Quote "I found the bubbly reject casting..."
Did you use a de-gasser tablet in the crucible Ruairidh? Casting melted scrap can be a bit of an unknown and when I was at college we used de-gassing tablets held at the bottom of the crucible with a perforated plunger with a long handle.
Ghastly fumes but whisked away with the extract fan... good castings followed.
IIRC they came from a Birmingham based casting supplies firm Foseco
