This high quality charcoal gives Jewelers the perfect heating surface for soldering. The charcoal gets hot increasing the temperature under the piece for more even heat distribution when soldering. Charcoal is also soft enough to allow pins to be used to secure jewelers' work.

Chemically prepared for soldering. Under flame, the charcoal glows and reflects heat back to work, making the flame more effective. Easily punctured to hold work. All are 1-1/2"thick. Size: 3 1/2'' X 2 1/4''
