Third operation
Directions: Take the 7 × 7-in. piece of copper and draw a 7-in. circle. With the dividers set 11⁄4 in., using the same centre, describe a circle. This outlines the 21⁄2-in. circle for the base. Drive up this disc as you did the one for the copper bowl on the wood block, making it as deep as possible. In the same way as you flattened the bottom of the copper bowl, flatten the bottom of this piece of work. Place the bowl over the round head stake. With your hammer drive on the outside. This driving with the hammer on the outside decreases the diameter and increases the length. You will remember that the copper bowl was driven up almost entirely by the use of the raising hammer on the inside and finished by work on the outside with the planishing hammer. This vase or jar calls for the shaping hammer. The vase is placed over the round stake and driven into shape by work on the outside with the shaping hammer. When the rough bowl shape is on the round head stake, drive the sides straight, beginning the strokes at the line of the base circle. Repeat till the sides begin to straighten and take the shape of the design. Take it off the round stake and place it on the anvil stake.
When the sides are symmetrical, mark with lead-pencil a line 3⁄4 of an inch from the top. Work the copper above this line, over toward the centre, until the opening of the vase is about 31⁄2 ins. in diameter. Smooth the work up with a planishing hammer. If the hammer marks made by driving the bowl into shape are carefully done they leave a very beautiful mottled surface of themselves.
Rim
Binding the flange to rim to solder
To make the rim for the lid to rest upon: Take the 3⁄8-in. strip of metal. Bend it into a circle small enough to fit on the opening left at the top of the vase. Be careful to have this just to fit, otherwise much filing will have to be done, and in this position filing is almost impossible. Cut it the right length, scrape both ends, and solder. Make it perfectly level so that it lies flat when placed upon the bench. Test it by placing it upon the top of the vase. File the top flat, bind the rim in place. Wash, then place bits of solder all around it and heat it until the solder runs. Cool off in water, file off all rough edges left by the solder, clean and polish.
