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 wet enamel preparation process (“milling”) consists of the following seven sequential steps :
A clean furnace atmosphere is important for obtaining good enameling results.
Elevated concentrations of CO2 and/or H2O may slow down the emission of gases from the metal substrate thru the enamel layer during the fusion stage and under certain unfavorable circumstances result in enameling defects such as pinholes & fish-scales.
CO2 & H2O may accumulate inside the furnace, if the combustion system is leaking and/or the forced abstraction of combustion gases is not sufficient.
Regular furnace inspections and maintenance are therefore strongly recommended. Continue reading “Enameling furnace atmosphere”
