Porcelain insulator markings

Porcelain insulator markings are one main step of porcelain insulator manufacturing process. For example, an insulator was used to impress the manufacturer's logo into the leather hard clay prior to firing.

Porcelain insulator markings

The types of porcelain insulator markings:
◆ Incuse markings-designs cut into the surface
◆ Embossed markings - Very few porcelain insulators have the raised markings known as "embossed" markings.
◆ Recess-embossed: porcelain insulator made by wet process porcelain usually used this type marking
◆ Under-glaze Ink (u-g): This marking was obtained by using a rubber ink stamp to apply the ink mark on the dried insulator clay body before the glaze was applied.
◆ Over-glaze Ink (o-g): This marking was applied by using a rubber ink stamp to apply the mark on top of the dried glaze before the glaze was fired. A colored glaze was used to make to make the marking.
◆ Sand-blast (s-b): few porcelain insulators manufacturers used this type markings
