Powder coating. Alien concept to me. (Seriously. Why not just spray paint them?)

Powdercoating is much more eco than spray paint. No nasty polluting solvents and it lasts longer. The commercial set ups use static electricity to get the powder to cling to the steel before heat soaking.
Enamel is the old school coating for appliances and it is actually powdered glass melted on to steel. As Christ pointed out glazing on pottery and porcelain is also a type of powdered glass.
Enamel used to describe paint is more or less a marketing term to try to attribute to it the shiny hard durable permanence of real enamel.
