Unglazed rims of porcelain

Unglazed rims and borders are a missing border glaze on cups, mugs and bowls. Shelves are the upper edge (mouth rim) of a porcelain body. Especially thin-walled bowl cups can only be fired "upside down", i.e. with the opening facing downwards, otherwise the handle with its weight would distort the cup into an oval during firing.

This is why most manufacturers of thin-walled bowl cups - including manufacturers such as Meissen, Tirscheneuth and others - do not re-glaze the shelves. This is mostly for cost reasons. All cups and mugs of the Holst Porzellan/Germany collection HP11 are glazed on the rim! Nevertheless, missing rim glazes are not a defect, although they can show strong discolouration even after a short period of use.

When buying, please ask if the item is glazed or not!
