Warmthe pitch on the block, press the cupmouth downward on the melted sur-face and put a weight on the top untilcool, or, what is simpler, you can layit on a sand-bag, and do without thepitch-block. The first method is how-ever the most secure. Then sketch on64 the ornament and outline it with a tracer, Hammerlightly if you do not want the lines to Workshow inside and firmly if you do. If, for example, you wish to raise arounded band around the cup near thebrim. Trace a line above and belowall round the cup, the distance apartbeing the width of the molding. You. Fig. 18. will then remove the cup from thepitch-block, warm it slightly in theblowpipe flame, and take out the rewarm the pitch on the block,lay the cup on its side, and press it wellinto the pitch. The space between thetwo traced lines can then be beaten outwith rounded punches to the projection5 65 Hammer required. Other projections which may Work be required lower down within the cup must be done with the snarHng-iron, Fig. 19. but these should only be very slight,as the cup would be difficult to clean66 when in use. Then clean, polish, andfinish as before. Another kind of joint which may beused in metal jugs or vases, or in any casewhere the joint doesnot matter, is the inter-locking joint (see ), Cut out the metalto the shape required,making it ^ inch longerthan is necessary for abutt joint, giving thus alap of ^ inch, and divide —each of the edges to bejoined into an equal
