Type 94 Smoke Candle

[BOUGAINVILLE]

Here is my latest acquisition. A Type 94 Smoke Candle.

I would appreciate it if anyone could be kind enough to detail the 7 steps in the instructions as it would be quite interesting.

JAPANESE TYPE 94-A LARGE SCREENING SMOKE CANDLE

DESCRIPTION
TYPE 94-A LARGE SCREENING SMOKE CANDLE (STATIC)
The body of the candle is manufactured from 24 S.W.G. tin-plate, and a soldered seam runs down the side. The ends are closed with plates of the same material which are recessed and rolled on to the body. Fitted through the top closing plate is a smaller inner container to which is attached the igniter tube of brass. This inner container is secured to the larger one by a supporting piece which is threaded to take a screw on cover. The wooden carrying handle is attached to a metal ring which is secured to the head of the outer container by a nut and bolt.

FILLING
Both the body and inner container are filled with a C.T.C. type smoke mixture.
(a) Main Smoke Composition.
• Carbon Tetrachloride 36%
• Zinc Metal 30%

(b) Primary Smoke Composition.

ACTION
The translation of the label found on the candle, giving instruction for use, is as follows:

a) To ignite the candle, take off the cap and remove the scratch block. Then using its painted surface, rub the igniter head.
b) When the smoke spurts out, do not approach within two metres of the smoke port, as it gives out sparks.
c) The smoke has an extremely high temperature, do not expose the body to the smoke or use the candle near any inflammable material.
d) It is possible to use the candle from moving vehicles or on board ship, as well as on the ground.
e) When used on the ground it should be tipped into the wind.
f) A defective candle can he ignited by setting its smoke port near the smoke port of a candle that is already burning.

When the match head is rubbed it sets off the igniter composition, the thin walls of the igniter tube fall in and the primary smoke composition commences to burn. The walls and base of the primary smoke composition container are also very thin, these are melted and thus the main smoke filling is ignited. Smoke is vented through the hole in the top plate where the igniter is fixed. The burning time of the candle is 2 minutes 21 seconds.

The translation of the nomenclature is :
Model 94 Smoke Candle ( Large ) "A"
