Made from select, close-grained, knot-free wood. Creates a reducing atmosphere and reflects heat back onto workpiece for effective soldering conditions.
Soft enough to allow work to be pinned or pressed into its surface. Wrapping binding wire around the perimeter of the blocks will help them last longer.
