Prior to the actual application, porcelain enamel slip need to be prepared in
accordance with the application requirements, such as fineness, set and specific
gravity. The traditional enamel preparation process ("milling") consists of the following seven sequential steps :

Nowadays there are also so-called ready-to-use and ready-to-mix
enamels available.
These enamels are already weighted & mixed in the appropriated quantities. Ready-to-use enamels are supplied complete with water, so those enamels can in theory be used immediately. Ready-to-mix enamels require just adding water & mixing prior to use. The benefits of RTU / RTM enamels are :
