To provide a method for covering core using an ink jet or fog.
The method for covering a liquid or solid particulate core includes a process for dropping or floating the particulate core in a space and subsequently coating the same with a liquid coating during dropping or floating. The coating material of the liquid coating is performed by either one of a method (a) for spraying the liquid coating on the particulate core using the ink jet and a method (b) for moving the particulate core through the fog of the liquid coating. The particulate core is dropped or floated in the space and coated with a first coating composition containing a first reactant during the dropping or floating of the particulate core by one of the methods and the particulate core coated with the first coating composition is subsequently brought into contact with a second coating composition containing a second reactant reacted with the first reactant.
