Blister Tapping Ports Artistically Rendered
Three of the eight blister copper tapping bowels and launder that have had the build-up removed, cleaned, prepped and are ready for tapping. The blister launder is not water cooled and is covered with furnace brick to insulate it against the loss of the heat provided by the gas burners. When ready for tapping operations the inside of the launder under the brick is glowing a bright yellow hot. The white padding is a very dense fiberglass material resembling compacted cotton or wool and is capable of withstanding temperatures in excess of 2500 degrees without disintegrating.
