Dry Application Processes

The classical dry application of ground enamel to cast iron objects is operated in addition to wet application. The cast iron enamel is dredged through a sieve onto the glowing object. The enamel powder melts and is subsequently melted smooth in a furnace. Multiple application yields thicker layers. 

For smaller cast iron objects, a dipping powder process can also be used, in which the glowing object is repeatedly dipped into the enamel powder. 

In sheet steel enameling (particularly for flat-ware), the powder electrostatic coating has become the preferred process. The electric voltage difference between the pistol and the object is with 60 to 90 kV slightly weaker than that 

Nondeposited enamel powder is recovered and reused, so that there are practically no losses of frit powder.
