Definitions

  • the metal surfaces to be enamelled, before their introduction into the furnace, are moistened with the metal compounds by the heating of which the spinel like conversion is to be effected, the moistening being effected either by immersing the surface in a liquid containing these metal compounds, by spraying etc.
  • the moistening fluid has preferably added to it a suitable flux, such as boric acid or fluorspar.
  • suitable flux such as boric acid or fluorspar.
  • the rust which usually adheres to iron surfaces isan excellent spinel former, it may be made useful and advantageous in the present process by assigning to the rust the role or function of one of the spinel components in the heating action.
  • This will be recognized as an extraordinarily advantageous feature of the present invention because, thanks to the circum stance that rusty surfaces of any kind may be subjected to the process not only without detrimerit but with positive advantage, the present process is the first in the art which permits containing to 100 parts of water,
