Design for a card tray
After shaping, the design may be applied by means of transfer paper and the lines lightly scratched on the surface. Then imbed the tray in pitch and outline the design by following the lines with a narrow chasing tool. Reverse the tray on the pitch and, with a chasing tool of suitable shape, raise the body of the design to the height desired. Reverse on the pitch again and with a flat tool true the outlines and smooth the background. Remove from the pitch, trim the edge of the tray if it is forced out of line, clean with pumice stone and buff.
Method of shaping with the hammer
All the foregoing articles may be agreeably coloured by painting them with, or immersing them in, a weak solution (boiling) of liver of sulphur. If soft solder has not been used, another pleasing finish may be secured by applying a thin coat of lubricating oil and heating gently until the oil is volatilized. An antique green or verdigris finish may be obtained by painting with a mixture of acetic acid and copper carbonate. Several coats may be necessary; and it is desirable to lacquer the surface to ensure permanency.
Work in Other Materials
A CANDLE SHADE
The materials and tools for this problem are six ply card-board in dull shades of gray, brown or green, and with mat surface; Japanese paper of average thickness; passe-partout binding a little darker than the card-board and of harmonizing colour; paste; a penknife with a thin blade; and a water colour outfit.
Of the drawings included in the group on the opposite page one shows a development of the surface of the candle shade which is the subject of this problem. Referring to the elevation it will be seen that if the edges AE and DH be continued until they meet at O, OE and OH are really equal to the radii of the outer arc of the development shown in the upper part of the group, and OA and OD, to the radii of the inner arc. This upper developed surface really forms the pattern of the candle shade.
