A live brazing demonstration on the Castolin stand: a worktable with firebricks, metal sample pieces, flux jars and filler rods, next to a red rack holding two yellow Castolin gas cylinders with brass regulators. Visitors watch from the side, and the stand's red and white wall graphics fill the background.
