If you took a porcelain sign manufactured 100 years ago and kept it inside where all the air wasn't around it, that sign would look identical to the day it came off the construction line. The characteristics of porcelain enamel are just marvelous. Ultimately though the price killed porcelain sign making. It's labor intensive in comparison to paint or silkscreen on thin metal. You can't take a chunk of chintzy metal and put porcelain enamel on it. You've got to have anything great or it'll just crumble when it's being fired.
