In France vitreous enamel is regulated by the AFNOR decision NF92-010 of january 1977 as a :
« Une substance résultant de la fusion ou du frittage de constituants non-organiques et destinés à former un produit vitrifié fondu ou capable de l’être, sur un support métallique. La température de fusion des émaux est supérieure à 500°C (932°F).»

Then vitreous enamel is a GLASS produces by a bled of different minerals (silice, feldspath, quartz...) melted at almost 1200°C/2192°F
This glass is then reduced in powder and mixed with water with other minerals to be apply onto steel.

PLEASE NOTE that enamel doesn't contain lead !

Once on steel, enamel is melted at a high temperature (780-820°C / 1500°F).

Several coats of enamel can be made.
