Charcoal Solder Block

Description

This charcoal solder block is made from select, close-grained, knot-free wood chemically prepared by a special process. The charcoal under flame creates a reducing atmosphere and reflects heat back into the work for effective, soldering conditions. Heat is reflected to provide uniform intensity. Soft enough to be easily punctured to hold soldering work. Wrapping block in binding wire before use will retard cracking.
