This charcoal block measures approximately 70mm x 70mm in size, with a 30mm thickness.
This Compressed Hard Charcoal Block with Crucible Channel is the ideal traditional soldering surface.
Charcoal is perfect for soldering on due to its heat reflective properties, which help effectively reach the optimum temperature quicker, and create a cleaner soldering environment.
When placed under a flame, this solid carbon material causes a reducing atmosphere by absorbing the oxygen surrounding the piece, preventing oxidation and firestain.
Use this specially compressed charcoal block for soldering smaller pieces or making minor repairs to joins.
Simple shapes can also be carved out of the block and melted into finished forms from pieces of metal.
This hard charcoal block uniquely features a tapered pouring channel, which is useful for melting small amounts of scrap metal into ingot moulds.
