Soldering Block

Charcoal Block used to solder on. As this natural charcoal block, it is good at absorbing oxygen during soldering to prevent firestain. Also it is soft allowing you to make dips in the charcoal block to make small round balls of silver. It also protects your surface from the heat of the flame torch. Some people tie iron wire binding around the charcoal block to stop it breaking over long use.
