Take a manageable length of 16 gauge silver wire and ball up one end.If you have never balled the end of a piece of wire before simply hold the piece in a pair of tweezers and gently move the flame from your torch up and down the bottom of it until a ball forms. Holding the wire straight up and down in the flame will ensure an even ball.
After you have made the ball you can round it out using a cup bur which matches the gauge of wire you’re using. If you are using fine silver this step won’t be necessary as it forms a perfect ball when melted.
Pro Tip: The hottest part of your flame is the area just in front of where the smaller, inner flame, touches the larger outer flame. You can manipulate the heat you’ll need by watching this part of your flame.
