and Showa Eras (around 1900 to 1989)
At first phosphorous matches were used to light them and later a lighter was installed in each of the lanterns. The tank and chimney were fastened with magnets which local people called eriki.
Volatile oil was used for this type of lantern. The operations of adjusting the flame and the ignition with matches or lighters were done from the bottom.
Description of the Cap Lamp
The cap lamp became generally used around 1931 to 1935.
