Directions for Babbitt: Heat Babbitt to 850 degrees F and throw liberal amount of flux on surface. Stir vigorously from top to bottom with skimmer. Then stir horizontally in circular manner to collect skimmings at center and skim off. Repeat until there is a clean separation of metal and oxides.
Directions for Zinc: Heat Zinc until quite molten and then follow the same instructions for Babbitt.
Note: Flux produces a white smoke that is harmless, but ventilation is recommended.
