SO489 = Charcoal Solder Block 7'' x 5''

HIGH TEMPERATURE CHARCOAL SOLDER BLOCK
Arguably the world’s best charcoal block. It is made of hardwood with great life and durability. This is a premium quality block so it will last 3 to 5 times as long. It also has better heat retention: great for platinum.

This chemically prepared charcoal block will glow under a flame and reflect heat back onto the work. It is a denser charcoal block but still soft so sticking in positioning pins to hold work in place will be easy.

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.
• 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.
