This chemically prepared charcoal block will glow under a flame and reflect heat back onto the work. It is easily punctured to hold work in place.
Charcoal solder blocks are very useful in the soldering process:
- They don't absorb much heat. Instead they reflect it back helping to heat up pieces on it much faster.
- They create a reducing atmosphere that consumes the oxygen around the piece being soldered. This helps to prevent fire scale.
- They are soft enough to have pins pushed into them for holding pieces in place.
- Their surfaces can be sanded down if they get too worn.
- If they are broken, the pieces can still be used.
There are a few drawbacks too:
- They can crack or break after heating.
- They can keep burning after the soldering is done.
- They can be messy.
- They can give off fumes, so use in a ventilated area.
- They get used up.
