A time proven technique for effective soldering. Under flame, the charcoal glows and reflects heat back in to work, making the flame more efficient. Select, close-grained, knot-free wood is chemically prepared with a special process for soldering. Easily punctured to hold work. Used to support metalwork when soldering, also heats up and helps maintain the temperature of the piece.
