Fire Block, Ceramic, 5.7 x 3.7 x 2" (Each)

When using a ceramic fire block as your soldering / firing surface, it acts as a heat sink, which means it can take longer to heat items up enough to flow your solder, but is useful when soldering small, thin fragile items, or when you want to solder just one area of a larger piece.
