The Optical Magic Lantern Journal (June 1892)

66 done, after japanning, by lining or stenciling with japanners’ gold size. This, when dry enough to be just tacky, is covered with gold or silver leaf, or bronze powder, and then again baked, or in the case of the bronze powder or silver leaf, coated with clear gold size, and put in the oven to harden. Before putting on the gold size to which the gold, silver, or bronze is to adhere, the japan should be dusted over with french chalk, to prevent the metal sticking where it is: not wanted, and the gold size, which is nearly transparent, mixed with some pigment, such as yellow chrome, in order that the artist can see where he is putting it. Any superfluous gold size may be cleaned off with a piece of rag damped with turpentine. This must be done thoroughly, or the leaf or powder will adhere to the place. To be effective this method of decoration should be used sparingly, Gold size can be purchased at any oil shop ; a pennyworth will be sufficient for a dozen lanterns. Stencil paper may be prepared by coating thick writing or cartridge paper with turpentine. It is better to first draw the design ona piece of plain paper ; lay this on the prepared paper, and cut both through together with the point of a sharp knife. Some parts of the stencil must be left to hold the paper together; for instance, in the letter O, if the lines were cut tight round, the centre will fall out. In stencilling, the paper must be held close to the surface of the japan, and the gold size applied with a stumpy brush, care being taken to see that it does not get under the edges of the paper. Gold leaf cost about 1s. 8d, per book of twelve leaves, each 3in. square ; Dutch metal about gd.; | silver leaf, 1s. per book; bronze powder, either imitation gold or silver, can be had in 6d. packets from any dealer in artists’ materials. Sometimes it will be found that the japan does not dry readily; this is generally the result of the soda not having been completely washed off, or because there is some admixture of grease, most probably from the work being too much handled. Except to take out the brush-marks, it should not be touched until it is quite finished; and as the oven to be used by the lanternist will most likely be the same as the one used for | domestic cookery, he should be careful not to let | the work come in contact with the sides or bottom, and the door should be left open a little for ventilation. Also, if possible, some amicable arrangement ! should be made with the lady, or lady-help, pre siding over the cooking department of the house-! |! hold, as the odour of japan when baking, or being ‘* stoved,”’ as japanners say, is very different from that usually found in a well-ordered kitchen.

No. 20.— DAYLIGHT KODAK.” Tue Eastman Company will, with the commencement of this month, introduce a new style of Kodak at low prices, varying from 36s. The ordinary form of Kodak was described in our issue Of March, 1891. The new style, although similar in many respects, possesses many improvements and novelties. The chief improvement is perhaps a contrivance which enables a spool of film to be placed in, or taken from, the camera in open daylight—an arrangement which cannot fail to be appreciated. Fic. 1. Attached on each end of the film is a black and opaque strip of paper of particular length having the outer end gummed. When it is desired to place a new spool of film in the camera, first remove the roll-holder from ‘the back of Kodak, and cut the black paper be tween the two boxes about an inch from the empty box. Pull the end of the paper protruding from the fresh spool box and draw it over to meet the paper on the empty spool (Fig. 1), and fasten by moistening the gummed edge. The spool boxes can now be replaced in the roll holder and put in the camera, the full spool being on the left and the film over the exposing board Fic. 2. A é as in Fig, 2.
